Unimaginable beauty, that is what you see visiting Mammoth Hot Springs in Yellowstone National Park. It is located 5 miles south of the Gardiner, North Entrance to Yellowstone. The area is easily accessible year-round by car. Coming from Norris Geyser Basin on the Grand Loop Road south, you descend through the switchbacks into the valley until the first thing you notice is the steaming otherworldly terraces. Our view included storm clouds hovering over Gallatin Mountain Range, making a beautiful backdrop to the valley. It’s primarily a Montanan range, though significant parts lie in Wyoming. More than half of the range lies in Gallatin National Forest, though its southern portions lie in the northwestern quarter of Yellowstone National Park.

Where to Stay When Visiting Mammoth Hot Springs in Yellowstone
There are several options for lodging in or near Mammoth Hot Springs. It’s important to book your accommodations well in advance, especially during the peak summer season when lodging can fill up quickly.
- Mammoth Hot Springs Hotel and Cabins: This historic hotel lies in the heart of the Mammoth Hot Springs area and offers a variety of accommodations, including hotel rooms and cabins
- The town of Gardiner, Montana, is just outside the park’s North Entrance and offers a variety of lodging options, including hotels, cabins, and vacation rentals.
- There are several campgrounds in the Mammoth Hot Springs area, including the Mammoth Campground, which is within walking distance of the hot springs.
Mammoth Hot Springs Hotel and Cabins in Yellowstone
They built the Mammoth Hot Springs Hotel in 1911 and recently renovated all the rooms in the hotel. I highly recommend staying in the park just for the proximity to everything. The hotel is within walking distance of the Mammoth Hot Springs Terraces and the Mammoth Hot Springs Historic District, making it a convenient base for exploring the area.
Although you give up TV, Internet access, and cell phone coverage for the privilege of early access to the park. I gladly give it up to be close to wildlife, and enjoying other amenities within the park is worth the loss of technology access. The newly renovated hotel rooms are beautifully done, keeping the original authentic feel while maintaining a top-notch and updated style. The rooms can be a real value price-wise for those who want to stay within the park.
Overnight Adventure at Mammoth’s Historic Frontier Cabins
We stayed in a rustic frontier cabin that we had reserved a year in advance. Check-in and check-out were fast and efficient. The cabins are simple but comfortable, with basic furnishings and amenities. Our cabin featured two queen beds and a private bath, though some cabins have shared bathrooms.
Although our cabin was a duplex, we didn’t experience any issues with noisy neighbors. The cabins are clean, reasonably spacious, and heated. It would be nice to have coffee in the room and access to a small refrigerator, but the hotel does provide complimentary coffee and tea in the lobby.
Our cabin also came with a charming bear-shaped soap that I kept as a souvenir. Some cabins even feature privately fenced hot tubs for an additional cost. I really appreciated the focus on simplicity and immersion in nature here. Wildlife was abundant on the grassy common area—watching ground squirrels scurry under porches while large elk wandered nearby was fascinating.
These cabins are definitely on the older side, so don’t expect luxury accommodations. That said, I loved the rustic charm and would happily stay here again. They offer great value, a sense of isolation, and all cabins are pet-friendly. Like all Yellowstone lodging, this property emphasizes environmental responsibility, making it a conscientious choice for nature lovers.
Exploring Mammoth Hot Springs in Yellowstone: Walk the Grounds and Spot Wildlife
The small porch at the front of our cabin was the perfect spot to sit in the morning or evening, watching elk and ground squirrels roam the area. Walking along the cabin loop road, it’s important to be cautious around elk. Yellowstone National Park is home to a large elk population, and visitors need to be aware of the risks of encountering these animals.
During the fall mating season, or “rut,” male elk can become aggressive and territorial, sometimes attacking anyone who gets too close. Feeding elk—or any wildlife—can also make them aggressive or dependent on human food, which is dangerous for both people and animals. Always maintain a safe distance, follow park guidelines for wildlife viewing, and take the Yellowstone Pledge. Sadly, visitors who ignore these rules get injured every year.
Dining in Mammoth Hot Springs
There are several dining options available in Mammoth Hot Springs, including:
- Mammoth Hot Springs Hotel Dining Room: This full-service restaurant is located inside the historic Mammoth Hot Springs Hotel and serves breakfast, lunch, and dinner. The menu features classic American dishes with a focus on locally sourced ingredients.
- Terrace Grill: This casual dining spot is located next to the Mammoth Hot Springs Terraces and offers a variety of fast-casual options, including burgers, sandwiches, and salads.
- Map Room Lounge: This cozy lounge is located inside the Mammoth Hot Springs Hotel and serves a variety of cocktails, beer, and wine. The lounge also features a fireplace and comfortable seating, making it a great spot to relax after a long day of exploring.
- General Store Deli: This casual spot is located inside the Mammoth Hot Springs General Store and offers a variety of grab-and-go options, including sandwiches, salads, and snacks.
- Bear Den Gift Shop: This gift shop features a small café area that serves coffee, tea, and pastries. It’s a great spot to grab a quick snack or drink while shopping for souvenirs.
Delight for the Senses in the Mammoth Dining Hall
We started the day with an early morning walk. The air was about 40 degrees, and the wind was blowing from the north. We bundled up in layers. For a full-service dining experience, you can eat at the Mammoth Hotel Dining Room. We had a light breakfast in the Mammoth Hotel Dining Hall. The food is satisfying here. They don’t take reservations for the dining room, so seating is on a first-come, first-served basis.
We arrived at the dining room right when it opened at 7 AM and were seated immediately. While there’s a nice breakfast buffet, we decided to order from the menu. The short stack of pancakes was huge—big enough for two—and the huckleberry syrup was excellent. I had eggs with toast; the eggs were light, fluffy, and delicious.
The service was outstanding. Our server was attentive and even asked about our adventures in the park so far. When we noticed the couple across from us hadn’t been served yet, we mentioned it, and our server promptly took care of them.
Grab a quick snack at the Terrace Grill
The Terrace Grill is a great choice for a light and quick meal. It’s cafeteria-style: you place your order, pay, and wait for your number to be called. Then you pick up your food at the counter and take it to your table. Service moves quickly once you reach the counter.
The evening we visited, the grill was busy. I ordered a cheesesteak sandwich and a glass of Chardonnay, while Barry went with a hot dog and a beer. The seating area features large windows with stunning views of the mountains surrounding the valley.
The Terrace Grill also has a separate ice cream counter, and their ice cream is excellent—I highly recommend trying the huckleberry flavor. Portions are very generous and can easily be shared between two people.
Best Things to Do at Mammoth Hot Springs in Yellowstone NP
There are plenty of things to do and see in the Mammoth Hot Springs area of Yellowstone National Park. Here are some of the best:
- The major attraction in Mammoth Hot Springs is the terraces, which are made up of unique mineral formations that hot springs have created over thousands of years. Visitors can walk along the boardwalks to explore the different terraces and see the colorful and intricate formations up close.
- Fort Yellowstone Historic District includes several buildings that were once part of Fort Yellowstone, a military outpost established in the early 1900s to protect the park. Visitors can take a self-guided tour of the area to learn more about the history of the park and the role of the military in its development.
- There are several hiking trails in the Mammoth Hot Springs area, ranging from easy strolls to more challenging hikes. Some of the most popular trails include the Beaver Ponds Loop Trail, the Bunsen Peak Trail, and the Wraith Falls Trail.
- The Mammoth Hot Springs area is home to a variety of wildlife, including elk, bison, bears, and coyotes. Visitors can often see these animals from the safety of their cars or by taking guided wildlife tours.
- The park offers a variety of ranger-led programs, including guided hikes, campfire talks, and educational programs for kids. These programs are a great way to learn more about the park’s history, geology, and wildlife.
Everything you need to know about the Mammoth Terrace Walk
Mammoth Hot Springs is a short walk from the hotel and is best viewed earlier in the morning or later in the afternoon to beat the crowds and tour groups. Our morning strategy had become that we wake early to beat the crowds. The crowds that by midday make it hard to experience the sights of Yellowstone.
The Mammoth Hot Springs is divided into two main areas: the Lower Terrace, which features all boardwalks covering about 1.5–2 miles, and the Upper Terrace, a one-way 1.5-mile road.
For the Lower Terrace, there are four parking lots plus one overflow lot. At the Upper Terrace Drive, you’ll find one large parking lot just before entering the one-way road and two additional lots along the drive. Several pullouts along the route make it easy to stop for photos.
I recommend picking up the “Mammoth Hot Springs Trail Guide” from the visitor center (suggested $1 donation). It provides helpful information and descriptions of the unique features throughout the hot springs.
Self Guided Walking Tour through the Lower Terrace
The boardwalk trail at Mammoth Hot Springs is about 1.75 miles long and takes just over an hour to hike, climbing roughly 300 feet in elevation.
One of the most remarkable features of Mammoth Hot Springs is its ever-changing travertine terraces. The striking colors of the pools come from extremophile bacteria that thrive in the thermal waters. As the hot spring water evaporates, it deposits limestone, gradually forming the travertine. Over thousands of years, boiling water from the springs cooled and left behind calcium carbonate, creating the stunning terraces visible today.
I kept thinking how otherworldly this must have seemed to the early explorers. Steam rises in clouds from countless vents, while eerily stunted trees, encased in calcium, stand amid the encrusted cascades of the terraces. The soft, creamy tones of the travertine, set against smoky, darkened skies, give the entire area a surreal, almost dreamlike quality.
The Allure of Mammoth Hot Springs’ Lower Terrace
Starting at the trailhead near the Lower Terrace’s parking lot, we followed the boardwalk as we crossed a footbridge down a few stairs before reaching the Canary Spring. Mesmerized, we lingered for a bit.
This vantage point at the end of the boardwalk overlooking Canary Springs is a great place for trying to capture the colors and contours of the spring; NO matter how many pictures can you take in, you still won’t capture the essence of Yellowstone because you must see it, hear it, smell it, live it to truly experience it.
From Canary Spring, we continued along the boardwalk and came to New Blue Spring, named for its striking blue color created by the reflection of blue light off the silica-rich water.
Next, we passed Cupid Spring, famous for its intricate, delicate formations that resemble miniature terraces, with unique pink and white hues. Finally, we reached Cleopatra Terrace, named for its resemblance to a cascading waterfall. To me, the smooth surface reminded me of reptile skin, adding to the surreal beauty of the terrace.
One of the most striking features of the Lower Terrace is Minerva Terrace, named after the Roman goddess of wisdom. Its vibrant orange, pink, and white colors come from thermophilic (heat-loving) bacteria and algae thriving in the hot water.
Nearby, Jupiter Terrace lives up to its name, evoking the grandeur of the Roman god. The terrace’s impressive white and beige hues are formed by calcium carbonate deposits left behind by the hot springs, creating a breathtaking natural sculpture.
Exploring the Otherworldly Main Terraces at Mammoth Hot Springs
The Main Terrace is made up of a series of smaller terraces and pools, each with its own unique features and formations.. Most of the Main Terrace is dry, with a constant white surface that is a stark contrast to the orange and yellow of the active springs. The grey skeletons of the dead trees that punctuate the white plain of the upper terrace give it a bit of a macabre aspect. Just beyond are the Devil’s Thumb formations.
Next, we encountered the Palette Spring. Palette Spring is located in the northern portion of Mammoth Hot Springs. It’s created by flowing water and heat-loving bacteria, which grow on the surface.
Impressive Liberty Cap
Just beyond Minerva Terrace stands Liberty Cap, a towering travertine formation that rises 35 feet like a giant mushroom. Once an active geothermal vent, Liberty Cap became extinct long ago. Named in 1871 for its resemblance to the peaked caps worn during the French Revolution, it sits near Terrace Mountain, the largest known carbonate-depositing spring in the world. In the morning mist, the huge mineral deposits gurgle and steam, creating an ethereal scene.
From Liberty Cap, we headed back toward the parking lot, making sure to stop at Opal Terrace, known for its delicate formations and vibrant colors. Just beyond Opal Terrace is the small Joker Spring, followed by Bath Lake, each offering unique and captivating features along the boardwalk.
Self-Guided Walk of the Upper Terrace
The Upper Terraces require that you get back in your car and drive a minute up the mountain. The road is narrow, steep, and winding, so drive carefully and watch for other vehicles, pedestrians, or wildlife. To access the Upper Terraces, the road is a 1.5-mile one-way loop that you can drive in your car. You can see some thermal features driving the road, but if you have the time, I recommend getting out of your car for a closer view.
We began our hike at the trailhead near the Upper Terrace Parking Lot. Our first stop was Angel Terrace, named after an early settler who thought the terrace resembled an angel with outspread wings.
Along the way, we passed Grassy Spring and several unnamed thermal areas, punctuated by ghostly tree skeletons. Next, we came to Narrow Gauge Terrace, named for its narrow white calcium carbonate ridges and steep drop-offs. We also passed the stark, white cliff-side of New Highland Terrace, which is currently inactive.
Prospect Spring was active, with hot water bubbling up and flowing across the surface. Next, we reached Orange Spring Mound, named for its bright orange and green colors, created by thermophiles thriving in multiple vents of the hot water.
As the boardwalk loop returned toward the parking lot, we passed the Dry Bath Lake, Sulfur Pits, and White Elephant Back Terrace. The White Elephant Back Terrace fissure gets its name from its unique, complex shape, resembling the back of a white elephant. Its striking colors and patterns result from variations in temperature, mineral deposits, and bacterial activity across the terrace.
On our way back to the parking lot, we were surprised to see a male mule deer sprinting into the woods, a perfect reminder of the abundant wildlife in the area.
The Fort Yellowstone Historic District
The Fort Yellowstone Historic District is a collection of buildings and structures that were part of the original Fort Yellowstone military post, established in 1891 to oversee park management and protection. All the buildings with red roofs are part of Fort Yellowstone. The fort was built when the U.S. Cavalry, Company M, managed the park for 32 years (1886–1918). Today, the district is listed on the National Register of Historic Places and is recognized for both its architectural and historical significance.
The Albright Visitor Center
The Albright Visitor Center is named after Horace Albright, the second director of the National Park Service, who played a key role in developing and expanding Yellowstone National Park.
The center features exhibits on the park’s geology, wildlife, and human history, along with interactive displays and a bookstore. It is open year-round, though hours vary by season. The building was originally constructed in 1909 as a U.S. Army hospital and was later converted into a visitor center and museum in 1957.
The visitor center is convenient to Mammoth lodging, providing access to Wi-Fi. It is a hub for information on park services and activities, including guided tours, hiking trails, and ranger-led programs. There are informative animal exhibits on the first floor, which include well-done taxidermy mounts of wildlife found in the park. The Yellowstone Forever store has quality books and merchandise that can be purchased. Bathrooms are in the basement.
Old Fort Yellowstone: Whispers of History in the Heart of a National Treasure
The Fort Yellowstone post was established to protect and manage the park, which had been designated as the first national park in the United States in 1872.
After the National Park Service was established in 1917, the military’s role in managing Yellowstone National Park gradually diminished. Fort Yellowstone was decommissioned in 1918, and many of its buildings were repurposed for use by the Park Service. Today, the remaining structures serve as offices and employee housing. Mammoth Hot Springs staff occupies most residences, so visitors should be respectful when viewing the buildings.
You can explore the beautiful complex on your own via a self-guided tour or join an evening Ranger tour, which lasts about an hour.
Throughout the Mammoth Hot Springs complex, elk are everywhere, grazing both day and night. They love the Kentucky bluegrass originally planted by the U.S. Cavalry when they managed the park.
Most of the elk you’ll see are cow elk (females)—until rut season in September and October, when bull elk (males) with their shiny antlers enter the area. The green lawns are also home to plenty of Uinta ground squirrels, scurrying about and adding to the lively scene.
Hiking Trails at Mammoth Hot Springs
Popular hiking trails in Mammoth include Beaver Ponds Trail, Bunsen Peak, Wraith Falls, Lava Creek, Blacktail Deer Creek to Yellowstone River Trail, Rescue Creek Trail, and Sepulcher Mountain. Don’t forget to carry bear spray and make lots of noise! You’re in bear country.
Beaver Ponds Loop Trail is an easy 5-mile loop trail with scenic views of the surrounding mountains and passes through several beaver ponds. It’s a great trail for wildlife viewing and birdwatching.
PRO Tip: Bears are highly active along this trail. Be bear aware. Carry bear spray or travel in a group.
Best views from Bunson Peak
This is a moderate hike with an elevation gain of 1300 ft, approximately 4.2 miles round trip. First called “Observation Peak” in 1872, they later renamed it to honor German chemist Dr. Robert Bunsen. It is advisable to have sturdy walking or hiking shoes, as the trail is composed of rocky scree in some areas. A good trekking stick provides stability on the switchbacks. The mornings can be cool, so dress in layers with a good men’s and women’s hooded fleece that can be removed as the temperatures warm.
The trail has many switchbacks as you trek the ridge with excellent 360-degree views. There is a cabin-weather station at the top of the mountain. I would suggest doing the trail in the morning and bringing a picnic lunch to enjoy at the top of the peak. Take a lot of water and some snack food.. Be sure to have a refillable water bottle to quench your thirst.
Note: Because of the raging floods of last summer, the boiling river is currently closed as it seems it may no longer exist
Soak in the Boiling River
The boiling river is along the Gardiner River. The boiling river is a natural hot tub. This naturally created the hot spring when the waters from Mammoth Terraces enter the chilly waters of the Gardiner River. A short trail along the river’s edge gives access to the parking lot. There is one primitive bathroom in the parking area. They clearly mark the parking area. However, it is the only parking area between Mammoth and Gardiner.
Carry towels and wear your bathing suit if you plan to take a dip in the pool. I would recommend that you bring your water shoes with you, as the rocks can be slippery and difficult on your feet. The water can invigorate. However, the current can be swift at different times of the year. This hot tub is popular with locals in the summer, so go early.
Just a mile farther on Hwy 89, you will cross the 45th parallel of latitude; there is a sign marking the line. The 45th parallel is an imaginary line that circles the globe halfway between the equator and the North Pole.
Walking Tour Gardiner, Montana
Gardiner, Montana, is only 5 miles heading north on Hwy. 89. You follow the Gardiner River as you drive toward Gardiner. The river is good for fly-fishing. Gardiner is an excellent location to stock up on a few groceries and view the Roosevelt Arch. Johnson Gardiner, who was a fur trapper in the early 18th century, is how the river and town got their name. In the 1830s, he worked in northwestern Yellowstone and sold his furs to the American Fur Company.
The Gardner River flows into the Yellowstone River. All 35 miles of the entire river are within Yellowstone National Park. It is a very quaint western town with a few shops and restaurants that can easily be walked in an hour. Gardiner Gifts is a large gift shop with a wonderful selection of souvenirs. The selection includes various candies, huckleberry products, clothing, ice cream, and other unique products.
In the basement section, we found metal art and chose a fish that would define this trip for us. Before walking to the Roosevelt Arch, take the time to stop at the Yellowstone Forever. This nonprofit supports Yellowstone through educational programs and tours, with all proceeds funding initiatives like trail rehabilitation, youth programs, and wildlife preservation.
One trip you can book through Yellowstone Forever is a wildlife tour with Flying Pig Raft Company. While it costs about $95 per person, the tour covers the route from Gardiner to the northeast section of the park and back, offering an immersive wildlife-viewing experience.
Walk through the Roosevelt Arch
The Roosevelt Arch serves as the original entrance to Yellowstone and is now the park’s northwest entrance. This massive stone structure was completed on August 15, 1903, after construction began on February 19, 1903, under the supervision of the U.S. Army at Fort Yellowstone.
On April 24, 1903, Theodore Roosevelt laid the official cornerstone. During his dedication speech, he declared that Yellowstone was “For the benefit and enjoyment of the people,” a phrase now inscribed on the arch itself.
The towers are 52 feet high, 13 feet square at the base, approximately ½ that at the top, 25 feet apart. The side walls are approximately 40 feet long . They built the entire structure of basaltic rock. The Arch permits vehicles just under 25 feet to pass through the center.
The Mammoth area has much to offer, so consider staying multiple days. The Mammoth Hot Springs stay open through the winter and are a good jumping-off point for snowmobiling and cross-country skiing. I think I would like to revisit this spot in the winter just for the solitude it brings!
