This just might be my favorite geyser basin in Yellowstone—the dramatic colors are quite exceptional. A journey through Midway Geyser Basin in Yellowstone National Park is an adventure for the senses. For most visitors, the major attraction is Grand Prismatic Spring, and for good reason. The sheer size of the pool and the wonderful colors surrounding it are incredibly impressive. Unlike Norris Geyser Basin, the vivid colors of this iconic spring are breathtaking. The brilliant bands of color ripple outward from the deep blue center, creating a scene that looks almost otherworldly.
For us, though, the experience went beyond Grand Prismatic. Excelsior Geyser, Turquoise Pool, and Opal Pool each had their own personality—steaming, shimmering, and impossibly blue. Together, they made Midway Geyser Basin one of the coolest geothermal areas we explored in Yellowstone. No question about it.
Getting to Midway Geyser Basin
Getting to Midway Geyser Basin is easy once you’re traveling along Yellowstone’s Grand Loop Road. The basin is located between the Old Faithful area and Madison Junction on the park’s western side.
From Old Faithful, Midway Geyser Basin is about 6 miles north along the Grand Loop Road. From Madison Junction, it’s approximately 10 miles south. Look for the signed entrance to the Midway Geyser Basin parking area near the Firehole River.
Parking can be extremely difficult during the busy summer months. Midway Geyser Basin is one of Yellowstone’s most popular stops, largely because of Grand Prismatic Spring. Arriving early in the day or later in the afternoon can make finding a parking space easier and may also mean fewer crowds on the boardwalk.

Midway Geyser Basin Travel Guide: What to Know Before You Go
A little planning can make your visit to Midway Geyser Basin much more enjoyable.
- Arrive Early or Late in the Day: Midday is often the busiest time at Midway Geyser Basin. Arriving early in the morning or later in the afternoon can mean fewer people and an easier time finding parking.
- Check the Weather: Weather can make a big difference in what you see. On cool mornings, steam and mist can partially obscure Grand Prismatic Spring. While this can make photography difficult, the mist creates an entirely different atmosphere around the thermal features.
- Bring Your Camera: Grand Prismatic Spring is one of the most photographed sights in Yellowstone, so you’ll want your camera ready. A telephoto lens can also be useful for wildlife and distant details throughout your Yellowstone travels.
- Plan for the Grand Prismatic Overlook: If you want the famous elevated view of Grand Prismatic Spring, you’ll need to hike the trail from the Fairy Falls Trailhead. Wear sturdy hiking shoes, bring sunscreen, and carry a refillable water bottle. There are no water stations along the trail.
- Dress in Layers: Yellowstone’s weather can change quickly, even during summer. A hooded fleece or light windbreaker makes it easier to adjust as temperatures change.
- Know the Wildlife Safety Rules: If you’re continuing onto nearby trails, check with a ranger for current wildlife activity. Carry bear spray in areas where it is recommended, and make noise so wildlife knows you’re approaching.
- Stay on the Boardwalk: The ground surrounding the thermal features is fragile and can be dangerously hot. Stay on designated boardwalks and trails, and never step off the path for a better photograph.
- Give Yourself Enough Time: Don’t rush through the basin just to see Grand Prismatic Spring. Excelsior Geyser, Turquoise Pool, Opal Pool, and the Firehole River are all part of the experience.
The Journey Begins: A Walk Through Nature’s Most Colorful Creations
Like everyone else, we came to Midway Geyser Basin to see Grand Prismatic Spring. We arrived around midday, and the parking situation was, to put it mildly, ridiculous. Cars filled the parking area, and tour buses added to the congestion. If you’re visiting between June and August, be prepared for crowds and limited parking. Arriving early or later in the afternoon is a much better strategy.
Our walk into the basin begins at a small footbridge crossing the Firehole River. Even before reaching the geothermal features, we could see steam rising from the runoff as it flowed toward the river. It was a pretty good preview of what was waiting ahead.
The Firehole River is a major Yellowstone waterway that eventually flows into the Madison River. Here, the warm water from the geothermal features mixes with the river, creating those mysterious clouds of steam that make this part of Yellowstone feel almost otherworldly.
Excelsior Geyser Comes Into View
As we reached the other side of the bridge, Excelsior Geyser immediately grabbed our attention. Huge amounts of water pour from the geyser’s crater into the Firehole River, surrounded by colorful thermal runoff and billowing clouds of steam.
The colors in the water are created by thermophilic microorganisms living in the warm environment. Against the deep blues of the thermal pools and the white clouds of steam, they create an incredible contrast.
This was our first real glimpse of the geothermal wonderland ahead, and it certainly got our attention. Grand Prismatic Spring may be the star attraction, but Excelsior Geyser is an impressive way to begin the walk through Midway Geyser Basin.
At the far end of the bridge, you see water gushing about 4,050 gallons per minute from the Excelsior Geyser into the Firehole River. The colors in the channel water from the bacterial mats are mesmerizing. The boardwalk is a 0.8-mile loop boardwalk trail that starts with Excelsior Geyser, Grand Prismatic Spring, Opal geyser, and the Turquoise Pool.
Experience the Mighty Excelsior Geyser in Yellowstone’s Midway Geyser Basin
Excelsior Geyser is an enormous dormant fountain-type geyser and one of the most impressive features in Midway Geyser Basin. After a period of major activity in the late 19th century, the geyser went quiet for decades. Then, in 1985, Excelsior suddenly rumbled back to life with a spectacular series of eruptions that lasted about 47 hours.
During that eruption, columns of water reportedly reached heights of up to 300 feet. Today, Excelsior is quiet, but the massive crater is still an incredible sight. Gigantic clouds of steam rise from the deep azure-blue pool, sometimes making it feel as though you’re standing in the clouds.
Jagged rock formations and terraces surround the crater, offering a glimpse into the immense geothermal forces beneath Yellowstone. Standing beside Excelsior, it’s hard not to think about the much larger volcanic system lying beneath our feet.
When we walked past the geyser, steam enveloped us, but we could still catch glimpses of the deep blue water below. Words really don’t do justice to what it’s like to walk along the boardwalk while clouds of steam whip across the basin. For a few moments, it felt like we were walking through the clouds ourselves.
The Vibrant Colors of Grand Prismatic Spring
Grand Prismatic Spring is the star of Midway Geyser Basin, and it doesn’t take long to understand why. The brilliant blue center is surrounded by bands of orange, yellow, green, and brown, creating one of the most spectacular geothermal scenes in Yellowstone.
The colors aren’t simply a result of minerals in the water. Thermophilic microorganisms thrive in the different temperature zones around the spring, and the particular organisms living in each zone produce the remarkable range of colors we see.
The spring itself is enormous, stretching roughly 370 feet across. It sits within a large, colorful mound surrounded by terraces that make the entire feature even more dramatic. The center of the spring reaches temperatures around 160°F, creating an environment where very few forms of life can survive.
When we first saw Grand Prismatic, it was the colors that grabbed our attention. The deep blue center contrasted with the brilliant oranges, reds, yellows, and greens surrounding it. Even after seeing countless photographs of this famous Yellowstone landmark, standing beside it on the boardwalk was something completely different.
PRO Tip: The thermal features around Grand Prismatic are beautiful, but they are also extremely dangerous. Always stay on the designated boardwalk and trails. Never step off the path to get a closer photograph or a better view. Keep children close and make sure they understand the importance of staying on the boardwalk. Yellowstone’s thermal areas are fragile, and the water and ground around them can cause serious injury.
Midway Geyser Basin: Shrouded in Morning Mist, a Geothermal Wonderland
There are two ways to experience the beauty of Grand Prismatic Spring. The first is from the Midway Geyser Basin boardwalk, where you walk right alongside the thermal features. From this perspective, you’re almost at eye level with the spring, so you don’t get the sweeping view of its famous rings of color. Still, the experience is incredible. On some days, the blue and orange colors of Grand Prismatic seem to glow through the mist.
PRO Tip: Grand Prismatic is often shrouded in steam when the weather is cool. The dramatic difference between the temperature of the hot spring and the surrounding air creates clouds of mist above the water. If you’re hoping to photograph the brilliant colors, warmer weather and a little patience can make a big difference.
On a windy day, that steam can blow straight across the boardwalk. You can be walking along one minute with a clear view of the spring and the next find yourself completely surrounded by a cloud of steam. Many a ball cap has succumbed to the wind and steam here!
The boardwalk is wide enough for people to pass each other, but it can become crowded during the busiest summer months. Take your time, watch your footing, and don’t worry if the view changes from one moment to the next. The shifting steam is part of what makes Midway Geyser Basin so fascinating.
Turquoise and Opal Pool: Forgotten Jewels of Yellowstone’s Midway Geyser Basin
Grand Prismatic Spring may get most of the attention, but Turquoise Pool and Opal Pool are two beautiful features worth slowing down for as you continue along the boardwalk.
Turquoise Pool is the first of the two. It is relatively small compared with Grand Prismatic, but its striking blue color makes it hard to miss. The deep turquoise water creates a beautiful contrast with the surrounding thermal landscape and makes this a great spot for photographs.
A little farther along is Opal Pool. This smaller feature is actually a fountain-type geyser and can erupt periodically, sending water into the air. Its bright blue water and colorful surroundings make it another worthwhile stop along the Midway Geyser Basin boardwalk.
These two pools are easy to overlook when everyone is focused on Grand Prismatic Spring. We thought they were worth the extra few minutes, especially when the crowds around the larger spring made it difficult to stop and take everything in.
Fairy Falls Trailhead: The Best View of Grand Prismatic Spring
If you want to see Grand Prismatic Spring from above, the Grand Prismatic Spring Overlook is the place to go. The trail begins at the Fairy Falls Trailhead, located just south of Midway Geyser Basin.
The overlook trail is about 1.2 miles round trip and climbs roughly 105 feet. Most of the walk is relatively easy, although the final portion includes some uphill hiking and switchbacks. It is a manageable hike for many visitors, but those last few switchbacks made this Florida girl sweat a bit!
The overlook itself isn’t very large, and it can get crowded. When we visited, there were plenty of people waiting for their turn to see Grand Prismatic from above. Still, once you reach the platform and see the entire spring spread out below you, the crowds seem worth it.
From this vantage point, you can finally see the full scale of Grand Prismatic. The brilliant blue center is surrounded by bands of orange, yellow, and green, and the spring takes on a completely different appearance than it does from the boardwalk.
Keep in mind that weather can dramatically change the view. On cool mornings, steam may obscure much of the color. If you arrive and can’t see the brilliant colors you expected, don’t give up. The view can change quickly as the mist moves across the spring.
Continue Toward Fairy Falls
If you have more time, you can continue beyond the Grand Prismatic Overlook on the Fairy Falls Trail. The longer trail leads to Fairy Falls and offers opportunities to see additional scenery and wildlife along the way.
The trail also connects with other routes in the area. If you’re interested in exploring more of Yellowstone’s geothermal features, check out our guide to Lower Geyser Basin.
Final Thoughts on Midway Geyser Basin Yellowstone
Our visit to Midway Geyser Basin Yellowstone turned out to be one of those stops we won’t soon forget. We came to see Grand Prismatic Spring, but the entire boardwalk experience made the visit special. The brilliant colors, clouds of steam, and the sheer size of Excelsior Geyser gave us plenty to appreciate along the way.
If you have never visited Midway Geyser Basin, I highly recommend making time for it during your Yellowstone trip. Walk the boardwalk, take your time at each thermal feature, and, if you can, make the hike to the Grand Prismatic Overlook. Seeing the spring from above gives you a completely different perspective.
Grand Prismatic may be the star, but Excelsior Geyser, Turquoise Pool, Opal Pool, and the surrounding landscape are all part of what makes this little corner of Yellowstone so memorable.
For us, Midway Geyser Basin lived up to every bit of its reputation. The colors really are that incredible!
