This basin is home to two of the largest geothermal features in Yellowstone: Grand Prismatic Spring & Exelsior Geyser. Midway Geyser Basin is much smaller than the other basins found alongside the Firehole River. Despite its small size, it contains two large features: the 200-by-300-foot-wide Excelsior Geyser which pours over 4,000 gallons per minute into the Firehole River and the 370-foot-wide and 121-foot-deep Grand Prismatic Spring, which is the largest hot spring in Yellowstone. Midway Geyser Basin is located about half-way between the Madison and Old Faithful regions of Yellowstone National Park. From the parking lot, take the trail south and cross the Firehole River. You will see several streams of steaming water pouring from the terrace above into the Firehole River.

The grand Grand Prismatic Spring is certainly one of the most deserve to see in the Yellowstone. However, It's too large to see the whole prism besides it. I suggest to hike both this trail and the other trail going to the mountain besides the prism and see it from above.

Nice easy trail with several views but noticed some people not paying attention and nearly pushed some people off the boardwalk. Crowded so go early.

As everything is in Yellowstone, very congested, but this was a very cool site. There is also an observation point nearby that's over 2 miles round-trip

Unbelievable!! The grand prismatic geyser is by far my favorite and a must see! The color variation is spectacular.

Flat walk.. very beautiful and multicolored pools that make this spot at the top on my must see places when I'm in Yellowstone

Great set of pools. You need to stop here on your trip. The grand prismatic gets a little steamy and hard to see, but wait for a gust and the colors get uncovered.

The Midway Geyser Basin star is the Grand Prismatic Spring, a huge chromatic-colored spring which looks like an eye from above and featured in a lot of post-cards. Early that morning, the area was halfway shrouded in mists, so we couldn’t see the blue and green colors very well. The mist was eerie as we crossed the bridge over the Firehole River and up the boardwalk past Excelsior Geyser, which showed a past explosion that moved much rock and blasted a hole in the earth, one of the huge eruptions in the Caldera. Experts think that this spot will erupt again, causing a catastrophic event in the future. Trace evidence shows three eruptions have occurred in the past 2 million years, every 600,000 years. In fact, there is a huge pocket of molten magma under the Caldera, and the area has risen due to the pressure build-up, but no one knows when the next eruption will occur. Yellowstone Lake itself is migrating southward because the north end of the lake is pushing upward. You can feel the earth move as you walk around the boardwalk. Later in our trip we again stopped at Midway Geyser Basin. On the bridge crossing the Firehole River, we spied a huge buck at the top of a cliff across the road. It was the Hartford Insurance logo picture against the sky. One trick we learned was to cross the street and scale the hill to the top for a real treat. The Grand Prismatic Spring is breathtaking in its blue-green splendor from this vantage point; this is the spot for the best view. Down below, we once again took the stroll around the boardwalk and the bacterial mats really stood out. DON’T miss it!

Ok walk on a boardwalk, usually very busy & actually is not the best way to see Grand Prismatic spring, but worth the walk if you have the time!

Went here with family years ago and loved it! Could spend so much time admiring the hot springs! So beautiful and so unique! This basin has one of the biggest and most beautiful hot springs (Grand Prismatic)! Gets very crowded...so patience is needed!

Here are two things that the above description seem to lack:
1. This is a heavily used area. If you're planning to visit June - August finding a parking spot will most likely be challenging. Be prepared to encounter a lot of people.
2. It's worth it for this reason: GRAND PRISMATIC SPRING. One of the most colorful displays of nature in the entire world. You must see this if you're in Yellowstone.

Easy walk around one of the world's biggest hot tubs. Very colorful. Be patient though because it gets crowded with tourists.

Very pretty!

Small trail but what a huge impact! This was my most favorite spots in Yellowstone, Grand Prismatic Springs is breathtaking. I would suggest going to the Fairy Falls trail to hike up the Grand Prismatic overlook.

Good time

Like most "trails" in Yellowstone, this is an easy to use boardwalk. Be prepared for lots of people, but it's well worth it. Highlight here is Grand Prismatic Lake, which is absolutely amazing. The colors are brilliant, so much though that it's almost supernatural.

Sadly, it was cloudy and snowing sulfer when we visited here, but it still managed to be fascinating.

Midway Geyser Basin is home to Grand Prismatic Spring, the largest hot spring in Yellowstone. Easy 1/2 mile walk along a set of boardwalks.

Midway Geyser Basin contains the Grand Prismatic Spring, Yellowstone's largest hot spring, and probably the most colorful. A 1/2 mile boardwalk takes you through the geysers, and across the Firehole River. Easy walking.
