Midway Geyser Basin - Yellowstone National Park

Midway Geyser Basin is located between Madison and Old Faithful and well worth visiting. One of the epic highlights of Yellowstone National Park Grand Prismatic Spring can be found here along with Excelsior Geyser, and Opal Pool.

Midway Geyser Basin - Yellowstone National Park

A great half-mile boardwalk loop trail from the parking lot guides you past both Excelsior Geyser and Grand Prismatic Spring. 

This area has not always been known as Midway Geyser Basin in the past it was also called Egeria Spring, Excelsior Geyser Basin, and Hell's Half Acre. In 1871 it was called Half-way Group because it was between Lower and Upper Geyser Basins. 

This is one of the most popular thermal features in the park! You will want to be prepared for it to be crowded! 

Grand Prismatic Spring

Grand Prismatic Spring is 370 feet in diameter and more than 121 feet in depth.  It is the third-largest hot spring in the world and the largest in the United States

The deep blue pool is surrounded by rings of yellow and orange bacteria that create a prism effect. 

If you have seen photos of Yellowstone you can bet that a photo of Grand Prismatic Springs was included. 

It is worth noting that the signs on the road say Midway Geyser Basin, not Grand Prismatic Spring so it can be really easy to miss that this epic spot is part of the geyser basin.

Excelsior Geyser

Excelsior Geyser erupted on September 14, 1985, to the height of 55 feet and lasted 46 hours. The last known eruption occurred in 1888. 

At one time it was the largest geyser on earth. In the 1800s this geyser once exploded 300 feet high. It then remained inactive for 120 years. 

The deep blue pool now produces 4,000 gallons of water per minute into the Firehole River. The water flows down several colorful drainage channels into the Firehole River.

Opal Pool

Opal Pool is on the Midway Geyser Basin boardwalk right after Grand Prismatic Spring. 

This small pool is gorgeous especially in the bright sun. 

Turquoise Pool

The final pool along the boardwalk is the Turquoise Pool. One thing to know is when you walk past Turquoise Pool you will need to cross the crowds that are starting the one-way boardwalk.

It can get a bit busy and hectic in this area of the boardwalk. 

Travel Tips

If you are visiting during the summer you will want to be prepared to wait to get into the parking lot. It took us over 20 minutes to get into the parking lot during our last trip to the park. 

Later in the day, it looked like the line was even longer. 

You may have to circle the parking lot a few times to find a parking spot. Grand Prismatic Springs is one of the most photographed spots in the entire park. You can expect a large number of cars and tour buses to be packing the parking area.

Make sure to plan enough time to truly be able to enjoy the area. There are benches for sitting and relaxing to just soak in the view.

At times the steam coming off of Grand Prismatic can completely cloud in the area. You will want to have enough time to come back and view the area again if it is fogged in. 

Midway Geyser Basin is on the Lower Loop Road approximately 10.5 miles south of Madison on the west side of the road.
