Grand Prismatic Spring

Midway Geyser Basin, Yellowstone National Park

The Basics

One of the best ways to see Grand Prismatic Spring is on a Yellowstone Lower Loop tour, which might take you to the springs as well as other attractions like Norris Geyser Basin, Excelsior Geyser, and the Fountain Paint Pots in just one day. Once you arrive at Grand Prismatic, take a walk around the wooden boardwalk circling the spring and admire views of the colorful surface. Be warned, though, that the water itself is far too hot to touch. For the best view of the spring, take a short hike up one of the nearby hills (such as Midway Bluff) for a panoramic vantage point.

Lower Loop Van Tour from West Yellowstone: Grand Prismatic and Old Faithful
Aaron our tour master was knowledgeable, personable and knew where to be when. Bison sightings all over the park, near and far. Beautiful landscape, waterfalls, hot springs and Old Faithful doing her thing. What a beautiful National Park not to miss.

Lower Loop Van Tour from West Yellowstone: Grand Prismatic and Old Faithful
Our guide Aaron was great!!! Our pick up plans never materialized because the tour was not informed that they needed to pick us up!!! which caused a big problem but we got there. By hitching a ride. Aaron was the highlight of our tour. He was so knowledgeable, courteous and articulate. A joy to tour with him.

Lower Loop Van Tour from West Yellowstone: Grand Prismatic and Old Faithful
We had a wonderful experience. Our guide Sara was excellent. She took the time to explain not only the points of interest but the history and the geography behind the entire place. She gave us plenty of time to enjoy the sights and experiences at every stop. At the end she gave us great tips on dining and shopping. The lunch sandwich was excellent!
