The Midway Geyser Basin at Yellowstone National Park may be small compared to the other thermal area in the park, but the effect is bigger because of the the most photographed, powerful thermal hot spring, the Grand Prismatic spring. The spectacular Grand Prismatic spring is the largest hot spring in the United States, and the third largest in the world. Its rainbow colored waters are what really make it so special. The cerulean hue in the center of the pool is pretty astonishing and the bright red, yellow and orange surround the edges make it even more spectacular. Expect crowd and try to visit around 10 am during the cooler months to avoid fog in the morning.
These photos are from our two day trip to Yellowstone National park in late August 2012.
Best Things To Do
- Midway Geyser Basin Trail: This short 0.8 mile loop boardwalk leads to two of the largest geothermal features in Yellowstone National Park, Grand Prismatic Spring & Excelsior Geyser. The trail begins from the Grand Prismatic Spring parking lot, then leads along the Firehole River to the bridge where you will get excellent views of the runoff from the Excelsior Geyser. If you go clockwise on the loop, the boardwalk takes you first to the Excelsior Geyser, then the spectacular Grand Prismatic Spring, next the Opal Pool, and finally, the Turquoise Pool
