Grand Prismatic Spring is probably the biggest and most colorful hot spring we visited in the park.
Unfortunately we did not have the time or energy to climb the hill to get the full overview effect of this amazing pool.
The Excelsior hot spring that we walked past to get to Prismatic was equally impressive.
It was very windy that day and a Ranger was collecting blown away hats in the pools with a long handled grabber. So hang on to your hats!
