About the trip

Witness the Magic of a Backcountry Geyser

Today will be spent taking a pleasant five-mile stroll along the Firehole River to reach a magical backcountry thermal feature: Lone Star Geyser. This cone geyser is 12 feet tall and regularly erupts up to 45 feet! When we arrive at the geyser, we'll have a picnic lunch and wait for an eruption. Once we've enjoyed the show, we'll make our way back along the same path.

On the full-day tour, we can add on a trip to Old Faithful and explore the treasures of the Upper Geyser Basin.
