Route Description for Lone Star Geyser Trail

The Lone Star Geyser Trail is a wonderful hike in Yellowstone National Park. This trail is used by both day-hikers and cyclists. When hiking, remain aware of your surroundings and allow folks on bikes to pass you by. In the summer, this trail can be buggy. If you are visiting in late June or early July, bring along some bug repellent or wear long layers to deter the mosquitoes.

The Lone Star Geyser is not a challenging or particularly adventurous trail, but it makes a fantastic, family-friendly outing. This route is wheelchair-accessible, stroller-friendly, and do-able for hikers of all ages. The Lone Star Geyser itself is an impressive, 4 m geyser that erupts approximately every three hours, shooting scalding-hot water 14 m into the air.

Beginning at the Lone Star Trailhead, follow the paved path along the Firehole River. Approximately 1.4 km in, look for the two small geysers on the right side of the path. 2.7 km from the trailhead, the path will split. Stay right at the divide to hike the last 1.3 km to the Lone Star Geyser.
