Lone Star Geyser

Lone Star Geyser is an impressive 12-foot cone geyser located along the Firehole River in Yellowstone National Park. Reachable via an easy 2.5-mile trail, it rewards hikers and cyclists with dramatic eruptions reaching up to 45 feet every three hours. The surrounding pine forest and scenic river setting make it one of the park's best backcountry thermal destinations.
