Yellowstone National Park: Lone Star Geyser

A must-do hike in Yellowstone National Park, this easy 4.8-miler leads to Lone Star Geyser, a backcountry spout that shoots a 45-foot fountain of water into the air.

Rating

This easy, 4.8-mile out-and-back starts from the Kepler Cascades parking area. Check out these impressive cascades before following the paved Lone Star Trail to its namesake geyser. The trail crosses the Firehole River after half a mile and climbs gently through forest and several meadows. After 2.5 miles, the road ends near Lone Star Geyser, a dramatic (and fairly reliable) geyser that usually erupts every 3 hours, shooting water and steam 45 feet into the air. To calculate Lone Star’s next eruption, continue 250 feet farther to a logbook with the geyser’s recent eruption times. Relax and wait for the show, or turn around and follow the road back to the trailhead.
