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.

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.

    We stayed at the back country campsite, about .25 past the geyser in August 2016. We started at 9pm in the rain, WOOT. The site was nice with firm ground for tent stakes, a bear pole to hang food (all back country sites have this), a fire pit and a toilet with a great view (most sites have these). A stream runs at the back of the site, with some geothermal spots. There are plenty of logs set up for seating under the bear pole area. Nice back country site, close to the geyser, but understand it’s easy access. We stayed at this site a few years back as well and got in early enough to make our boil in the bag dinners and head back to the geyser for dinner and a show.
