Lone Star Geyser Trail

The tan geyserite cone of Lone Star Geyser surrounded by snow.

This pleasant, partially paved trail follows an old service road beside the Firehole River to the geyser. Lone Star Geyser erupts up to 45 feet (13.7 m) from a 12-foot (3.6 m) cone approximately every three hours.

Safety notes: Cyclists must dismount at the end of the asphalt and walk the last few hundred feet.

Trailheads: 3.5 miles (5.6 km) south of Old Faithful Overpass, just beyond Kepler Cascades Parking Lot.

This is a 4.8-mile (7.7-kilometer) there-and-back trail that begins and ends at the same trailhead.
Pets Allowed
Entrance fees may apply, see Fees & Passes information.
This trail is located in the western part of the park, with the trailhead south of the Old Faithful developed area.
