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.
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.
