THING TO DO
Lone Star Geyser Trail
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.
