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.
