Lone Star and Howard Eaton Trail Loop

While the route is named the Lone Star and Howard Eaton Trail Loop, mountain biking is primarily permitted on the designated Lone Star Geyser Bike Trail. Park regulations generally restrict bicycles to established public roads, parking areas, and specific designated routes. The Howard Eaton Trail, which connects to the Lone Star Geyser Trail, is largely a hiking trail where biking is not typically allowed on its full length.

The trail follows an old service road, featuring a mix of dirt and intermittent, patchy pavement. It is largely level with minimal elevation gain, making it suitable for most mountain bikers and even hand-cycles with mountain bike tires.

The primary highlight is the Lone Star Geyser, which erupts predictably every three hours, sending water 30–45 feet high for about 30 minutes. You can also spot Two Small Geysers and enjoy the scenic Lone Star Trail as it follows the Firehole River through a spruce-fir forest.

This trail is considered easy to moderately easy. Its largely level terrain and minimal elevation gain make it accessible for most riders, including beginners.
