This difficult 61.7-mile (99.2 km) route, which includes 2104 feet (641 metres) of elevation gain, offers a journey through Idaho's scenic backcountry, often providing sweeping vistas of the majestic West Teton Range and a notable Grand Teton westside vista.

Planning your ride on the Ashton-Tetonia Rail Trail Loop means preparing for a full day out. Parking is usually accessible at various points along the route, but it's always a good idea to check specific trailhead access before you go. Given the distance and duration, an early start is recommended, and carrying enough water and snacks is crucial, as amenities are limited once you're on the trail.
This rail trail conversion offers a unique cycling experience, blending the relatively flat grades of former railway lines with the challenge of a long-distance loop. The primary draw is undoubtedly the stunning backdrop of the Teton Range, making it a memorable ride for those who appreciate both a physical challenge and spectacular natural scenery in the Idaho-Wyoming border region.

The trail's surface is primarily packed gravel and dirt, so a mountain bike or a touring bike with tires at least 32mm wide is recommended. Road bikes are not suitable due to some rougher sections and occasional soft asphalt.
The Ashton-Tetonia Rail Trail Loop is generally considered easy, following gentle old railroad grades. However, cycling from Ashton to Tetonia involves a slight uphill climb of about 800 feet. There's also a 1.4-mile detour in the France-Drummond area that reroutes cyclists onto county roads, which can feature steeper, sometimes muddy, pitches.
You'll experience diverse scenery, including farm country, riparian areas, and aspen stands. Major highlights include constant views of the majestic Teton Mountains, especially from the Grand Teton westside vista and West Teton Range. You'll also cross three historic trestle bridges over Fall River, Conant Creek, and Bitch Creek, and pass by the historic Pillsbury Mills Elevator and Lamont Station.
While the trail itself is generally dog-friendly, specific rules regarding leashes and waste disposal may apply. Always keep your dog on a leash and be prepared to clean up after them. Check local regulations for any specific restrictions.
The trail is best enjoyed during the warmer months when the surface is dry and free of snow. Spring, summer, and fall offer pleasant conditions for cycling. Be aware that shade is limited along much of the trail, so adequate water and sun protection are advisable during sunny periods.
Generally, there are no specific permits or fees required to access the Ashton-Tetonia Rail Trail itself. However, if your route takes you into or near the Jedediah Smith Wilderness area, it's always wise to check with the Idaho Department of Parks and Recreation or the relevant forest service for any current regulations or fees, especially for overnight stays or specific activities.
Access points with parking are available in both Ashton and Tetonia, as well as at various points along the trail. Specific trailhead parking information can often be found on local tourism or park websites.
