Ashton-Tetonia Trail

Trail Map

Description Suggest an Edit

The Ashton-Tetonia Trail officially opened in 2010 and extends nearly 30 miles between the towns of Ashton and Tetonia, Idaho. The trail occupies an abandoned rail spur once operated by Union Pacific (the Oregon Short Line). The trail includes five bridges and restored rail trestles. The gravel trail is managed by State of Idaho Parks and Recreation and is open to snowmobiles in winter when there is enough snow to groom the trail.

Mountain bikers and hikers might want to go from Ashton to Tetonia so that you can enjoy views of the Teton Moutains; however, this is slighly uphill (only 800 feet elevation gain over the course of the trail).

There's a 1.4-mile detour off the main rail line in the France-Drummond area in Fremont County to skirt private property where access has been denied. Take County Road 4400 E. (gravel road at Rt. 32) north to County 700 N. (2-track dirt) then head west to pick up the trail again. Note the snowmobile route takes a different detour in the Drummond-France area than non-motorized users.

Parking and Trail Access

While property ownership issues are being resolved in Ashton to build a trailhead, there is temporary trailhead parking farther east at Marysville. There is a parking lot at the trailhead in Tetonia.

I rode this trail from Ashton towards Tetonia on a HOT July day. Although I started before 9am the temperature was near triple digits by noon. Despite the heat, which necessitated turning around about halfway, this was a lovely ride. You can't beat the more

we rode from Tetonia to Ashton and back on a hot afternoon. The trail is wonderful and the bridges spectacular. The views of the Tetons on the way back are indeed well worth it. We did not find too many soft spots (except in the detour) and rode on our more

This ride is definitely worth doing from Ashton to Tetonia so the Tetons are always in your view. Trestle bridges are cool too. Over the length of the 30 miles, there's variation in the trail bed with some places being smoother/rougher than others. more
