The Railroad Right-of-Way Trail winds through the pristine wilderness of Idaho's Targhee National Forest. The sprawling forest is a unit of the even larger Caribou-Targhee National Forest, which borders famous Yellowstone and Grand Teton National Parks.

Built on a former railroad corridor that once provided tourist access from Idaho Falls, Idaho, to West Yellowstone, Montana, the trail parallels Warm River for a few miles from its south trailhead at Warm Springs Campground. About 3 miles north of the campground, a short tunnel—original to the railroad—leads through a steep piece of terrain. Unfortunately, the tunnel suffered a cave-in in 2008, so access is prohibited. The trail has been rerouted just to the east, providing closer views of the Warm River.

       Ive ridden this trail twice in its entirety. The trail is listed as 38 miles but if you start or end in West Yellowstone (and you should) your ride is going to end up being 46 miles. I would personally classify this route as a blue. The upper section is rocky and the rail trail itself is soft and often rutted. Parts of it are easy but there's a big difference between this section of rail trail and the Ashton to Tetonia trail to the south (which is far easier).

      It's an awesome adventure and I love it. It's not for everyone though and bear spray is a good idea.
