It was longer than I had prepared for and there were a lot of ATVs, but it was a beautiful hike and fairly doable for a non-hiker.Dale Swensen4 years agooff road drivingThe overview for this trail is a little inaccurate. Although it is used by mountain bikers, it is mainly used by ATV's, pickups, & SUV's. If you plan on mountain biking be prepared for a lot of ATV riders. It is a nice scenic trail with the highlight being a huge granite monument to Old Ephraim (A giant grizzly bear that roamed the area in the early 20th century) The monument is near the spot where he was finally killed. Most of the natives of Cache Valley know the story of Old Ephraim. For a while his skull was in the Smithsonian, but a few years ago it was brought back to USU where they have it on display.
