This trail is in Hart Canyon, at the site of a supposed UFO crash from back in the 40's. This is a ten mile one-way loop that takes you in and out of the Juniper trees, and along the slick rock shelves of the canyon. At the Eastern end of the loop is the Alien Monument where you will find a brief history of the site. Terrain variation is what makes this trail great, and will have something for everyone.

Access Info

Headed North on Hwy 550, turn right at MM 164 and stay to the left. Continue down the dirt road until you reach CR 2575, then turn left. At that intersection is a Natural Gas processing station, you can't miss it. Head up to the top of the hill, cross the cattle guard, make an immediate right down the one lane road to the trail head.

There’s dry sections but enough muddy sections to keep your tires caked for the whole ride. Needs another week or so.
