Princess Di Trail: Length - 8 miles
This advanced trail is tight, narrow, isolated and long. After a 2-mile climb and 1-mile descent on the Three Mile Canyon paved trail, trail users are treated to a great adventure that offers beautiful views of Eastern Summit County. Narrow, winding singletrack and tight switchbacks offer trail users a wild feeling...something not experienced much in the Park City area. If you plan to ride the whole trail, be prepared with water and food as the trail can be hot and exposed during the months of July and August. The trail can be used as an out and back or as a loop by connecting to the Rail Trail at Tollgate Canyon. You must use the I-80 overpass and ride through the culvert under the westbound lane in order to do this. The loop from the Promontory trailhead is approximately 14 miles in length.
Three Mile Canyon Trail: Length - 3 miles
This trail is paved and has a soft shoulder. It climbs several hundred feet within the first 2 miles and descends for the last mile to the beginning of Princess Di Trail. This is a great workout with burleys and baby joggers. The soft shoulder allows for easy travel for horses and the trail serves as great access to Princess Di Trail.

South Canyon Trail: Length - 5 miles
This trail begins just before the gatehouse at Promontory along the Three Mile Canyon Trail. The first 1/2-mile is a gravel road and turns into singletrack as it meanders along the hillside toward Brown's Canyon Road. This is an easy mountain bike ride with a few negotiable, technical and rocky sections. Users should keep an eye out for the Rocmon Trail that connects trail users from South Canyon to the Rail Trail. This makes for a great early and late season loop!

Parking: Please access the trail through the Promontory trailhead located along the Rail Trail.

Notes: Dogs should be cleaned up after, leashed and IN CONTROL at all times.
