Cassidy Trail
The Cassidy Trail is a little-known but awesome ride. The trail is upper-intermediate technical, moderate aerobic. Trailhead is at 7200 feet, rising to 7900. The trail starts on Highway 12 in Red Canyon, and connects to the Casto Canyon and Losee Canyon trails. Ride options include out-and-back (to Braxton Point 5.5 miles round trip), loop with Losee Canyon (14 miles), or a loop with Casto Canyon (20 miles).

The Cassidy Trail is a lot like Thunder Mountain, which is located just on the other side of highway 12. This is probably the greatest ride you've never heard of. Done as a loop (or shuttle ride) up Cassidy then down Losee Canyon, it's a world-class ride.
The scenery is colorful limestone with a sprinkling of manzanita, cedar, long-leaf and bristlecone pine. Temperatures are warm but tolerable at mid-day in summer.

Getting there:
From US-89, drive 4.2 miles east on U-12 (towards Bryce Canyon National Park). Pass the Thunder Mountain trailhead, the Visitor's Center, and a campground. Watch for a turnoff into a well-hidden parking area on the left, signed "Red Canyon Trailhead." The Cassidy Trail begins at the northeast corner of the parking area. N 37° 44.111' W 112° 18.089'
