There are two trails to choose from on Camelback Mountain!
Cholla Trail is an excellent choice for a moderate to somewhat difficult hike on the Camelback Mountain hiking trails! It takes about an 1.5 hours round-trip for hikers in good physical condition.
Echo Canyon is a difficult hike! Although it requires no harness or ropes, it feels at times more like a climb. That said, this trailhead is a ton of fun for the physically fit! Echo is something like an obstacle course and many of its regular hikers can make the round trip hike in about an hour.
