4 miles round trip, a very scenic hike, this trail winds up into a canyon known as Siphon Draw. It is possible to hike up the Flatiron (5.8 miles roundtrip), although it is not a designated, maintained trail all the way. It's advised that only experienced hikers in good shape attempt to hike to the top, as the climb is steep and difficult to follow. Allow at least five hours to the Flatiron and back.
