Charleston Peak loop in the Mount Charleston Wilderness portion of the Spring Mountains just NW of Las Vegas. It is such an obvious and natural peak loop (within 45 min of a major destination) that a lot of trail runners have done the loop (and blogged about the beauty of the Spring Mountains on the edge of the Mojave Desert). The legendary likes of Dave Mackey, Rickey Gates, & Karl Meltzer have all at various times mentioned running the beautiful Charleston Peak loop.
