It's hiking with a welcome twist: no tandem driving, no dropping off a car at the end of the trail-and no turning around to hike back the way you came. Bruce Grubbs has selected the best existing loop trails and stitched together segments of other trails to form new loops. This is a guide of tremendous variety. You have your pick of terrain: desert, canyon, mountain, or forest. There are hikes along old pioneer trails, through volcanic fields, and past petroglyph views. To top it off, you'll often hike through several different life zones on the same trail-Grubbs is your best guide for understanding these too.Grubbs, Bruce is the author of 'Best Loop Hikes Arizona', published 2005 under ISBN 9780898869774 and ISBN 0898869773.
