The ultimate guide to mountain biking in a small state with a surprising number of great off-road cycling destinations. This book presents 37 of the best of these rides, from the nearly level rail trail beside the Delaware River to the challenging singletrack of the Round Valley Recreation Area. Each ride is accompanied by descriptive text and a detailed map containing all the information cyclists need to enjoy the ride. The map pages can be removed from the book and slipped into a standard bicycling map holder.
