Best Climbs Phoenix Arizona is the next installment in the Best Climbs series from Falcon, appealing specifically to traveling climbers and local climbers who wanted to be directed toward the best local climbing. Although the Best Climbs guides feature routes of all grades, the emphasis is on moderate routes in the 5.6 to 5.10 range. The book will include 150-200 featured routes. Each section will include climbing area trivia and history in the form of short "callouts," but the primary focus will be on the route selection and descriptions themselves. All routes will be shown clearly on detailed color photo topos, alongside stunning action photos and a contemporary, exciting design.
