The 2015 edition of the Kalymnos Rock Climbing guidebook is an all-new print edition of the guide with a free application for iOS and android devices. It is written by Aris Theodoropoulos, the author of five previous editions of the guidebook, who has been involved with the development of climbing on Kalymnos since it first started in 1999.
The new Kalymnos guide is a 448-page English language publication. It features approximately 2700 sport routes. The majority of photos and photo-topos are new, and in addition to the practical information about each crag (shade, exposure, approach etc), extras like GPS coordinates to each crag, have also been added.
