From Kalymnos, Rock Climbing Guidebook, by Aris Theodoropoulos: "The rock of Kalymnos is top-quality limestone. It is a little sharp in places, but free of choss. There is nothing monotonous about climbing on Kalymnos: there is a great variety of rock with slabs, delicate walls, pumpy routes with pockets and stalactites or tufas on overhanging rock and roofs... Many visitors have described the equipping of routes on Kalymnos as 'the epitome of sport climbing.'"
