Less than three years after it was established, Arginonta Valley (particularly the main sector, which stays in the shade all day), is already one of the island’s most popular crags. Opposite the eye-popping, south-facing red cliffs over Arginonta village, the Arginonta Valley cliff seemed less impressive, camouflaged as it was under a thick layer of dry, woody shrubs. But when an EU grant funding the maintenance of 300 existing routes and the opening of 100 new routes was implemented in 2015/16, the time was ripe for extensive gardening and cleaning of loose rock to reveal a beautiful cliff underneath. The first 50 routes were funded by the EU grant; the remaining routes, which continue to be developed, are funded in large part by proceeds from the sale of this guidebook. Arginonta Valley satisfies some of the most important requirements for Kalymnos climbing: shade almost all day long; a short and easy approach; well-protected routes; and a wide range of difficulty levels, with quite a few routes in the easier and mid-grades.
CLIMBING: Varied, on slabs full of good holds and horizontal streaks, vertical walls with small holds and juggy bulges, but also steep overhangs with jugs and some colonettes. Development is ongoing: very recently (2018) new routes were added to Rock n Roll Cave, and a brand-new sub-sector, Comic Tree, was also established a bit further uphill.
