The small island of Kalymnos offers rock climbing throughout the whole year although summer can be very hot and the winter weather is a little predictable. April and May is usually considered to be the best time for rock climbing and bouldering.
Rock climbing on Kalymnos is as recent at 1996 when Italian climbers discovered Kalymnos as a climbers paradise. The island offers a variety of numerous lime stone rocks with different kinds of difficult degrees. The rock climbing is never monotonous as there are routes involving delicate moves or athletic routes on overhangs and roves with holes and stalagmites.
Rock climbing on Kalymnos is still rather unknown at an international level and therefore you will not find the usual crowds and queues which are typical on the famous crags.
