Climbing conditions in Leonidio are ideal for winter climbing, as the concave red cliff above the town acts as a natural shield against bad weather. The best period for climbing in Leonidio is November to April, though some crags higher up in the hills are good for climbing even on hot spring, fall or summer days.
The vast majority of climbing routes in Leonidio are relatively new. Many still require thorough cleaning of loose rock and traffic to improve. Pieces still break off, so helmets are strongly recommended.
