Kalymnos

Kalymnos is a Greek island in the Dodecanese group in the South Aegean region, known for its maritime history and steep limestone cliffs. The island has a long tradition of sponge diving and a growing reputation as a premier sport-climbing destination.

Rock climbers come for extensive limestone crags and bolted routes concentrated around bays such as Massouri and the cliffs near Telendos; the island hosts thousands of sport routes of varying difficulty. Seaside towns such as Pothia provide ferry links, ports and local services, and small museums recount the sponge-diving heritage.

Kalymnos was inhabited in antiquity and developed a specialized sponge-diving economy over many centuries; its maritime culture shaped local architecture and trade. The island passed through Ottoman rule and, like other Dodecanese islands, became part of the modern Greek state after the 20th century.

Geographically the island sits in the Aegean Sea between Kos and Leros; the main harbour and settlement is Pothia, with regular ferry connections to other islands in the Dodecanese.

• Sponge heritage: Home to a long tradition of commercial sponge diving and still known locally for sponge workshops and museums.
• Climbing: Recognised internationally for sport climbing with thousands of bolted limestone routes on steep coastal cliffs, attracting climbers year-round.
