Kalymnos: The Island of Sponge Divers and Rock Climbers
Kalymnos is an island of rugged verticality and deep maritime soul. Traditionally known as the home of the world’s most courageous sponge divers, it has transformed in the 21st century into a global mecca for rock climbing. In 2026, Kalymnos offers a rare blend of adrenaline-fueled adventure and old-world Greek tradition. With its dramatic limestone cliffs, hidden fjords, and a population that remains deeply connected to the sea, it is the perfect destination for those who want a holiday that is both physically challenging and culturally authentic.
Things to know about Kalymnos
Geographically, Kalymnos is located in the southeastern Aegean, between Leros and Kos. Its landscape is characterized by steep, barren mountains that drop into deep blue waters. Historically, the island’s economy was built on the dangerous trade of natural sponge harvesting, which took Kalymnian sailors across the Mediterranean. An ideal trip length is 5-6 days. It is famous for its 3,000+ climbing routes, its world-class natural sponges, and the fjord of Vathy. The local culture is fiercely independent, with a unique dialect and a culinary tradition that emphasizes seafood and mountain herbs.
