Best Outdoor Activities in Kalymnos, Greece

Kalymnos is world-renowned for rock climbing and offers diverse outdoor opportunities; no winter sports available on island.

Many single pitch routes are quite long (more than 30m), so an 80m rope is considered ideal, though climbers report a 60m rope can work if you're careful to knot the end.
2/3 of all accidents in Kalymnos involve lowering a climber off the end of the rope without a knot—always ensure you have a knot at the end of your rope.
Most people rent scooters to get around, though many rental places deem licenses optional—it's advisable to know how to drive one.
Unlike most of Greece, the tap water on Kalymnos is not drinkable and is too salty to just be boiled; there are free water stations in the towns where you can fill up water bottles.
While Kalymnos has a mild and sunny winter perfect for climbing on sunnier routes, tourism in the region tends to shut down during winter months, making accommodation sparser and restaurants often close.
You can dive with wild dolphins and tuna, barracudas and other marine predators; fish farms in the area made them local residents and friendly to scuba divers, though you should not feed them as they are still wild animals.
