There are many caves in Kalymnos. However, the cave located in the area Kefala has the best access for the public. You can start by car from the monastery of Agia Ekaterini heading to the south-west and after 2km you will have to hike for 10 minutes, which is totally worth it, because the view of the cave is breathtaking. The narrow path that is either uphill or downhill constitutes a route with a total duration of 20 minutes that will bring you very close to the impressive stalagmites and stalactites. Certain parts of the cave are lightened creating an evocative atmosphere.
