In the course of time, as diving technology was developing, all known diving methods have been applied. There are still some locals who practice this profession up to this day, being the last remaining in Greece.

Snorkelling is the easiest way to approach the underwater environment. Anyone can enjoy the wonders of the sea, solely equipped with a deep breath and simple equipment, such as a mask, a snorkel, flippers and perhaps a diving suit. In scuba diving, the diver carries pressurized air in bottles, thus obtaining great freedom of movement underwater.

Scuba diving, however, is legal only in specific locations in Greece, for the protection of antiquities. In Kalymnos there is a wide area where anyone can dive, either through a diving center or independently, provided they possess the equipment and know-how.

There are diving centers in Kalymnos where even the amateur can dive safely in shallow waters under the constant supervision of experienced trainers.

The Kalymnos State School of Diving is the only diving school in Greece which is officially recognized by the state. It was founded in 1956 in order to train sponge divers and has been in operation ever since under the superintendence of the Ministry of Mercantile Marine.

Ever since 2004, a Diving Festival takes place in Kalymnos once a year. The area where diving is allowed is on the southeast part of Kalymnos and stretches from “Liani Pounta” bay to “Pithari” bay.

It is the biggest diving area and covers shoreline of 12 km in a 500 meter wide zone and up to the 40-meter contour line. It can be accessed by road through Vlyhadia, Therma and cape Kefala.

Organized diving centers operate in Pothia and Vlyhadia. Equipment is supplied and lessons are given for beginners and advanced.
