Things to do in Antiparos are limited as the island is very small and keeps a lower profile compared to the cosmopolitan style of neighboring Paros. Apart from swimming and hiking to close beaches, there are few things to do.
Over the last years, there is an effort to develop diving on Antiparos island. Actually the sea bottom around the island has interesting reefs and some old wrecks, which provide good diving spots. Actually many diving trips are organized to Antiparos from the popular resorts of Paros.
Also, you can practice windsurfing and kitesurfing in Pounda in Paros, just a tiny ferry ride from Chora.
