Kimolistes are volunteers that do many things in the island. They host outdoor cinemas at the castle and at some of the beaches. We were lucky to watch a movie inside the castle one night during our visit. The Kimolistes also maintain open-air libraries with books in many languages. You can find these free libraries in several places around the island, at Chorio and Prassa beach. It is okay to take a book and return it later.
At Prassa Beach, the Kimolistes provide kids toys in a large wooden box. Kids (and adults) can use the beach toys, which are things like balls and rackets, pails, etc, and return them at the end of the day. They also organise hiking excursions around the island and preserve the hiking paths for everyone to use.
