Kalymnos, known as the “Sponge Diver’s Island,” is a hidden gem that has remained largely untouched by mass tourism. The island’s main town, Pothia, features colorful houses and a lively harbor. Kalymnos is famous for its rock climbing opportunities, with numerous routes for climbers of all levels. The island’s crystal-clear waters make it an ideal place for diving and snorkeling. Vlychadia and Platis Yialos are among the island’s beautiful beaches, where you can relax and enjoy the serene surroundings.
