The Ayia Napa Sea Caves are a must-see along the stunning coastline at the edge of Ayia Napa. In addition to being great looking, they extend up to 80 meters underground and are only partially submerged, and can be explored on foot at low tide. This area is popular for snorkeling, diving and swimming. In clear pure water. Legend has it that caves were used by pirates to store their equipment and that cavernous tunnels, bridges and rock formations were an ideal hiding place for sailors.
