The Arch is a boat-access site off Zakynthos, Greece, featuring a diverse topography of reef, wall, cave, and cavern sections. Divers can explore depths ranging from 7 to 70 metres, with an average depth of 18 metres. Visibility typically spans 15 to 30 metres, and currents remain mild. A thermocline is often encountered below 25 metres, which can result in cooler water temperatures. Due to the presence of sharp coral and rock surfaces throughout the cave and cavern areas, buoyancy control is essential to avoid contact. This site is suited for intermediate divers who can manage depth profiles and navigate varied underwater structures.
