The underwater world also has its hermitage and desert. The Lučice Cave lies in the Lučice Cove, on the southeast shore of the island at a depth of only 5 m. It drops a further 15 m to a spacious chamber that leads off into two tunnels. The right side drops to 30 m, while the left drops to 44 m.
Anchoring is above the entrance to the cave, followed by descent to the cave and seabed and exploration of the left tunnel. On ascent, exploration of the less-demanding right tunnel is possible. Exploration at the entrance zone at 3 to 5 m is also ideal for a decompression stop.
Vertical caves are the harshest undersea habitat. The walls are bare as they are not exposed to currents, and algae are found closer to the surface where there is more sunlight. The only resident of this deserted cave is the leopard-spot goby, which is hard to find except in holes and crevices. Greater amberjacks also frequent the site.
