Il tunnel
★★★★★
(56)
The Tunnel Cave is a cave dive in very large spaces: its vault is 17 m high, impressive are the light effects when looking from the inside to the outside. There are also a couple of narrower tunnels reserved for those with a Cave patent.
The bottom of this cave consists of white pebbles, which in torchlight make this cave very bright. Rich in shrimp, porpoise crabs, stenopus and sometimes lobsters.
