The dive

You descend along the wall of the first of two large rock pinnacles on a sand and pebble bottom and follow the wall over seagrass to the cave.

Profile and sections

You descend along the wall of the first of two large rock pinnacles on a sand and pebble bottom and follow the wall over seagrass to the cave. On the right lies a small grotto, on the left a siphon that brings you quickly up to ~-5 m, where you come out among shoals of damselfish. Lobsters, moray eels and large conger eels live in the cracks; one diver reports at least 30 m visibility.

The cave owes its name to the salt crystals on its walls, which form as seawater slowly evaporates.

Practical: only as a guided dive with a dive centre on the island; Tremiti Diving Center offers it. The AMP rates the dive easy and one dive report calls it perhaps the least demanding dive of the trip.

Depth and profile
Plan for -40 m (one tourism site); the AMP and two dive reports give max ~-25 m. The siphon takes you back up to ~-5 m.
Configuration
Dimensions of the cave and siphon not published; the centres dive it as a recreational dive. Ask the dive centre.
DPV: Not DPV-suitable
Scooters are banned in the AMP except for divers with a disability.
