Depths range up to 20 feet at the cove's mouth. Diving conditions are better outside the cove. Caves can be found around the cove's northwest point, and to a lesser extent to the south. The area to the left of the cove offers excellent night diving. The bottom outside the cove slopes to about 45 feet.
Visibility is generally poor inside the cove, but improves quickly outside.
The origin of the cove's name is uncertain, but sharks are no more common here than anywhere else on the island. Three Tables cove, located at the district's southern end, gets its name from the three or four flat sections of reef visible at low tide. Snorkeling is good around and just outside the tables area, and diving conditions improve farther out. Water depths near the tables average about 15 feet, and the best diving is at depths of 30 to 45 feet. Many ledges, arches, lava tubes and other features are found near and outside the tables.
