Dive Site Overview

Besmi Island captures the attention of divers with its compelling blend of natural reef beauty and significant historical artifacts. Situated southwest of KaÅŸ, it's a boat dive site known for cascading reefs that provide habitat for various species, including turtles and barracudas.

The major draw for many is the archaeological site on the island's north side, where a shipwreck, believed to date back to the ninth or 10th century, lies at a depth of around 40 m (131 ft). This vessel, possibly carrying olive oil and legumes from Gaza, was caught in a storm, leaving behind a scatter of 2,000-year-old amphorae and pithoi.

Divers exploring the site will find these ancient artifacts distributed across depths between 30 m and 60 m (100 ft and 200 ft). Average visibility here is generally good, often ranging from 20 m to 30 m (65 ft to 100 ft), reaching an average of 25 m (82 ft), allowing clear views of both the historical remnants and the vibrant marine life.
