Key Dive Site Facts
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 Kaş, 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.

Dive Difficulty & Safety Guidelines
Experienced divers should prioritize thorough dive planning when approaching Besmi Island. Due to the potential for strong south-easterly currents, a good understanding of drift diving procedures and proper buoyancy control is crucial for safety. The site's archaeological remnants, including the shipwreck, are found at considerable depths, starting around 30 m (100 ft) and extending beyond 40 m (131 ft), requiring divers to possess appropriate certifications for deep diving. Always conduct dives with a reputable local dive center from Kaş, as they will have the most current knowledge of conditions and can provide guidance. Checking weather and sea conditions before departure is an essential step; wind conditions particularly impact the suitability of a dive.
