Dive Site: Phosphorous Cave

About Phosphorous Cave

Phosphorous Cave is a captivating underwater cavern located along Turkey's Mediterranean coast. This region, known as the Turkish Riviera, offers a diverse array of diving experiences, from historic wrecks to intricate cave systems. The cave itself presents a unique topographical feature, where divers can explore an environment where the Mediterranean's clear waters meet dramatic rock formations. The dive typically involves a descent along a sheer wall, which can reach depths of around 30 meters. As you approach the cavern entrance, the light begins to change, creating an ethereal atmosphere. Inside the cave, divers can ascend into a semi-surfaced chamber often referred to as the "Turkish Bath," where the ceiling is open to the sky, allowing natural light to penetrate. This creates a striking visual effect as you break the surface within the cavern. While the primary attraction is the cave's structure, the surrounding waters support various marine life typical of the Mediterranean, including colorful fish, octopuses, and moray eels. Visibility in this region is generally excellent, often exceeding 30 meters, which enhances the exploration of both the cave and its adjacent reef areas. Due to the depth and the overhead environment, an Advanced Open Water certification is typically required for this dive. Liveaboard trips in the Marmaris and Fethiye areas commonly feature such cave dives, offering multiple opportunities to explore unique underwater landscapes.
