Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Exploring the waters around the Prince Islands provides a distinct Marmara Sea experience, particularly at sites like At Mezarlisi. Here, divers encounter a pronounced thermocline, where warmer surface layers meet colder water around 10 meters (33 feet).
Descending past this often reveals a notable increase in visibility from approximately 20 meters (66 feet) downwards, enhancing the view of the underwater topography. The main feature is a very steep and extensive wall, dropping from about 7 meters to a maximum depth of 30 meters. This wall structure transitions into a sandy bottom at its base.
The site offers a compelling profile, beginning with the dramatic descent along the wall. As one progresses deeper, the cooler, clearer water opens up the view, revealing the contours of the extended wall before it flatters out into the sandy substrate.
This dual environment of a significant wall and a contrasting sandy bottom offers varied exploration opportunities, including an interesting deep hole with an entrance found at about 5 meters (16 feet).

Best Time to Dive
Optimal conditions for diving around the Prince Islands, especially for sites like At Mezarlisi, are crucial due to boat access limitations in windier weather. The period from February through October generally sees 'Excellent' dive scores, marked by lower wave heights and more favorable wind speeds. Specifically, rain levels are lowest from May through October, often below 2 mm, which contributes to overall better surface conditions. During these months, average air temperatures range from 16°C / 61°F in May, peaking around 25°C / 77°F in July and August, then gradually cooling to 18.5°C / 65°F in October. While specific water temperature data isn't consistently reported, the warmer air temperatures during these months typically coincide with more comfortable surface conditions for diving, potentially influencing visibility positively. Planning dives during calmer periods maximizes access to these wall and sandy bottom sites.

Dive Experience & Conditions
Beginning a dive here often involves an immediate descent onto the substantial wall structure. Divers typically start their downward journey from around 7 meters (23 feet), navigating the rapid drop. Around the 10-meter (33-foot) mark, you'll likely encounter a distinct thermocline where the water temperature shifts noticeably, sometimes quite abruptly. As you continue beyond 20 meters (66 feet), visibility generally improves, revealing clearer views of the deep rock face and its intricate details. The wall continues down to 30 meters, where it merges into a sandy bottom, offering a different ecological zone to explore. Close to the surface, at about 5 meters (16 feet), a deep hole provides an additional point of interest, suitable for exploration during the initial or final stages of the dive.
Dive Difficulty & Safety Guidelines
Accessing sites like At Mezarlisi hinges significantly on calm weather; dive boats operate only when surface conditions are settled, so always check forecasts. The steep, abrupt wall descent from around 7 meters (23 feet) to about 30 meters (100 feet) necessitates good buoyancy control and an awareness of depth limits. Divers should be prepared for a thermocline around 10 meters (33 feet), which can bring a sudden drop in water temperature. For those planning deeper segments of the wall or exploring the 30-meter mark, advanced training such as PADI Advanced Open Water Diver or PADI Deep Diver is highly recommended to manage potential narcosis and air consumption effectively in the cooler, deeper water. Safe diving practices, including monitoring dive computers and buddy checks, are essential.
