The Submarine Forests of the North Aegean: The Unique Red Corals of Ayvalık
Framed by historic olive groves along the Aegean coast of Balıkesir, the picturesque town of Ayvalık and its causeway-linked twin, Cunda (Alibey) Island, occupy an elite standing in global marine biology and scuba diving. Along with Portofino in Italy and select deep canyons off southern France, the Ayvalık Islands Nature Park is one of the only places in the entire Mediterranean where flourishing colonies of Precious Red Coral (Corallium rubrum) and golden gorgonian sea fans thrive. Sustained by strong undersea nutrient currents and rich plankton blooms, these delicate sea creatures build dense, vibrant underwater forests clinging to submerged pinnacles between 25 and 45 meters (80–150 feet) deep. Upgraded marine sanctuary regulations for the 2026 season make Ayvalık a prime pilgrimage for macro photographers, technical divers, and marine conservationists worldwide.
Among the archipelago’s 60 recognized dive spots around 22 islands, two offshore reefs reign supreme: Deli Mehmet and Kerbela Shallows. At Deli Mehmet, the coral walls begin at a depth of 27 meters. When struck by dive torch beams, the deep-water shadows ignite into a kaleidoscope of vivid ruby-red and luminous yellow fans that rival tropical Indo-Pacific reefs. The dense coral canopy shelters moray eels, spider crabs, colorful nudibranchs, and dusky groupers.
🤿 2026 Dive Season and Conservation Guidelines
The diving season in Ayvalık runs from May through late November. Because red coral grows at an agonizingly slow pace (only a few millimeters per year), divers must exercise perfect neutral buoyancy. Touching, finning near, or anchoring on the coral beds is strictly prohibited. Deep sites like Deli Mehmet require a minimum of PADI Advanced Open Water (AOWD) or CMAS 2-Star certification.
Legendary Deep Reefs: Kerbela, İlyasta and Melina
Ayvalık offers diverse underwater topography suited to varying skill sets. For experienced divers seeking exhilarating drift dives, Kerbela Reef is an absolute highlight. Starting at 19 meters and plunging vertically past 45 meters, this submerged mountain face is swept by nutrient-rich currents that allow gorgonian fans to reach impressive widths exceeding half a meter. Hanging suspended along the sheer drop while hunting amberjacks and bluefish streak past is an unforgettable experience.
For more relaxed, shallower dives, İlyasta (Güneş Island) and Melina Island offer sheltered bays at 10 to 18 meters depth. Here, ancient Byzantine amphora fragments litter the seafloor, octopuses peer from rocky crevices, and colorful sea anemones host juvenile fish. Night dives in these quiet shallows reveal bioluminescent plankton, hunting cuttlefish, and slumbering wrasses.
Island Life and Culture on Cunda
When the dive boats dock, Cunda Island’s cobblestone lanes and seaside promenades welcome you into a world of timeless Aegean romance:
- Cunda Historic Taş Kahve: A magnificent 19th-century neoclassical coffeehouse where divers gather under soaring ceilings for sage tea and mastic-infused Turkish coffee.
- Taksiyarhis Church (Rahmi M. Koç Museum): A painstakingly restored Greek Orthodox basilica housing antique scientific instruments, historic nautical models, and steam engines.
- Şeytan Sofrası (Devil’s Feast): A panoramic hilltop overlook offering legendary sunset vistas over the Ayvalık archipelago and the distant outline of Lesbos.
- Küçükköy Art Village: A historic stone village revitalized by contemporary art galleries, ceramic studios, and traditional Bosnian pastry bakeries.

Underwater Photography and Equipment Advice
Because red light wavelengths are completely absorbed below 10 meters depth, red corals appear dark olive or black without artificial illumination. Bringing high-powered video lights or dual external strobes is essential to reveal their natural ruby coloration. Macro enthusiasts with 60mm or 100mm lenses will discover tiny ghost shrimp and colorful sea slugs living among the coral polyp branches.
The North Aegean is generally a few degrees cooler than southern Mediterranean waters. While surface temperatures reach 24°C in summer, descending past the thermocline at 25 meters reveals waters of 17°C to 19°C (62–66°F). A 5mm or 7mm full wetsuit equipped with a hood is strongly recommended for comfortable diving.
