AQUAMAN Ölüdeniz

Beneath the sheer limestone walls of Babadağ plunging directly into the sea, swimmers launch from the beach of Butterfly Valley into the Mediterranean. This dramatic coastal setting is the stage for AQUAMAN Ölüdeniz, an open water swimming event held along the shores of Ölüdeniz on the southwest coast of Turkey. Held in the mild days of October, the race immerses swimmers in warm Mediterranean waters beneath clear autumn skies. The sea offers exceptionally comfortable conditions for distance swimming along the open coastline. The flagship challenge is the 6-kilometer point-to-point marathon swim organized by Aquaman Open Water Swimming. Swimmers assemble at Butterfly Valley before charting an open sea line along towering headlands to the finish line at NO1 Beach Club in Ölüdeniz.

With a generous cut-off time of three hours and thirty minutes, the route offers swimmers plenty of time to find their rhythm as the towering coastline unfolds overhead. For swimmers seeking shorter distances, the event stages 3-kilometer, 2-kilometer, 1-kilometer, and 500-meter races based entirely around NO1 Beach Club. The 3-kilometer course loops through the open bay with a cut-off time of two and a half hours, starting and finishing right at the club's beach. Every participant in every category must tow an individual safety buoy, ensuring clear visibility along the sparkling Mediterranean water.

Butterfly Valley under the sheer cliffs of Mount Babadağ

Babadağ is a colossal limestone mountain rising 1,975 meters above the waves. Standing less than five kilometers from the water, its massif abuts the sea in imposing, rugged headlands. Ancient mariners knew these high cliffs as Mount Cragus, which forms the Seven Capes known locally as Yediburun, or the sacred promontory of Hiera Acra. The seaward face of the mountain falls away so abruptly that breakers churning far below can be glimpsed directly from the high ridges. Carved directly into the mountain base is Butterfly Valley, an impressive canyon stretching three to four kilometers inland between vertical rock walls 350 to 400 meters high. A freshwater creek runs straight through the canyon floor, bringing mountain water from a spring in the hillside village of Faralya all the way to the beach.

Deep inside the gorge, two permanent waterfalls plunge 60 meters down the rock face throughout the entire year. This secluded microclimate creates a lush sanctuary where entomologists have identified 105 distinct butterfly species across 15 families. Among them is the striking Jersey tiger butterfly, which congregates in large numbers between June and September. Stepping onto the beach on race morning, you can feel the cool breeze before taking the plunge into the open sea.

Gemile Island and the submerged Byzantine ruins

Along the surrounding coastline lies Gemile Island, known in earlier centuries as Aya Nikola. This rocky island is studded with the stone remains of early Christian and Byzantine churches built between the 5th and 11th centuries. Along the water's edge, ancient cistern ruins still line the shore, tracing the routines of seafaring settlements that once anchored in these quiet coves. Powerful earthquakes shook the region between 240 and 241 AD, causing parts of the coastal settlement to slide down into the sea. Today, these sunken stone foundations and harbor walls rest just two meters beneath the surface, clearly visible through the transparent water to anyone swimming or snorkeling above them.

The island is framed by wild anchorages such as Gemile Valley, where the freshwater Aladere stream cascades down in a waterfall toward the sea. About 4 km from the race area sits Soğuk Su Bay, a sheltered cove untouched by coastal roads that can only be reached by boat or via a forty-minute walking path leading down from a hillside church. Swimming along this shore feels like slipping into an ancient maritime crossroads along the salty Mediterranean.

The sheltered waters of Ölüdeniz and Kıdrak Nature Park

At Ölüdeniz, the Aegean Sea meets the Mediterranean in a broad sweep of blue. The name Ölüdeniz literally translates to "Dead Sea," an old moniker earned not from any lack of life, but because its sheltered waters remain remarkably calm and flat even when fierce storms batter the open coastline outside. The beach is composed of smooth pebbles, giving way immediately to crystalline waters filled with underwater caves and diverse marine species. Tucked beside the open bay lies the famous Ölüdeniz lagoon, an enclosed body of shallow water separated from the open sea and ringed by fragrant pine forests and steep mountain flanks. Strictly designated as a national nature reserve and part of a Special Environmental Protection Area, all construction here is completely prohibited, preserving the untamed coastal scenery.

Directly adjoining the coast is Ölüdeniz-Kıdrak Tabiat Parkı, a 25-hectare protected reserve bordered to the north by the Mediterranean Sea. The park encompasses the pebble expanse of Kıdrak Beach and provides well-maintained facilities for swimming and water sports beneath the shade of Mediterranean pine trees. Beyond the water, Ölüdeniz marks the starting point of the renowned Lycian Way Ultramarathon, which traces centuries-old paths.
