Mordogan, Turkey

Tucked into the Karaburun peninsula near Mordoğan, Ayıbalığı Cove is one of İzmir's quietest secrets. Unlike the sandy beaches most tourists chase, this bay is carved entirely out of rock, which somehow makes the water calmer and clearer than almost anywhere else nearby. Locals call it one of the five cleanest coves in İzmir, and once you see the color of the sea here, you won't argue.
