Damlataş Cave sits at the base of the promontory, a short walk from Cleopatra Beach. It was discovered in 1948 during blasting operations to create the harbour — the workers broke through into a chamber full of stalactites and stalagmites that had been forming for around 15,000 years.
The cave is not large, but it is visually striking: the formations are dense and varied, with orange and white stalactites hanging in clusters from the low ceiling. The air inside maintains a constant temperature of around 22 °C and humidity of 92–98%, with naturally elevated levels of carbon dioxide and radon. The cave became well known in Turkey for these atmospheric qualities, which are said to benefit people with respiratory conditions, particularly asthma. A daily early-morning session (typically 06:00–10:00) is reserved for people with asthma or bronchitis; the rest of the day the cave is open to general visitors.
The entrance is near the beach, and the visit takes around 20–30 minutes. It can be easily combined with time on Cleopatra Beach.
