This bay was hiding place in the 17th century for pirates intercepting ships on their approach to Mergui harbour, and the allure of lost booty makes it an intriguing dive.

Local marine life includes Blue-ring Angelfish, Moorish Idols, Yellow-lined Snappers, and Bicolour and Bullhead Parrotfish, while blue-spotted ribbontail rays can be seen gliding over the coral substrate bottom.
