Best for beginner divers, 3-4m, boat entry.
Lost Lake in the Rock Islands, Palau, offers shallow snorkelling in depths of 3 to 4 metres. The site is characterised by calm water and visibility ranging from 10 to 30 metres. Access is by boat only, and the site features an overhead environment including caves or swim-throughs. Due to the presence of an anoxic lower layer containing hydrogen sulfide, strict buoyancy control is required. Guided tours are available and recommended to navigate the overhead environment safely. Water temperatures remain consistent between 29 and 30 degrees Celsius throughout the year, making a rash guard sufficient for most visitors.
