Helen Reef, Protected atoll in Hatohobei, Palau
Helen Reef is a protected atoll in Hatohobei covering around 163 square kilometers, made up of broad reef flats, a major channel system, and a small sand island within its bounds. The structure creates diverse habitats that support underwater and surface life.
A Spanish naval officer named Felipe Tompson recorded this location in 1773, calling it San Felix shoal during his expedition across the Pacific. The site has since become known as an important coral area in the region.
The Hatohobei community sees this reef as part of their ancestral waters, with local people directly involved in its protection. Residents of this region have deep ties to the sea and use traditional knowledge to help guard these waters.
Three permanent rangers operate from a basic station on Helen Island, conducting regular patrols to prevent unauthorized fishing. Visitors should be aware of the protected nature of the area and follow the rangers' instructions.
The reef is home to around 282 hard coral species and 530 reef fish species, and holds one of the largest Great-crested tern colonies in the Pacific. This seabird colony attracts thousands of birds each year for breeding.
