The Republic of Palau has protected 80% of its maritime area. Helen Reef and its small isolated island surrounded by turquoise water is one of the ecological treasures of this gigantic national reserve. Five rangers take shifts all year to watch on  the atoll, its reef and its fauna. Henaro Antonio is 24 years old and leads this happy team. The Taranauts had the chance to visit the island by his side. Follow the guide.
