Eco-geeks will appreciate this boutique resort committed to the preservation of local flora and fauna, just a 20-minute speedboat ride from the coastal town of Mersing. The private island features 22-villas constructed in the traditional Malay-style, made with sustainably harvested tropical hard wood and glass. The island has eight beaches, a fresh water swimming pool and hilltop spa. After a day of exploring, fuel up at the retreat’s bar and restaurant serving fresh local produce. There’s also a non-profit study and dive center on-site. Rates start at RM750 (S$306) for a one-room jungle villa.
