Mambetron is a north Kri house reef in Raja Ampat where the reef starts at the homestay door and then drops into deep blue a short swim offshore. It is a classic easy-access coral reef for snorkeling, relaxed scuba, and low-stress wildlife watching, with bigger animals sometimes passing through the blue beyond the reef line.
