Lumba Lumba Diving Centre is a PADI 5 Star dive resort on Gapang Beach, Pulau Weh, run by Dutch and Indonesian management since 1998. The centre pairs a relaxed, family atmosphere with a professional setup: PADI courses, fun dives, Nitrox, equipment rental and repair, and rooms a short walk from the water.

Weh's volcanic sites ring the island, so sheltered diving is available in every season. Expect current-swept pinnacles, an unusual density of moray eels, schooling fish and the occasional passing pelagic. Staff speak English, Dutch, Indonesian, German and French, and the centre holds a 4.8 rating from about 300 reviews.
