Chetlat Atoll Outer Reef

Chetlat is the northernmost inhabited island in Lakshadweep and one of the rarest dive destinations in the archipelago. Its outer reef has never been subject to commercial dive traffic — the island has no resort infrastructure, no organised dive operator, and access requires both a Lakshadweep Administration permit and a separately arranged government vessel. The reef flat is a time-capsule: near-complete hard coral cover on the crest, undisturbed sand channels feeding into a lagoon that still holds hectares of intact seagrass where green turtles feed. The outer wall drops from 8 m to beyond 40 m and retains large gorgonian colonies at 25 m that were bleached out on more visited atolls during the 2016 event but appear to have recovered here. Reef shark numbers — grey reef and blacktip — are noticeably higher than at any other Lakshadweep site, possibly because fishing pressure has been lower. Research-grade diving only; no dive services on the island. Serious divers with their own equipment and safety cover can arrange permits through the Lakshadweep Administration in Kavaratti.
