About this site

Minerva's Ledge lies off Henry Lawrence Island, part of the Ritchie's Archipelago in the Andaman and Nicobar Islands of India, east of the main Andaman group. Dive operators based out of Havelock Island commonly run boat trips out to sites around this archipelago. The reef here tops out at around 18 metres and is rated a beginner dive, though the current can run strong. Expect company from barracuda, eagle rays, fusiliers, grouper, snapper, trevally, tuna, unicornfish, and surgeonfish, along with humphead wrasse cruising the reef. Divers have also reported a tiger shark passing through on occasion.
