Southern Faadhippolhu is defined by thilas and drift reefs spread across Lhaviyani Atoll, with boat access to every site. The reef pinnacles range from shallow crowns suitable for beginners through to current-swept walls demanding advanced skills. Reef Manta Ray and Whale Shark are observed across nearly every site, alongside multiple shark species including Blacktip Reef Shark, Silvertip Shark and Grey Reef Shark. Thilamaafushi House Reef stands apart as the only shore-accessible site, combining reef, wreck and muck diving in one.
