Andaman & Nicobar Islands
Snorkel in the crystal-clear shallows of Elephant Beach (Havelock), Jolly Buoy Island, and Red Skin Island — pristine coral reef ecosystems accessible to non-swimmers in just 1–3 metres of water, teeming with clownfish (Nemo), parrotfish, sea turtles, and vibrant hard and soft corals.
Jolly Buoy Island (accessible from Port Blair) has among the Andamans' best snorkelling reefs — a permit is required (daily quota limited) and the island is closed May–September for reef recovery.
