The Andaman Islands are an archipelago in India's Bay of Bengal. These roughly 300 islands are known for their palm-lined, white-sand beaches, mangroves and rainforested interiors. Surrounded with coral reefs that support marine life including sharks and rays, they're destinations for scuba diving and snorkeling. They're also popular for water skiing, windsurfing and fishing. Oceanside camping and hiking is possible on some islands.
