About 29 km west of Port Blair, lies the Mahatma Gandhi Marine National Park, stretching over an area of  281.5 sq km. It comprises open sea, creeks and 15 small and large islands. Tourists can view rare corals and underwater marine life through glass bottom boats and also go scuba diving and snorkeling. Private ferry operators give guided tours of the Mahatma Gandhi Marine National Park from Wandoor. Tourists are also allowed to spend two and a half hours in Jolly Buoy Island or Red Skin Island as part of the conducted tours. It is advisable to take a packed lunch (along with water) before heading to the park. The Mahatma Gandhi Marine National Park was created to protect marine life, especially sea turtles and corals.
