Mahatma Gandhi Marine National Park
This is a protected marine park known for beautiful reefs and quality scuba diving. The reefs were damaged in the 2004 tsunami and the park subsequently closed. Extent of damage is not known, but it is expected that the park will open again soon, if it hasn't already.
Flora and fauna
The general visitors permit you receive on arrival is good for here, but additional fees will apply when hiring a boat or arranging a dive trip since this is a National Park.
