Andaman and Nicobar are a large group of nearly 600 islands in the Bay of Bengal. Though they are a part of India, geographically, they are closer to Myanmar and Thailand than to the Indian mainland. They are grouped here with Southern India. They were just north of the epicenter of the "Boxing Day" quake of 2004, and were the site of dozens of aftershocks. The Nicobars were badly hit the by the resulting tsunami, while the Andamans escaped with a few bruises. With the exception of Little Andaman Island and the Mahatma Gandhi Marine National Park, the rest of the tourist destinations are back up to speed.
