There are plenty of places to visit in the Andamans region. It depends on how many days you plan to spend there.
Port Blair, Havelock Islands and Neil Islands are the most common tourist circuits in Andamans. Most of the tourists to Andaman visit these three places. If adventure is on your mind, then the Rajiv Gandhi Water Sports Complex at Port Blair can serve you best. Havelock and Neil islands also offer lots of water sports activities including scuba diving and snorkeling. Some of the most popular spots for snorkeling and scuba diving in Andaman Islands are Mahatma Gandhi Marine National Park, North Bay beach, Radhanagar beach, Corbyn's Cove beach, Bharatpur beach and Avis Island near Mayabunder.
If you are looking for offbeat experience in Andaman, then I would suggest visiting Diglipur and Mayabunder. There are a few stunning beaches in Diglipur, such as Ramnagar, Kalipur and Lamiya Bay beach, which are largely devoid of tourists. If time permits, then pay a visit to the Barren Island, which houses India's only active volcano. The limestone caves at Baratang Islands is another interesting place to visit in Andaman. If interested in marine life, then you may visit the Marina Park Museum at Port Blair and the Mahatma Gandhi Marine National Park.
Here's a complete list of must visit places in Andaman. As I have previously stated, there is no dearth of places to visit in Andaman. It really depends on your trip duration as to how many places you can cover during your Andaman trip.
