Spend your first day surrounded by stunning natural beauty at Radhanagar Beach, known for its white sand and clear blue waters. Take a walk along the beach, swim in the sea, and soak up the sun. You can also enjoy water sports like snorkeling, scuba diving, and kayaking.
Explore the diverse marine life at Mahatma Gandhi Marine National Park. Take a glass-bottomed boat tour to view the coral reefs and colorful fish, or go snorkeling to get up close and personal with the marine life. Keep an eye out for endangered species like the dugong and water monitor lizard.
Visit the historic Cellular Jail, also known as Kala Pani, where Indian freedom fighters were imprisoned during the colonial era. See the Sound and Light Show in the evening for a dramatic retelling of the jail's history. Afterward, take a short boat ride to Ross Island, which was once the administrative headquarters of the British in the Andaman Islands.
End your trip with a trek through Mount Harriet National Park, home to a diverse range of flora and fauna. The park offers panoramic views of the surrounding islands and the Andaman Sea. If you're lucky, you might even spot some endemic bird species like the Andaman crake and Andaman woodpecker.
If you have more time, consider visiting more beaches like Elephant Beach and Kalapathar Beach. If you have less time, skip Ross Island and spend more time at other places. Plan your activities according to the weather, as some water sports might not be available during the monsoon season. Try the local seafood, especially the crab and prawn dishes. Pack sunscreen, insect repellent, and comfortable clothing for the trip.
