There's no shortage of beaches to explore at Andaman Islands, but if you're looking for crystal clear coasts brimming with rich marine life, then North Bay Island is the place to go. Located on the southern parts of the mainland, this laid-back beach town's beauty extends to the deepest parts of its coastline. Explore its underwater reserve through this sea walk experience, which allows participants to set foot on the sandy seabeds of the island. Learn the basics before you try from a trained instructor and gear up with the waterproof glass helmet provided by the friendly staff. Plunge 6-7 meters into the sea and discover a diverse ecosystem of vibrant coral reefs, schools of fish, and other sea creatures. Walk down the pontoon and into the blue, where you can spend 20 minutes immersing yourself in the stunning scenery. Get your photos taken by one of the staff and make sure to strike creative poses for an even more memorable souvenir. Head back to the pontoon just in time for your ride back to the jetty.
