Andaman:Jolly Buoy Island 

 One among the most popular excursion from Port Blair is to Jolly Bouy Island from WANDOOR, 30km southwest to Port Blair. The long white sand beach here is littered with the dry, twisted trunks of trees torn up and flung down by annual cyclones. It is fringed not with palms but by dense forest. You should only snorkel here at high tide, as the corals are easily damaged when the water is shallow.
Visitors can enjoy the under water coral view through snorkelling, Scuba diving or glass bottom boat. As a standard trip, while getting down from the ship and transferring to the island through small boats, visitors will be taken through a ride and will be shown these under water corals through glass bottom, snorkelling is usually included in this trip. Though this is only for a very short duration . People willing to see more of these can hire a boat independently and enjoy.
The shades of the sea makes you fall in love with it. The place is immensely rich in fauna and corals. The underwater beauty of this place is divine. You will get to see many colorful fishes and corals.
