Great reefs for diving, but check locally about the condition, as they were affected by the 2004 tsunami.
South Cinque Island is visitable with the general permit obtained on arrival in Port Blair.
Scuba Diving is the reason to come here...
There is no lodging at Cinque island, only at Wandoor, from where you take the boat to Cinque island. Try Anugama Resort at Wandoor.
