Also referred to as ‘Trinco’ by many, this is a historic port city in the Northeast with one of the finest natural harbors in the world. The beaches here have very shallow waters which makes it possible to walk in the sea. This has made snorkeling, diving and swimming popular activities among visitors. As a way of enjoying the majesty of the sea without getting in, whale watching is starting to gain popularity in this area. There are historic landmarks such as the fort and temples (both Hindu and Buddhist) here. For many adventure enthusiasts, Pigeon Island which is offshore of the town Nilaveli would be a great place to visit.
