June/July. Adivasi Colony is a community of Ambalakars living in huts of mud, coconut fronds and palmyrah leaves on the edge of Kodiakkarai village. Their traditional livelihood was the collection of non-timber forest products in the areas that are now the sanctuary. These practices are now prohibited but not fully eliminated. Many of these people catch fish and small prawns in the nearby mudflats and swamps. Some work as day labourers in the nearby salt pans. They have little interaction with other communities on the island. Chola Lighthouse is the remains of a brick and mortar lighthouse near Point Calimere said to have been built by the Cholas more than a thousand years ago. This structure was badly damaged by the 2004 Indian Ocean Tsunami but can still be seen in the intertidal zone near the British lighthouse. British Lighthouse is a tall operating lighthouse built by the British at the tip of Point Calemere in 1890 and can be seen at sea. Kodiakkarai Lighthouse is a tall modern aid to navigation located near Kodiakkarai Beach and is accessible to the public between 1500 - 1700hrs. This dominates the sanctuary and may be seen by seamen far at sea.
