Coron island is a limestone island and the largest among the Calamian Group of Islands in Palawan and is inhabited by the Tagbanwa Tribe. Tourists are allowed to visit certain sites on the island but for the most part it is off limits to anyone from the outside.

The sacred inner lakes of the island have ‘watch-keepers’ to ensure there is no unauthorized access. There are about 1,800 Tagbanwa on Coron Island. The Tagbanwa are thought to have arrived in Coron from Borneo, which is about 500 miles away.
