These areas lie in parts of all seven Caribbean Sea coastal municipalities of the state, with the largest part being in eastern Felipe Carrillo Puerto Municipality, where the vast majority of Sian Ka'an Biosphere Reserve lies.
The reserve also includes some 23 known archaeological sites of the Maya civilization including Muyil. Remains of the Decauville railway Vigía Chico-Santa Cruz, which was operated from 1905 to 1932, can be found at several places.
Within the Amigos de Sian Ka'an project objectives are the identification, protection and management of additional areas with high biodiversity value as well as those critical for maintenance of the life cycles of endangered, threatened and migratory species in the Riviera Maya and providing environmental education through books, journals and pamphlets and giving technical assistance and training to Mayan communities working with ecotourism.
