Today it is the name of a tropical biosphere reserve covering 1.3 million acres of land along the central coast of the state.
The goal of the Biosphere Reserve is to preserve the flora, fauna and ecosystems of the area while satisfying the needs of the local population. In biosphere reserves, conservation is not conceived of as prohibiting use, but rather as the rational and long term, sustainable use of the resources.
Ka'an is made up of a wide variety of wetlands and coastal habitats:
tropical forest, low inundated forest, "cenotes" or
sink holes, low tropical forest, savanna, mangrove forest, coastal dunes,
reef lagoons, and coral reef.
With the tour guide you will motor through brackish (half salt, half fresh) water, float ancient Mayan trade water ways, view hidden Mayan ruins, and view exotic birds and other wild life.
Along the journey you are surrounded by birds, tall mangrove trees, orchids, bromeliads, termite mounds, fish and much more.
