This region is fed by a dense hydrological network integrated by the rivers Usumacinta, Lacantun, Jatate, Tzendales and Lacanja, among others; and by the lakes Miramar, Ocotal and Lacanja. It presents lacustrine bodies of karst nature and is a very important area in the capture of rainfall that acts as a recharge of underground aquifers.

It represents an ecosystem of high diversity and fragility; high evergreen forest, subperennifolia medium forest, mountain mesophilic forest and an extraordinary ecological importance for its lagoons and its biodiversity (within which there are endangered species, such as the curassow, the harpy eagle, the quetzal and the jaguar) .

Metzabok and Naha have an approximate area of 30% of the surface of the Lacandon Jungle. In them are settled small communities of the Lacandon ethnic group that keep alive cultural aspects such as their language, dress and traditions; and administer the tourism infrastructure.
