It's found in the southwestern part of the Montes Azules Integral Biosphere Reserve, at an elevation of about 300 meters above sea level. It is surrounded by low mountains 600 to 1000 meters in elevation. The area receives between 1500 and 2000 milimeters of rain annually, with a temperature averaging around 22 to 24 degrees Centigrade. This translates to a humid, tropical climate, though here it is a little drier and fresher than in bordering areas. The primary vegetation is classified as broadleaf evergreen high forest, with the canopy soaring to 40 to 70 meters high.
Visitors are always very impressed by the vegetation.
Those wanting to do more studies on what they can see on this trip can do so in San Crist bal, where there is an institute for post-graduate studies, called the Colegio de la Frontera Sur. This institute has scientific information gathered in the Selva Lacandona since 1971. It also maintains a special study of the Montes Azules Biosphere Reserve, resulting in the collection of the scientific names of plants and animals there. Besides natural attractions, the lake has historical and cultural values. Among these is the archeological site on Lacam Tun Island, where one finds remains dating from Late Preclasic Maya, to Lacandon-Chol Conquest times, at the end of the 16th century.
