There are two major attractions within the Chiapas portion of this rainforest, the El Chiflón Waterfall and the Gruta de San Francisco cave. El Chiflón is located 53 km west of Comitán de Domínguez formed by the San Vicente Rivers. The water fall from a height of over seventy meters surrounded by steeply sloped hills. El Chiflón is preceded by two smaller falls called Suspiro and Ala del Angel, which are about six meters in height. A cascade after it is called the Velo de Novia. The Gruta de San Francisco is located in the La Trinitaria municipality near the community of Santa María. The cave has a number of chambers filled with stalactites and stalagmites with capricious shapes, formed by the dripping of water through the cavity. These caves were considered sacred in the pre Hispanic period as passages to the underworld. The cave is also home to millions of bat which emerge at night to feed in the surrounding jungle.
