Biosphere reserves play an important role in protecting Guatemala’s forests, watersheds, and animals. The Sierra de Las Minas Biosphere Reserve and Maya Biosphere Reserve are the largest and most significant reserves in Guatemala. They harbor endangered animals and the largest protected tropical forests in Meso-America. Reserves often contain other national parks and biotopes and can cover huge or small tracts of land. Visiting one of Guatemala’s reserves is an intimate experience with nature and a good opportunity to see huge trees, colorful birds, and picturesque volcanoes.
