Paraguayan Pantanal Nature Reserve

The Paraguayan Pantanal Nature Reserve is a 15,000 hectare reserve owned and managed by Guyra Paraguay. This part of the Pantanal, the largest wetland in the world, is one of the few sites in the world where the visitor may have a chance to find the three most-endangered species in Paraguay, “The Three Giants” – the Giant Armadillo, the Giant River Otter, and the Giant Anteater. The area surrounding the Río Negro (Black River) is a magnificent and pristine area full of gallery forests, palm forests, and extensive wetlands. While exploring these different habitats, visitors will easily be able to observe the abundant wildlife – aquatic birds, mammals, and reptiles – that are found in few other regions throughout the world.
Depending on the time of the year and level of the river, the Pantanal is home to huge quantities and large concentrations of aquatic birds: herons, cormorants, storks, ducks, screamers, and terns are abundant throughout the region. Reptiles are also common throughout the region, with snakes, lizards, Jacare Caiman, Iguana, and Black Tegu Lizard. This is also a good area for viewing mammals, with Black howler Monkey, Dusky titi Monkey, Marsh Deer, Gray Brocket Deer, Capybara, Giant River Otter, and, if your goal is to see a jaguar, “Los Tres Gigantes” offers the best opportunity.
“Los Tres Gigantes” Field Station
“Los Tres Gigantes” Field Station, inaugurated in 2008, has three rooms with space available for up to 12 people. Two of the rooms are shared with bunk beds for four lodgers in one and six in the other, each room with its own private bath. There is also a suite with private bath, couch, dresser, and king-sized bed. The biological station is powered by solar panels, and has kitchen facilities, a common area, and walking trails leading into the palm forests. Visitors may also take advantage of the canoes, horses, and fishing gear available at the lodge. Because of the large number of mosquitoes found in the area, the station is enclosed with metallic screens. Located along the banks of the Río Negro, “Los Tres Gigantes” is only accessible by boat and all food must be brought from the nearby town of Bahía Negra. The staff at the station prepares all of the meals and also acts as guides for the visitors.
