Bolivia maintains 123 protected areas covering approximately 170,000 square kilometers, representing roughly 17 percent of the country's total territory. The Sistema Nacional de Áreas Protegidas (SERNAP), established in 1998 under Law 1788, administers 22 national parks, 10 integrated management natural areas, 4 natural monuments, 3 wildlife reserves, and numerous regional and municipal reserves. This network spans elevations from 70 meters above sea level in the Amazon lowlands to over 6,500 meters in the Andean cordilleras. Bolivia's protected areas system encompasses one of the highest levels of biological diversity per square kilometer globally, including habitats ranging from high-altitude puna grasslands to tropical rainforest and dry Chaco scrubland.
Madidi National Park, established on September 21, 1995, covers 18,958 square kilometers in the departments of La Paz and Beni. The park extends from the Cordillera Real at elevations exceeding 6,000 meters down to the Amazon Basin at 200 meters elevation, creating ecological gradients that support extraordinary species diversity. Scientific surveys documented between 1,100 and 1,200 bird species in Madidi, representing approximately 11 percent of all bird species recorded worldwide. Mammal inventories recorded 272 species including jaguars, spectacled bears, giant otters, and both lowland and mountain tapirs. The park contains headwaters of the Tuichi, Hondoliayo, and Heath rivers, all tributaries of the Beni River system. Human settlement within park boundaries includes the Tacana, Ese Ejja, San José de Uchupiamonas, and Tsimane indigenous communities, who maintain traditional resource use rights under co-management agreements with SERNAP. Access points include the town of Rurrenabaque on the Beni River, which serves as the primary gateway for authorized tourism operators. Madidi adjoins the Pilón Lajas Biosphere Reserve and Indigenous Territory to the south, forming a continuous protected corridor exceeding 25,000 square kilometers.
Noel Kempff Mercado National Park received UNESCO World Heritage designation in 2000, recognizing both its ecological significance and relatively intact condition. The park covers 15,234 square kilometers in the department of Santa Cruz, positioned on the Huanchaca Plateau where the Brazilian Shield meets the Amazon Basin. The plateau rises abruptly from surrounding lowlands, creating escarpments with waterfalls including Arco Iris, Fawcett, and Federico Ahlfeld falls, the latter dropping approximately 80 meters. Vegetation zones transition from cerrado savanna on the plateau to evergreen rainforest in lower elevations, supporting documented populations of 139 mammal species, 620 bird species, and over 2,700 vascular plant species. The park name honors Noel Kempff Mercado, a Bolivian biologist killed by drug traffickers on this plateau in 1986 while conducting field research. Protection status improved significantly after 1996 when a debt-for-nature agreement between Bolivia, The Nature Conservancy, and several governments facilitated removal of logging operations and expansion of park boundaries. The park remains among South America's most remote protected areas, accessible primarily by chartered aircraft to the Flor de Oro and Los Fierros ranger stations, with no permanent road access.
Sajama National Park, established on August 2, 1939, holds status as Bolivia's first designated national park. The 1,002 square kilometer park surrounds Nevado Sajama, Bolivia's highest peak at 6,542 meters elevation. The Payachata volcanic group, including Parinacota and Pomerape peaks both exceeding 6,300 meters, marks the park's western boundary along the Chilean border. Vegetation consists primarily of puna grasslands with isolated patches of Polylepis tarapacana, a high-altitude tree species forming woodlands between 4,200 and 5,200 meters elevation, representing some of the world's highest-elevation forests. These Polylepis stands survived pre-Columbian and colonial-era harvesting because indigenous Aymara communities, particularly from Sajama village, maintained traditional management practices limiting extraction rates. Wildlife includes vicuñas, whose populations recovered from near-extinction in the 1960s to an estimated 3,500 individuals within park boundaries by 2010. The park contains geothermal features including hot springs at elevations above 4,000 meters, with water temperatures reaching 40 degrees Celsius. Archaeological sites within park boundaries include chullpas (funeral towers) constructed by Aymara ancestors between 1200 and 1450 CE. Road access from La Paz via Patacamaya and the town of Sajama on Route 4 takes approximately four hours, with the park headquarters located in Sajama village at 4,200 meters elevation.
Eduardo Avaroa Andean Fauna National Reserve, created in 1973, protects 7,147 square kilometers in the department of Potosí near the Chilean and Argentine borders. The reserve occupies the southwestern corner of the Altiplano at elevations between 4,200 and 5,400 meters, characterized by volcanic peaks, high-altitude lakes, and geothermal fields. Laguna Colorada, a shallow saline lake covering approximately 60 square kilometers, displays red and pink coloration derived from sediment pigmentation and algae concentrations, particularly Dunaliella salina. Three flamingo species congregate at Laguna Colorada: Andean flamingos, James's flamingos, and Chilean flamingos, with combined populations fluctuating between 30,000 and 80,000 individuals depending on water levels and seasonal conditions. Laguna Verde, positioned at the base of Volcán Licancabur at 4,350 meters elevation, contains high concentrations of magnesium carbonate, copper oxides, and arsenic compounds producing green coloration intensified by wind-driven suspension of sediments. The Sol de Mañana geothermal field features fumaroles, mud pots, and steam vents at 4,850 meters elevation, with subsurface temperatures exceeding 200 degrees Celsius. The reserve forms the most-visited protected area in Bolivia's national system, with approximately 100,000 annual visitors entering through the border town of Uyuni, typically as extensions of Salar de Uyuni tours. SERNAP established entrance stations at Laguna Colorada in 2000, implementing a 150 boliviano entrance fee for foreign visitors and 30 bolivianos for Bolivian nationals.
Amboró National Park covers 4,425 square kilometers in the department of Santa Cruz, positioned where the Amazon Basin, eastern Andes foothills, and northern Chaco converge. Park boundaries established in 1984 originally encompassed 1,800 square kilometers, expanding to 6,370 square kilometers in 1991 before contracting to current dimensions in 1995 following conflicts with colonist communities occupying northern sections. The park's elevational range from 300 to 3,200 meters creates habitat zones supporting over 3,000 plant species, 817 bird species, and 177 mammal species according to inventories conducted between 2000 and 2015. Cloud forests between 1,800 and 2,800 meters contain concentrations of endemic species including the Amboró Rocket Frog and multiple undescribed orchid species. The park contains headwaters of multiple river systems draining into the Río Grande and ultimately the Madera River basin. Access points include the towns of Buena Vista on the northern boundary, Samaipata to the south, and Comarapa to the west, with park guard stations at Macuñucú, Mataracú, and La Chonta. A 245 square kilometer buffer zone surrounds core park areas, permitting limited resource extraction by resident communities under management agreements. Road construction and petroleum exploration proposals within buffer zones generated disputes between SERNAP and Santa Cruz departmental government between 2005 and 2018, resulting in legal injunctions preventing development in several contested sectors.
