Águas Quentes

Águas Quentes State Park (Parque Estadual de Águas Quentes) protects approximately 1,487 hectares of cerrado, gallery forest, and associated vegetation in the Guimarães plateau of central Mato Grosso, in the municipality of Santo Antônio do Leverger. ^[1] Located approximately 80 kilometers from Cuiabá, the park is centered on a cluster of natural thermal springs that have drawn visitors since the mid-twentieth century. Established by Decree 1.240 on 13 January 1978, it is the first protected area created in Mato Grosso and remains a unique combination of geothermal features and biologically rich savanna. The park's thermal waters, dramatic escarpments, and forested valleys have made it an important destination for nature-based tourism in the Cuiabá metropolitan region.

The park hosts cerrado and transitional forest fauna including maned wolf, giant anteater, tapir, brocket deer, pampas deer, tufted capuchin, black howler monkey, and several carnivores such as ocelot, jaguarundi, and crab-eating fox. Large terrestrial birds include red-legged seriemas and king vultures, while gallery forests shelter toucans, trogons, and a variety of tanagers. Raptors soar over the escarpments, and the streams support caimans, freshwater turtles, and characid fish. The proximity of cerrado and Amazonian influences produces an ecotonal avifauna with both savanna and forest species. Though small in size, Águas Quentes plays an important role in maintaining biodiversity and ecological connectivity in a region increasingly fragmented by agriculture.

Vegetation in the park includes cerrado sensu stricto, cerradão, campo rupestre on rocky outcrops, and dense gallery and seasonal forests along the escarpments and stream valleys. Characteristic cerrado trees include pequi, baru, sucupira, lobeira, and ipê-amarelo, while gallery forests harbor taller species such as jequitibá, copaíba, angico, figs, and buriti palms along watercourses. Orchids, bromeliads, and ferns thrive in humid microclimates near waterfalls and thermal springs. The mix of substrates, elevations, and microclimates supports exceptional plant diversity for an area of its size and reinforces the park's value for conservation in central Mato Grosso.

The park occupies part of the Guimarães plateau, a region of Proterozoic metasedimentary rocks including quartzites, schists, and phyllites. Deep fracture systems allow rainwater to infiltrate the rocks, circulate to great depths, and emerge as thermal springs at temperatures of 31 to 43 degrees Celsius. ^[1] The geothermal gradient, rather than volcanic activity, heats the water, making these springs a rare example of non-volcanic hot springs in interior South America. Thin, acidic soils cap the ridges, while deeper alluvium lines the valleys.

Águas Quentes has a tropical climate with distinct wet and dry seasons typical of central Mato Grosso. The rainy season runs from October to April, delivering most of the annual rainfall of about 1,400 to 1,700 millimeters in heavy afternoon storms. The dry season from May to September is warm and sunny with low humidity, especially in August and September when fire risk peaks. Daytime temperatures typically range from 28 to 34 degrees Celsius throughout the year, and even winter nights rarely drop below 15 degrees Celsius. The thermal springs maintain a steady temperature of 31 to 43°C regardless of season. Seasonal rainfall strongly influences the flow of streams, waterfalls, and forest phenology within the park.

Indigenous peoples of central Mato Grosso, including Bororo and neighboring groups, historically used the region for hunting, gathering, and as a spiritual landscape. The Portuguese entered the region in the eighteenth century during the Cuiabá gold rush, establishing settlements and ranches along the rivers. The thermal springs of Águas Quentes were known to locals long before formal tourism developed in the mid-twentieth century, when entrepreneurs built a hotel and bathhouses that drew visitors from Cuiabá and beyond. Conservation concerns led to the designation of the state park in 1978 that combined the geothermal attractions with protection of the surrounding cerrado and escarpment.

Águas Quentes State Park was created by Decree 1.240 of 13 January 1978, making it the first protected area established in Mato Grosso. ^[1] Management is the responsibility of the state environmental agency (SEMA-MT). A hotel and spa operated inside the park for decades, offering rustic accommodations and access to the thermal pools. Over time, infrastructure aged and operational difficulties led to periods of partial closure. State authorities, NGOs, and tourism partners have worked to modernize facilities and align them with the park's conservation objectives. Today the park continues to balance its role as a conservation unit with its identity as a historic geothermal destination.

The park's main attractions are its natural thermal pools, with waters maintained at 31 to 43°C, which draw visitors for bathing and relaxation in a forested setting. ^[1] Adjacent facilities historically included swimming pools fed by hot springs and bathhouses. Beyond the springs, short trails lead to forest viewpoints, small waterfalls, and stands of mature gallery forest where visitors can observe cerrado and transitional birdlife. Guided walks interpret the park's geology, ecology, and history. Wildlife observation is possible around dawn and dusk, particularly for monkeys and birds. The park is generally visited on day trips or short weekend stays from Cuiabá.

Águas Quentes is located about 80 kilometers from Cuiabá, with access via the MT-455 highway. ^[1] Historic infrastructure inside the park includes lodging and bathhouse facilities that have undergone periods of renovation; a hotel concession operates under a long-term agreement. Visitors should confirm current operating status with SEMA-MT before traveling. Cuiabá provides the nearest full range of services. Visitors should bring swimwear, water, sun protection, insect repellent, and sturdy footwear for forest walks. The park is typically open year-round, though access conditions vary with season.

Conservation efforts focus on protecting the thermal-spring system, maintaining forest cover on the escarpment, controlling invasive species, and minimizing the environmental footprint of tourism. SEMA-MT coordinates fire prevention, biodiversity monitoring, and visitor management, with support from federal agencies and research institutions. Restoring degraded areas within the park, particularly near former grazing zones, is a priority, as is reconciling historic hotel infrastructure with current environmental standards. Climate change poses emerging concerns about rainfall patterns, groundwater recharge, and the long-term stability of thermal springs. By integrating geothermal attractions with broader cerrado conservation goals, Águas Quentes aims to remain a model for sustainable nature-based tourism in Mato Grosso while protecting a geologically and biologically unique landscape.
