Parque Nacional das Emas (ICMBio-Instituto Chico Mendes de Conservação da Biodivers

A protected expanse of Brazil’s Cerrado

Emas National Park protects one of the largest remaining areas of Cerrado savanna in southwestern Goiás, near the border with Mato Grosso do Sul. The landscape is more varied than the word “savanna” suggests: the federal conservation agency ICMBio describes open grasslands, scrubby fields, palm-lined wetlands known as veredas and gallery forests along streams. Chapadões and broad horizons give the park its open character, while rivers and wooded corridors create different habitats across the protected area.

The park was created in 1961 and today covers about 132,788 hectares according to ICMBio’s unit profile. It extends across parts of Mineiros and Chapadão do Céu in Goiás and Costa Rica in Mato Grosso do Sul. UNESCO inscribed Emas in 2001 as part of the Cerrado Protected Areas, together with Chapada dos Veadeiros National Park. The designation recognizes a protected sample of a major tropical savanna biome, whose plant and animal communities are distinct from those of the Amazon rainforest or the Pantanal.

Water is central to the park’s ecological story. ICMBio identifies rivers including the Taquari, Araguaia, Formoso and Jacuba among the waters preserved here. Their catchments link grassland, wetland and gallery-forest environments, and help explain why the reserve is important beyond its boundaries. Visitors may see termite mounds scattered across the grassland and seasonal flowers among the open vegetation. The visual impression is not a uniform plain but a mosaic of habitats shaped by soil, water and fire regimes.

Wildlife and the night-time glow

Emas protects Cerrado wildlife that is increasingly difficult to encounter in heavily converted agricultural landscapes. ICMBio lists species such as the giant anteater, maned wolf, giant armadillo, pampas deer and the greater rhea, the large flightless bird that gives the park its name in Portuguese. The unit’s records also include threatened species such as the jaguar and giant anteater. Wildlife sightings are never guaranteed; patience, quiet observation and respect for distance are essential, and visitors should not feed or approach animals.

The park is especially known for a seasonal natural spectacle: bioluminescent termite mounds. Larvae of luminous beetles live in openings in the mounds and emit a green light that attracts small prey. The Goiás state tourism service identifies October and November as the period when visitors may see the phenomenon, around the beginning of the rainy season. The display depends on local weather and biological conditions, so it cannot be promised on a particular night. It is a wild process, not a scheduled light show, and visitors should never disturb mounds or larvae to improve a photograph.

The glow draws attention to an ecological relationship that is easy to miss in daylight. The mounds are built by termites, but they can also shelter other organisms, including the luminous larvae. At night, scattered points of green light make the grassland appear unexpectedly alive. Guides and park staff can explain where observation is allowed and whether conditions are suitable. Because the site is a protected national park, access to special night-time activities is controlled; do not assume that entering after dark is permitted without arrangements.

Planning a visit and reaching the gates

ICMBio’s visitor information describes regular operation every day from 8 a.m. to 5 p.m., with the Bandeira and Jacuba entrance gates closing for lunch from noon to 1 p.m. It lists general admission as free and says advance booking is not required for ordinary entry. Special activities, access to particular areas, camping, safari-car outings, river recreation and some other experiences may require an accredited environmental guide or prior arrangements. These conditions are activity-specific; confirm with the park before travelling rather than treating the free general entrance as permission for every route.

There are two official land entrances: the Bandeira gate, reached from Chapadão do Céu or Costa Rica, and the Jacuba gate, reached from Mineiros. Distances and road surfaces differ. ICMBio’s visitor page describes an unpaved approach of about 30 kilometres from Chapadão do Céu to Bandeira, while the route from Mineiros to Jacuba includes a longer paved section. Road conditions can change with rain and maintenance, so verify the route before departure and allow extra time. Do not assume that the two gates connect conveniently for a short loop inside the park.

Self-guided trails are among the options identified by ICMBio, alongside activities operated with third parties such as cycling, boat outings, river float experiences and safari vehicles with a guide. The park’s map and risk-awareness rules are essential planning tools. Some activities require an authorized guide and have their own reservations or fees even though ordinary park entry is free. The federal online visitor service also includes Emas among protected areas with ecotourism activities for which advance arrangements may be needed. Ask the park which rule applies to the exact activity you want.

Travel responsibly in a remote landscape

Emas is not a drive-through zoo. Visitors should follow marked routes, obey gate instructions and stay within areas open to public use. Leave plants, animals and termite mounds undisturbed, carry out rubbish and avoid actions that could start a fire. The park protects habitats that are vulnerable to land conversion and changing fire patterns; responsible travel means recognizing that access is conditional on conservation, not an entitlement to roam everywhere.

Plan for distance, heat and limited services. Check current opening notices, activity requirements, road conditions and the forecast with ICMBio before setting out. Carry water and sun protection, and use local guides where required. The park’s visitor contact listed by ICMBio is +55 (64) 99972-8176; its official page also publishes an email for enquiries. Contact details and operating arrangements can change, so confirm them shortly before departure, especially for night activities or a multi-day itinerary.

Emas rewards travellers who come for more than a checklist of animals. Its value lies in the texture of the Cerrado: open fields, wetlands, tree-lined streams, wildlife and a seasonal glow that cannot be guaranteed on demand. Visit during the right period if bioluminescence is your goal, but treat it as a possibility rather than a promise. With current information and careful behaviour, a trip becomes an introduction to a rare savanna ecosystem and to the conservation work that keeps its landscapes functioning.
