Lagoa das Araras: Nobres' Sunset Macaw Spectacle

Lagoa das Araras sits 2 km from Bom Jardim village in Nobres, Mato Grosso, and every afternoon from about 4:30 PM, dozens of yellow-and-blue macaws return to nest in the dead buriti palms that ring the water. Entry costs R$35–50 via a mandatory digital voucher, and the show lasts roughly 90 minutes until sunset. Most visitors base themselves in Bom Jardim — not Nobres town, which is 65 km away — because the lagoon and the region's crystal-clear rivers are all clustered around the district.

The lagoon formed when natural flooding killed a stand of buriti palms, leaving hollow trunks that macaws have used as nesting cavities for generations. That accident of nature turned a small Cerrado lake into one of the most reliable birdwatching sites in central Brazil. You don't need a guide, binoculars help, and the ground is flat the whole way.

Getting There and Orientation

From Cuiabá to Bom Jardim

Drive 150 km from Cuiabá on the BR-163 to Rosário Oeste, then take a secondary road into Bom Jardim. The trip takes 2 to 2.5 hours in dry conditions. There is no airport in Nobres, so rent a car at Cuiabá's Marechal Rondon airport or book a transfer through a local agency. A handful of tours run day trips from Chapada dos Guimarães for around R$600 per person, but staying overnight in Bom Jardim gives you a calmer sunset.

The Final Approach

The lagoon entrance is off the main road with a simple gate and a wide gravel parking area. From the village center, it's a 2–3 km walk or bike ride on flat pavement. Many visitors arrive by bicycle in the late afternoon — a pleasant option since the road is shaded in stretches. The site has limited facilities: no restaurant, no guided interpretation, and only basic restrooms. Bring water.

The Sunset Ritual: What Actually Happens

Timing Your Arrival

Gates open around 4:00 PM, but plan to be in position by 4:30. The first macaws usually appear 30–40 minutes before sunset, flying in pairs and small groups. On a good evening, 40 to 80 birds gather. Cloudy or windy days reduce numbers, and there's no guarantee — this is wildlife, not a scheduled show. I've seen evenings with barely a dozen birds and others where the sky seemed full of them; local guides say the weeks around the end of the dry season (August–September) are most consistent.

Where to Stand

Two boardwalks offer elevated views over the lake and palms. The first one, closest to the entrance, gives the classic panorama and is the best spot for macaw viewing. A gravel path circles about 20% of the lake perimeter before turning into a dirt trail through the forest. Avoid the temptation to walk right up to the nesting palms — the birds are sensitive, and the boardwalk view is better anyway. Photographers should note that the sun sets behind the palms, so the strongest light on the birds comes in the first 20 minutes of arrival, not at the very end.

The Sound

The macaws are loud. Their calls — a harsh, rolling screech — echo across the water as they settle into the hollow trunks. You'll also see white egrets, parakeets, and occasional parrots. The full experience from arrival to darkness is about 1.5 hours. There is no guide on site, so bring your own curiosity and a pair of binoculars if you have them.

Practical Details: Tickets, Rules, and Best Season

Vouchers and Pricing

Visitation is organized through Nobres' digital voucher system. Entry fees range from R$30 to R$50 depending on the season and agency, and some hotels include the voucher in packages. Book through your pousada or an authorized agency at least a day ahead during high season (June–August). Fees are subject to change — check with the local tourism office or your accommodation for current rates. The 2026 rate appears to be R$35–50; older reviews citing R$10–15 are outdated.

Wildlife Rules

Drones are forbidden at the lagoon — several visitors have reported that drone use disturbs the birds and is not tolerated. Keep noise low, stay on the trails and boardwalks, and never approach the nesting trunks. There's no fencing around the water's edge, so supervise children. The site is managed as an ecological sanctuary, and the birds' routine is the main attraction; respect it.

When to Go

The dry season, May through September, brings the most reliable weather and the clearest river water for the region's other activities. June and July are the busiest months, with noticeably more visitors at the lagoon. If you want a quieter sunset, aim for late April–May or September–October. The rainy season (November–April) can still deliver good birdwatching, but afternoon thunderstorms sometimes cancel the show entirely. Temperatures hover around 25–32°C year-round; bring insect repellent for the walk from the parking area.

Frequently Asked Questions

How long should I plan for Lagoa das Araras?

Allow 1.5 hours on site: arrive by 4:30 PM, watch the macaws for about an hour, and stay through sunset. The drive from Bom Jardim takes under 10 minutes, so the whole outing from the village is about 2 hours.

Do I need a guide or a reservation?

No guide is required, and the site is self-guided. You must have a digital voucher, which you can buy through your pousada or an authorized agency; walk-up entry without a voucher is not guaranteed. Book a day ahead in June–August.

What is the best time of day to see the macaws?

Arrive between 4:30 and 5:00 PM. The birds begin returning roughly 40 minutes before sunset, and activity peaks in the final half-hour of daylight. Morning visits are not productive for macaw watching.

Is the lagoon accessible for strollers or wheelchairs?

The main viewing area and first boardwalk are flat and reached via gravel, suitable for sturdy strollers and wheelchairs with some assistance. The dirt trail around the lake's perimeter is not accessible. Parking is directly at the entrance gate.
