Anavilhanas

Anavilhanas is not a city but one of the great river-island wildernesses of the Amazon: the Anavilhanas National Park (Parque Nacional de Anavilhanas), a labyrinth of more than 400 forested islands, lakes, and igarapé channels strung along the Rio Negro between Manaus and the small town of Novo Airão. It is the second-largest freshwater (fluvial) archipelago in the world, surpassed only by the Mariuá archipelago further upriver near Barcelos, also on the Rio Negro. The islands are not permanent: they are built and reshaped by the seasonal rise and fall of the blackwater river, so the channels you paddle one month may be dry sandbanks the next. First protected as an Ecological Station in 1981 and upgraded to full National Park status in 2008, Anavilhanas sits within the cluster of conservation units of the lower Rio Negro.

The draw is the biodiversity and the eerie, mirror-black water. Because the Rio Negro is acidic blackwater, mosquitoes are far fewer than on the white-water Amazon proper, which makes this one of the more comfortable places in the basin for jungle travel. The park shelters jaguar, harpy eagle, giant river otter, pirarucu, spider monkey, and all of the Amazon's caiman species, and the waters off Novo Airão are famous for wild botos (pink river dolphins). Visitation is regulated and conservation-focused — independent wandering is limited, and most travel is by boat with a licensed guide or lodge.

Climate is hot and humid year-round (highs around 31–33 °C), and the experience is governed by water level rather than temperature. The high-water season (roughly May–July) floods the igapó forest and lets canoes glide between the treetops — the classic flooded-forest experience. The low-water season (roughly September–November) exposes white river beaches and concentrates wildlife, and is the better window for fishing and beach camping. The transitional months still work; there is no truly "bad" season, only different ones. Layout: there is no town inside the park — Novo Airão on the west bank is the principal gateway and where most lodges, the park's visitor structure, and the dolphin platform are based; Manaus is the regional hub you arrive through.

By Plane

The gateway is Manaus, served by Eduardo Gomes International Airport (MAO), about 14 km north of central Manaus and the only major airport in the region, with direct flights from São Paulo, Brasília, Brasília, and other Brazilian hubs. From the airport, a taxi or ride-hailing car into central Manaus is the normal first step; from there you continue overland or by river to Novo Airão and the park (see below). There is no airport at Novo Airão itself.

By Car / Road

From Manaus, the usual route to Novo Airão is by road via the bridge over the Rio Negro and the AM-070 highway, roughly 180 km / around 3–3.5 hours depending on conditions. Intercity vans and buses run the Manaus–Novo Airão route. Many travellers instead arrive as part of a lodge transfer or boat tour package, which combines road and river transport from Manaus. River travel along the Rio Negro is itself a core part of reaching and exploring the park.

Inside the park you move by boat — there are no roads among the islands. Lodges and licensed operators run motorized boats for transfers and longer trips and paddle canoes for quiet wildlife channels and the flooded forest. Independent boating is restricted by park rules, so in practice you travel with a guide or as part of a lodge program. In Novo Airão the town itself is small and walkable, and the waterfront (including the pink-dolphin floating platform) is easy to reach on foot. There is no metro, tram, or formal city bus network of note. Distances on the river are long and GPS/phone signal is patchy once you leave town — go with operators who know the channels, and confirm life jackets and return times before setting out.

The archipelago and flooded forest The headline sight is the maze of islands itself — hundreds of channels, igapó (flooded forest), and blackwater lakes. Best experienced from a canoe at high water, when you paddle between submerged crowns of trees. Access by boat with a guide; no ticket booth, but park visitation rules apply.

Wild pink river dolphins (botos), Novo Airão A floating platform on the Novo Airão waterfront is one of the most reliable places in the Amazon to see wild pink and grey river dolphins up close. Located on the town riverfront; hours and any entry contribution vary seasonally.

River beaches (low-water season) From roughly September to November the falling river exposes broad white-sand beaches along the islands — good for swimming, picnics, and overnight camping with operators. Visible/accessible only in the dry season.

Wildlife watching The park is habitat for harpy eagle, jaguar, giant otter, caiman (all Amazonian species occur here), pirarucu, and numerous monkeys and birds. Night boat trips for caiman-spotting and dawn outings for birds and primates are the standard ways to see them, always with a guide.

• Canoe the flooded forest — silent paddle trips through the igapó at high water are the signature Anavilhanas activity.
• Night caiman-spotting — guided boat trips after dark to find caiman by torchlight along the channels.
• Swim with / watch river dolphins at the Novo Airão platform.
• Sport and subsistence fishing — including the prized tucunaré (peacock bass); best in the low-water months. Confirm whether catch-and-release or permits apply with your operator inside the protected area.
• Jungle trekking — guided walks on the terra firme islands and forest, interpreting medicinal plants, tracks, and birdlife.
• Sunrise/sunset river outings — the blackwater mirrors the sky; classic photography moments.
• Beach camping (dry season) on exposed sandbanks with multi-day operators.

Food here is Amazonian river cuisine, built around freshwater fish and forest fruits. Lodges typically serve full board, and Novo Airão has simple local restaurants. Signature items to look for: tambaqui (often grilled ribs, costela de tambaqui) and pirarucu (one of the world's largest freshwater fish, served grilled or as pirarucu de casaca); tucumã (an oily orange palm fruit, classic in the x-caboquinho sandwich with tucumã, cheese, and banana); jambu (a tingling leaf used in regional dishes); and açaí, eaten in the Amazon as a savoury accompaniment, often with fish and farinha rather than as a sweet bowl.

• Lodge full-board dining (mid to upscale) — most park lodges include meals featuring fresh river fish, tropical fruit, and regional dishes; the most reliable option inside the park.
• Novo Airão waterfront restaurants (budget–mid) — simple eateries serving grilled fish, rice, beans, and farinha near the riverfront.
• Regional fruit and street snacks in Novo Airão — tucumã sandwiches, tapioca, and fresh-fruit juices.

The regional non-alcoholic stars are guaraná (both the bottled soft drink and the energising seed, native to Amazonas) and fresh Amazonian fruit juices — açaí, cupuaçu, graviola, and taperebá. Coffee and bottled water are widely available. On the alcohol side, expect cold beer (the universal Brazilian riverside drink) and cachaça-based caipirinhas, sometimes made with Amazonian fruits. Nightlife is minimal — this is a nature destination, and evenings revolve around the lodge, the river, and wildlife outings rather than bars.

Water safety: do not drink untreated river or tap water — stick to bottled or properly filtered/boiled water, which lodges provide. Carry enough for boat trips.

Budget

• Pousadas in Novo Airão — simple guesthouses in town offer basic rooms at the lowest rates and put you within reach of the dolphin platform and day tours into the park.

Mid-range

• Anavilhanas-area pousadas and smaller river lodges — mid-tier riverside lodging with guided excursions, typically sold as multi-night packages including meals and tours.

Upscale / eco-lodge

• Anavilhanas Jungle Lodge — a well-known eco-lodge on the Rio Negro opposite the park, with bungalows/chalets and all-inclusive multi-day programs (transfers, meals, guided excursions). Booked as packages rather than per-night room rates.
• Mirante do Gavião Amazon Lodge, Novo Airão — a design-forward boutique lodge on the riverfront, also run on all-inclusive package stays.

There is little conventional shopping in the park — come stocked from Manaus, where the Mercado Adolpho Lisboa and city shops sell Amazonian goods. In and around Novo Airão, look for local handicrafts, including basketry, wood carving, and items made by riverine (ribeirinho) and Indigenous artisans; Novo Airão has a long association with woodcraft. Typical regional buys across the area include guaraná products, Brazil nuts (castanha), and natural fibre crafts. Prices in small shops and craft stalls are generally fixed; gentle bargaining is more accepted at informal stalls than in established stores. Bring cash (Brazilian reais) — card acceptance and ATMs are limited once you leave Manaus.

• Novo Airão (gateway town, on the park's west edge) — base for dolphins, handicrafts, and park access.
• Manaus (~180 km / ~3 h by road, or by river) — the Amazon capital: opera house (Teatro Amazonas), markets, and the Meeting of the Waters where the dark Rio Negro meets the pale Rio Solimões.
• Presidente Figueiredo (north of Manaus, ~2–3 h by road) — waterfalls, caves, and forest trails, an easy nature add-on.
• Jaú National Park (further up the Rio Negro) — one of the largest forest national parks in South America, far wilder and harder to reach.
• Barcelos / Mariuá archipelago (upriver on the Rio Negro) — the world's largest fluvial archipelago and a famed sport-fishing region.
• Anavilhanas by liveaboard riverboat — multi-day Rio Negro cruises from Manaus that combine the park with remote igarapés.
