Lago Verde and the Enchanted Forest
Half an afternoon by boat through the creeks of Lago Verde, swimming at Pindobal beach and sunset at Ponta do Cururú, where pink river dolphins appear.

Alter do Chão, Pará, Brazil
Half-day trips to four-day expeditions across the Tapajós, Arapiuns and Amazon rivers. Guided by people who have lived here since 2008.
About us
Mãe Natureza has operated out of Alter do Chão since 2008. Our guides come from the communities we visit: Jamaraquá, Maguary, Urucureá, Maripá. The person opening the trail lives on it.
What you can do
All depart from Alter do Chão. Prices are per person and include transport, guide and protected-area fees.
Half an afternoon by boat through the creeks of Lago Verde, swimming at Pindobal beach and sunset at Ponta do Cururú, where pink river dolphins appear.
The Tapajós National Forest with an overnight stay in a family home in Jamaraquá. The hunting trail almost no tourist walks, night canoeing for caiman, and the ancient kapok trees.
Three days crossing all three rivers: Tapajós, Arapiuns and Amazon. The communities of Jamaraquá, Maripá and Urucureá, and the Jarí floodplain where the wildlife concentrates.
Four days sleeping in a hammock on board, across the Tapajós, Arapiuns and Amazon. Fish baked on a deserted beach, a six-hour trail, and the kapok tree it took twenty people to encircle.
Four days on the north bank of the Amazon, among rock paintings 10,000 to 12,000 years old, the Vale do Paraíso waterfall and the wind-carved rocks of the City of the Gods.
Fishing in protected areas with all gear included. Lago Verde, Muretá and Pindobal, or the more distant lakes of Maripá and Bacurí in the Reserve.
The region
The Tapajós runs clear and green, nothing like the brown of the Amazon. It rises and falls almost six metres a year, and that changes everything you can do here.
August to December
White sand beaches emerge. Ilha do Amor, which the Guardian named the best beach in Brazil, becomes a sandbar you can walk across by November. There are almost no mosquitoes this time of year.
February to August
The water rises and the beach disappears. In exchange, you paddle a canoe straight into the Enchanted Forest, a maze of submerged trees full of birds and monkeys. This is when the forest itself becomes navigable.
There is no bad season. There are two different trips.
How we work
Speedboats for up to 7, covered launches for 18, 18-metre boats with kitchen and bathroom, and a barge with 11 en-suite cabins for groups who want to take their time.
The person leading the trail was born on it. You learn about medicinal plants, canoe timber and forest vines from someone who uses them daily.
Lunch in a family home, handicrafts bought directly from the women's association in Urucureá, overnight stays in community lodges. The tour pays the people who live there.
The Tapajós National Forest and the Arapiuns Reserve are protected areas requiring fees and permits. All of it is already in the price.

Mãe Natureza is also a photography collective. Every image on this site was taken on our own trips.












It depends what you want. August to December brings white sand beaches and almost no mosquitoes. February to August the water rises and you can paddle through flooded forest. July is the most crowded month.
Fly into Santarém (STM), 45 minutes away by car. We include the transfer on multi-day programmes.
For beach and creek trips it helps but is not required. Life jackets are provided on every boat.
Far fewer than most people expect. The Tapajós is acidic and clear, which greatly limits breeding. In the dry season there are almost none.
On day trips, yes, and it is common. For overnight expeditions in the forest we talk through age and itinerary beforehand.
Insect repellent, sunscreen, a hat, swimwear, a dry change of clothes, closed shoes for trails, and a torch on overnight programmes. Hammock and mosquito net are ours.
