How to get to Alter do Chão — and to the Arapiuns beyond it

Nobody arrives at the Rio Arapiuns by accident. The trip has four stages and each one is straightforward on its own; the thing worth understanding in advance is how they fit together, because getting one wrong costs a day.

Stage 1 — Fly to Santarém (STM)

Santarém sits where the Tapajós meets the Amazon, and its airport code is STM — Maestro Wilson Fonseca. It is the only sensible way in.

Direct flights run from Manaus (about 1h10–1h45), Belém (about 1h25, with frequent daily service) and Brasília (about 2h35, LATAM).

From São Paulo (GRU) there is no direct service. You connect, most often through Brasília. The best routings come in around 4h15 total; the routine ones stretch well past that, and a badly chosen itinerary can put you at ten hours. Return fares have been running roughly R$ 1,200–2,000, with the cheapest windows well before departure — booking around six weeks out has historically been the sweet spot.

Coming from abroad, the usual shape is an international flight into São Paulo, Brasília or Belém, an overnight there, then the morning flight to Santarém. Trying to connect straight through from an overnight transatlantic arrival is possible and reliably miserable.

One practical note: aim to land in Santarém before mid-afternoon. The last stage of this trip is on water, and river travel after dark is not something anyone here does casually.

Stage 2 — Santarém to Alter do Chão

About 33 km, roughly 40 minutes by road. Taxis and transfers wait at the airport; if you are being met, this is the leg your host arranges.

Alter do Chão is a village on a freshwater lagoon, with the sandbank called Ilha do Amor sitting in the middle of it. British press called it the Caribbean of the Amazon at some point and the name stuck. It is genuinely beautiful and, in the dry months, genuinely busy.

If your destination is Alter do Chão itself, you have arrived. If it is the Arapiuns, you are at the port.

Stage 3 — The boat up the Arapiuns

From Alter do Chão it is about 1h30 by speedboat, upriver, to Villa Arapiuns. You leave the Tapajós, turn into the Arapiuns, and the water changes character as you go: clearer, quieter, with white sandbanks appearing on both sides.

Two things people misjudge here.

The first is that this leg is not a transfer, it is the trip. It is the ninety minutes in which the phone stops mattering, and most guests describe it afterwards as the moment the holiday actually began.

The second is the landing. There is no deep-water pier. Depending on the river level you may step off into shin-deep water and walk the last stretch to the sand. Bring footwear that can get wet and pack anything precious somewhere dry. This is normal, it is not a sign that something has gone wrong, and it is the reason the beach in front of the lodge is a beach and not a concrete dock.

Community boats also run the river on their own timetable and are a fraction of the cost. They are a real option if you have time and flexibility, and a bad one if you have a flight to catch.

Stage 4 — Getting back out

Work backwards from the flight. From the Arapiuns to Alter do Chão is 1h30, plus 40 minutes to the airport, plus the check-in margin — so a midday departure from Santarém means an early start on the water, and an early-morning departure means the night before in Santarém or Alter do Chão. Say your flight time when you book and this gets planned around you.

What the trip actually costs in time

For a traveller leaving São Paulo, the honest arithmetic is a full day out and a full day back. From Europe or North America it is two days out, counting the overnight.

That is the argument for staying longer, and we would rather say it plainly than discover it with you: a two-night stay on the Arapiuns is two-thirds travel. Three or four nights is where the ratio turns, which is why our full-board rate starts at four.

What to bring

Sun protection is the real hazard, not wildlife: you are close to the Equator, on white sand, next to reflective water. Hat, long sleeves, high-factor sunscreen.

Repellent for forest walks at dusk — though the beach itself has no mosquitoes, which surprises people enough that we wrote about it separately.

Cash in reais. Some community activities are paid directly to the families who run them, and there is no card machine in the middle of a reserve.

A dry bag. See stage 3.

And less than you think. There is nowhere here that requires a change of clothes for dinner.
