The boat eases away from Santarém at dawn and the Tapajós opens like a moving plain of light; sandbars appear and disappear as the currents play with the shoreline.

The boat eases away from Santarém at dawn and the Tapajós opens like a moving plain of light; sandbars appear and disappear as the currents play with the shoreline. On day one travelers step onto long, pale beaches at Alter do Chão, where warm, clear channels invite snorkeling and kayaks slip silently into shaded bayous.
This corner of the Amazon sits at the meeting of rivers and seasons—sediment-laden channels carved over millennia, beaches formed during low-water months, and riverbanks that supported indigenous and colonial trade routes long before tourism arrived. Small riverside communities along the Arapiuns River maintain artisanal traditions—seed and straw crafts, smoked fish recipes—and they welcome visitors with tangible local culture.
Expect varied terrain: wide sandy bars, narrow forested channels, shallow lagoons with excellent fish and visibility for snorkeling during the dry months, and dense riparian forest where howler monkeys call at dusk. Nights are simple and social—campfires on deserted beaches, barbeques, and hammocks aboard the boat Selvagem SOL.
Practical guidance: bring a dry bag, reef-safe sunscreen, sturdy water shoes for walking hot sand and rocky shallows, and a headlamp for evenings on the beach. Water levels matter—July–December exposes beaches and makes snorkeling clearer; the wet season raises channels and increases mosquitoes. The trip includes transfers from Santarém, three meals per day, fishing, kayaking, SUP, and comfortable cabin space on the boat. Plan for basic but safe accommodations, flexible schedules tied to river conditions, and leave no trace practices to protect the fragile river beaches.

Alter do Chão grew as a riverine settlement influenced by indigenous communities and later colonial river commerce; its beaches formed through seasonal sediment movement along the Tapajós.
