The Sentier du Belvédère is the steepest of the short trails out of Saül and the most rewarding for a first view of where you are. The path climbs through tall primary forest to a granite outcrop high above the canopy — one of the very few places near the village where the trees give way enough to see the green dome of forest stretching to every horizon, unbroken to the Brazilian border.
It is a three- to four-hour round trip from the village, with around 200 metres of climb, and tougher than the modest distance suggests because of the humidity. Bring more water than you think you need. Early morning is the best time — the light is better and the chance of seeing toucans and macaws crossing the gap above the canopy is highest in the first hour after dawn.
