Saül is a small village of a few hundred people sitting in the heart of the Guiana Amazonian Park, accessible only by light aircraft from Cayenne (about 45 minutes). It serves as the main trekking base for the territory's interior and is the best place in French Guiana to experience pristine primary rainforest with some infrastructure around it.
The village has a handful of gîtes (simple guesthouses offering half-board), a small shop, the wooden Église Saint-Antoine de Padoue at its centre, and a network of well-marked trails maintained by the national park. Short walks like the Saut Léodate waterfall trail and the steep Sentier du Belvédère — which gives a rare canopy view — are accessible in half a day. Longer routes, like the Grand Boucle du Mont La Fumée, lead deeper into the park. Most visitors hire a guide from the village; trails can be disorienting without local knowledge, and wildlife sightings improve dramatically with an expert eye.
Tapirs, giant anteaters, armadillos, and multiple monkey species live in the surrounding forest. Birdwatching is exceptional — toucans, macaws, harpy eagles, and hundreds of other species. Insects are spectacular and sometimes formidable.
Saül is at its best during the long dry season (July–November). Rain in the wet season doesn't stop visits but makes trails muddy and some routes impassable. Book accommodation and flights well ahead in high season.
