Saut Morin is a natural waterfall on a tributary of the Comté River system approximately 50 km south of Cayenne, reached by driving the D5 road toward Roura and then following a signed forest track to the car park. The waterfall is one of the most accessible natural swimming sites in the greater Cayenne area, making it very popular with local residents on weekends and during school holidays. The falls drop roughly 5–8 metres over dark granite outcrops into a clear, slightly tea-coloured pool — the colour is natural, derived from Amazonian tannins rather than pollution. The approach from the car park involves a 20–30 minute walk through secondary forest on a marked trail that crosses several small creek bridges and passes through productive bird habitat. At the falls themselves, a series of flat granite platforms provide natural sunbathing areas beside the pool, and the water is calm enough for swimming during the dry season. The pool depth below the main cascade reaches approximately 2–3 metres; bathers should avoid swimming directly beneath the falls during or immediately after heavy rainfall when flow increases dramatically and currents strengthen. Weekend afternoons see families and groups with picnics; weekday mornings the site is frequently empty. The surrounding forest still yields toucans, aracaris, and morpho butterflies along the approach trail.

Tips for visiting
- Visit on weekday mornings for solitude; weekends and school holidays bring large groups from Cayenne
- Avoid swimming immediately after heavy rain — water levels rise quickly and currents below the falls can become hazardous
- Bring a picnic as there are no food vendors on site; the granite platforms above the pool are excellent for lunch
- Waterproof sandals are useful for the rocky approach to the pool base; granite can be slippery when wet
- Combine with the Réserve Naturelle du Trésor, also near Roura, for a full-day nature excursion from Cayenne
- Insect repellent is useful on the forest trail, especially during morning hours
When to visit
September through November for the best swimming conditions after the long dry season. Weekday mornings for solitude. Avoid visits during and immediately after heavy rain due to rapid water level increases below the falls.
Accessibility
The trail from the car park to the falls is a forest footpath with roots and creek crossings — not accessible to wheelchairs or visitors with significant mobility limitations. The car park and the picnic area near the trailhead are accessible to visitors who cannot complete the full walk.
