Bassin des Aigrettes is one of La Réunion’s most visually stunning yet off-limits natural sites — a tucked-away waterfall and basin in the highlands above Saint-Gilles that continues to attract the curious despite its official closure.

A short trail leads to this quiet ravine, where a graceful waterfall tumbles into a cool green pool, surrounded by flat basalt rocks perfect for sunbathing and quiet reflection. It feels like a secret spot from another time.

But here’s the truth: access is forbidden. The site is fenced off due to landslide risk and its function as a protected water source for the town of Saint-Gilles. Despite this, many people still sneak in to swim or picnic, drawn by photos and word-of-mouth. Entering is done at your own risk — and fines or injury are real possibilities.

Nearby, two other hidden basins — Bassin Cormoran and Bassin Malheur — also exist but are even harder to reach, steeper, and equally unofficial.

If you’re seeking the same kind of peaceful beauty in a legal and safe way, consider:

• Bassin des Hirondelles near Saint-Benoît,

• Bassin la Paix or Bassin la Mer in the east,

• Or one of the cascades in Cilaos or Salazie.

👉 Pro Tip: If you’re determined to visit, go early, wear sturdy shoes, and don’t attempt it after rain. But better yet — respect the closure and discover one of La Réunion’s many officially maintained treasures.
👉 Hidden Gem: From the outside of the fence, you can still hear the waterfall and catch glimpses through the trees — a taste of what lies beyond.
