L’entonnoir Waterfall – A Hidden Jewel of Réunion Island
Discover the roar, the mist, and the magic of one of Réunion’s most dramatic waterfalls.
Introduction
If you’ve ever dreamed of standing beneath a curtain of water that tumbles more than half a kilometre down a sheer cliff, L’entonnoir is the place where that dream becomes reality. Nestled in the rugged interior of Réunion Island, just a short drive from the bustling capital of Saint‑Denis, this 600‑metre waterfall is a powerhouse of nature that few tourists see, yet it offers an unforgettable experience for the adventurous traveler. In this guide we’ll take you through everything you need to know to plan a perfect visit to L’entonnoir – from how to get there, to the best time of year to witness its thunderous plunge, and the hidden gems waiting nearby.
About L’entonnoir
What makes L’entonnoir special?
L’entonnoir (French for “the funnel”) lives up to its name: the water from the highland streams converges into a single, steep channel that funnels into a spectacular vertical drop of 600 m. While the exact altitude of the waterfall’s base is not recorded, the sheer height alone places L’entonnoir among the tallest waterfalls in the Indian Ocean region.
The waterfall is part of the Rivière des Galets watershed, which feeds several springs and small dams in the surrounding area. Its remote location means the surrounding forest has remained largely untouched, offering pristine scenery of volcanic basalt cliffs, lush ferns, and endemic birdlife.
A brief history
L’entonnoir has long been a landmark for the island’s early settlers and the indigenous Malagasy‑Creole communities that farmed the highlands. Historically, the powerful flow was harnessed for small‑scale irrigation, and the nearby Captage Bras de Sainte‑Suzanne weir (just 3.1 km away) still regulates water for local agriculture. In recent decades, the waterfall has attracted hikers, photographers, and eco‑tourists seeking a raw, uncommercialised natural spectacle.
Why it matters
Beyond its sheer visual impact, L’entonnoir plays an ecological role. The mist zone at the base creates a micro‑habitat for rare orchids and mosses, while the surrounding forest serves as a corridor for endemic reptiles such as the Réunion skink. For travelers, the waterfall offers a rare chance to witness the power of volcanic island hydrology in a setting that feels untouched by mass tourism.
How to Get There
From Saint‑Denis (the capital)
-
Rent a car or hire a local driver – The most flexible way to reach L’entonnoir is by road. From Saint‑Denis, take the N1 highway north toward Le Port, then follow signs for Cilaos (the mountain town that serves as the gateway to the highlands).
-
Turn onto the D43 – After passing the town of Sainte‑Suzanne, look for the D43 road heading east. This winding mountain road follows the Rivière des Galets valley and offers spectacular views of the island’s volcanic terrain.
-
Park at the trailhead – About 12 km from the D43 junction, you’ll find a modest parking area marked “Sentier L’entonnoir”. The parking lot is free but fills quickly on weekends, so aim to arrive early (7 am–9 am).
-
Hike to the viewpoint – The official trail to the waterfall’s viewing platform is 2.5 km round‑trip and moderately steep. Well‑marked signs guide you through a forest of Bambou de la Réunion (Reunion bamboo) and past a small spring (1.9 km away) that feeds the river. The hike takes roughly 45 minutes each way.
Public transport (if you prefer not to drive)
-
Bus: Take the Régie des transports de la Réunion (R.T.R.) line 1 from Saint‑Denis to Sainte‑Suzanne. From there, catch a local “taxi‑brousse” (shared minibus) heading toward Cilaos and ask the driver to drop you off at the D43 turn‑off.
-
Guided tours: Several local operators in Saint‑Denis and Cilaos offer half‑day waterfall tours that include transport, a guide, and a light snack. Booking in advance is recommended, especially during the high season (July–August).

Best Time to Visit
| Season | Weather | Water Flow | Visitor Experience |
|---|---|---|---|
| May – October (Dry season) | Cool, sunny days; low humidity | Moderate to high flow (rainfall from higher elevations) | Ideal for clear views, comfortable hiking, and vibrant photography. |
| November – April (Wet season) | Warm, frequent showers; higher humidity | Very high flow, sometimes dangerous | The waterfall is at its most powerful, but trails can be slippery and some sections may be closed. |
Recommendation: Aim for the dry season (May‑October), especially June to September, when the weather is stable and the trail is safest. Early morning visits give you the best light for photos and fewer crowds.
What to Expect
The visual spectacle
From the viewing platform, you’ll see water plummeting 600 m down a sheer basalt wall, creating a constant roar that can be felt in your chest. On sunny days, the mist forms a delicate rainbow that arches across the gorge—an Instagram‑worthy moment that many travelers chase.
Sensory experience
- Sound: The thunderous cascade drowns out most other noises, providing a natural soundtrack that’s both exhilarating and meditative.
- Smell: The air is saturated with fresh, mineral‑rich mist, mixed with the subtle scent of eucalyptus and wild orchids that thrive in the humid micro‑climate.
- Touch: If you venture close to the base (allowed only on guided tours), you’ll feel a fine, cool spray on your skin—perfect for a quick refresh after the hike.
Wildlife
Keep an eye out for the RĂ©union harrier soaring above the gorge, and listen for the distinctive calls of the Mauritian kestrel (a resident bird of prey). The forest floor is dotted with endemic ferns and occasional gecko sightings.
Nearby Attractions
While L’entonnoir is the star of the day, the surrounding highlands offer several complementary spots that enrich your itinerary:
- Spring (1.9 km away) – A clear mountain spring that feeds the river; a pleasant spot for a short rest and a photo of the crystal‑clear water.
- Dam (3.0 km away) – Small hydro‑dam used for local irrigation; offers a glimpse into Réunion’s sustainable water management.
- Captage Bras de Sainte‑Suzanne (Weir – 3.1 km) – An historic weir that regulates flow into downstream farms; the surrounding area is great for birdwatching.
- Second Dam (3.1 km away) – Another modest dam that creates a tranquil lake, perfect for a picnic.
- Cascade Maniquet (Waterfall – 4.2 km) – A more accessible, lower‑height waterfall that provides a family‑friendly swimming hole.
All these sites are reachable by the same D43 road, making it easy to combine them into a full‑day adventure.
Travel Tips
| Tip | Details |
|---|---|
| Footwear | Wear sturdy hiking boots with good ankle support. The trail can be slippery, especially after rain. |
| Clothing | Pack a lightweight rain jacket even in the dry season; mountain weather can change quickly. |
| Hydration | Bring at least 1.5 L of water per person. There are no water refill stations on the trail. |
| Sun protection | The sun is strong at altitude; use sunscreen, a hat, and UV‑blocking sunglasses. |
| Safety | Do not attempt to descend to the base of the waterfall unless you’re with a certified guide. The rocks are unstable and the flow can be unpredictable. |
| Photography | The best light is early morning or late afternoon. Use a polarizing filter to reduce glare on the water and enhance the rainbow effect. |
| Leave no trace | Pack out all trash, stay on marked paths, and avoid picking plants or disturbing wildlife. |
| Local etiquette | Respect the private farms that line the road; ask permission before crossing any farmland. |
| Currency | Réunion uses the Euro (€). Credit cards are accepted in Saint‑Denis and Cilaos, but carry cash for small purchases in rural areas. |
| Connectivity | Mobile signal can be spotty on the mountain; download offline maps (Google Maps or Maps.me) before you set off. |
