Backpacking in Sentier Scout
👌 Worth visitinghike ranked #3
By Johan Kruseman 🇳🇱 | Updated October 22, 2026

Sentier Scout is open to every hiker, and you don’t need any scouting link to walk it. It runs through the Cirque de Mafate in the west of Réunion, a roadless basin you enter only on foot. Expect a long climb up dry, sun-baked slopes where the air smells of hot rock and dust, then cooler ridges with wind in the tamarind and casuarina. The views are big and the footing is rough, with loose gravel on the steep sections and a hard, shadeless first stretch. Public transport reaches the lower valley, but the last stretch to the trailhead is yours to sort out, so check the last bus before you set off. Start early, carry more water than looks sensible (at least 2 liters), and book mountain huts ahead, because Mafate beds fill and there’s no road out. Unlike the busier Col des Bœufs approach, Sentier Scout is quieter and tougher.

✨ Why go?
Ranked #3 hike in RéunionWhy visitors keep coming back

Sentier Scout gives you a back door into Mafate that most visitors never use, and that is the main reason hikers seek it out. The climb is steep, around 1,200 meters of ascent, so you earn the cirque rather than reach it by a short, popular path. Because you arrive from the Rivière des Galets side, you see the landscape change from dry lowland scrub to cooler, greener ridges as you gain height, and you share the path with far fewer people than on the better-known entries. It also fits neatly into a longer route. Once you’re in the cirque, you can link on to Aurère and the Îlet à Malheur area, overnight in a mountain hut, and walk out by another trail the next day. Distances are flexible, so you can stop early at a village or push on. Everything beyond the trailhead is on foot, which gives … read more 👉

💡 HighlightsThe experiences that define the visit

  1. Cirque de Mafate panorama: The reason most people come. Once the climb levels out, the cirque opens up below you, a bowl of knife-edged ridges, deep ravines and tiny settlements with no road in sight. Morning light is clearest, before cloud fills the basin.
  2. Rivière des Galets valley: The opening stretch follows the dry, stony valley, where heat bounces off the rock and the vegetation is sparse. Looking back down the valley as you climb shows how much height you’ve gained, and the sea shows in the distance.
  3. Îlet à Malheur: One of Mafate’s small hamlets, with scattered houses, vegetable plots and a quiet, unhurried feel. It’s a good place to rest, refill water and see how people live without roads, with all supplies carried in on foot or by helicopter.

  4. Aurère: A small settlement in the cirque that makes a natural stop or overnight. Gîtes serve hearty Creole meals, usually rice with a slow-cooked rougail, which taste far better after a day of climbing.
Sentier Scout is best started at dawn with the Rivière des Galets valley, since the lower slopes are exposed and the first hours are the only comfortable ones.

Starting Point: The trail begins on the Rivière des Galets side, in the Sans-Souci area of La Possession. Urban buses serve the lower valley, but you may have to walk or take a taxi for the last stretch to the start.
Major Landmarks:
  • Rivière des Galets valley: The dry, rocky start with long views down toward the coast.
  • Mafate rim: The point where the cirque appears below you.
  • Îlet à Malheur and Aurère: Hamlets with gîtes, meals and water.
Terrain and Scenery: Stony path, loose gravel, rock steps and narrow ledges, with big views across ridges and ravines.
Vegetation: Dry scrub and grasses on the lower slopes, then tamarind, casuarina and greener forest on the higher ground.
Wildlife: Mostly birds, including the white-tailed tropicbird gliding along cliff faces. Mafate has no dangerous large animals, but wasps and mosquitoes can be a nuisance.
Practical Notes: Carry plenty of water for the lower section, wear a hat and sun protection, and start early. Reserve gîtes in advance and bring cash, as there are no shops on the route and the cirque has no road access.
⚠️ Hiking info can sometimes be outdated or inaccurate. Before you hit the trail, check the latest conditions with locals. If you do spot anything that's off, I'd love to hear from you, so I can update it for fellow travelers.

🛡️ SafetySafety Tips and Common Scams in Sentier Scout

Sentier Scout is a steep, well-trodden mountain path, and most problems come from heat, sun and underestimating the climbing. Much of the route is exposed, so start early, carry at least 2 to 3 liters of water, and wear a hat and sunscreen. Footing is loose on dry gravel sections and slick after rain, so trail shoes with real grip and trekking poles help on the descents. Afternoon cloud and showers roll in fast, especially in summer. Skip the route when heavy rain is forecast, since ravines flood quickly and cell signal is patchy in the cirque. Paths are marked, but fog can hide junctions, so download an offline map. No dangerous wildlife lives on the island. Take your trash out, stay on the path and leave plants alone. Book gîtes ahead, because there are no shops along the trail, and bring … read more 👉

FAQFrequently asked questions about Sentier Scout

Sentier Scout usually takes 5 to 7 hours one way at a steady pace, depending on where you start and finish. Many hikers split it into two days with a night in a Mafate gîte, where half board costs roughly €45 to 65. Stops for views and lunch add an hour or so, so leave early to finish in daylight.
Sentier Scout is moderate to demanding, mainly because of steep climbs and descents of roughly 800 to 1,000 meters of elevation change. The path is clearly marked and there are no technical sections, but loose gravel and sun exposure tire legs fast. Fit first-timers can manage it with an early start, trekking poles and plenty of water.
Sentier Scout needs neither a permit nor a guide, and walking it is free. The trail is marked and well used, so most independent hikers go without help. If you plan to sleep in Mafate, reserve a gîte in advance, as beds fill quickly in July, August and around Christmas. A local guide costs roughly €150 to 250 a day for a group, in case you want company or cultural context.
⚠️ Things can change over time, so always validate details locally before you go.

We 💚 feedbackIs it worth it?

Sentier Scout works best as a two-day trip: climb on day one, sleep in Mafate, and walk out the next morning when your legs have recovered. A day trip would waste the best part, which is the cirque at dawn. I would bring cash for the gîte and a light rain layer, because the cloud can drop in by afternoon.
