Mafate Hiking Guide: Réunion's Roadless Cirque
Plan your trip
Mafate is the only cirque in Réunion with no road access — the caldera walls on all sides are too vertical and unstable to build on. The villages inside (Ilet-à-Bourse, La Nouvelle, Marla, Ilet-à-Malheur, Grand Place, Roche-Plate, and several smaller hamlets) are accessible only on foot or by helicopter. Their inhabitants — several hundred people in total — receive supplies by helicopter, generate their own electricity, and maintain schools, churches, and small guesthouses (gîtes) that have been welcoming hikers since the cirque opened to tourism in the 1970s.
The result is one of the most extraordinary walking destinations in the Indian Ocean — a mountain cirque that functions as a genuinely inhabited alpine world, with trails connecting villages through spectacular canyon and ridge terrain, and a gîte system that provides beds, hot meals, and cold beer at the end of each day’s walking.
The Character of Mafate
The cirque walls rise 1,000–1,500m above the villages. From most of the village sites, looking up reveals a complete ring of basalt cliff. From the rim trails above, looking down reveals a patchwork of gardens and tin-roofed houses in the valley far below, connected by thin trails visible only when the cloud lifts.
The vegetation changes dramatically with altitude: below 1,500m, a mix of introduced fruit trees (mango, tamarind, guava), garden plots, and secondary bush. Between 1,500m and 2,000m, the native tamarind and Réunion tree heather transition zones. Above 2,000m, the exposed ridge terrain with endemic plants and the open views across the cirque.
Wildlife is less prominent than on the volcano side of the island, but the Réunion harrier (a raptor found only on this island) soars above the cirque on thermal currents, and several endemic bird species are present in the native forest sections.
Entry Routes
From Dos-d’Âne (Route des Colimaçons, north)
The most direct entry — a 3-hour walk from the Dos-d’Âne roadhead (north Réunion, accessible by bus from Saint-Denis) descending the steep Aurère ridge into the Mafate cirque floor. The descent is well-maintained but steep; ascending via this route is more demanding.
First village: Ilet-à-Bourse or La Nouvelle depending on your descent path.
From Cilaos (Brèche de Mafate, south)
The most scenic approach — a high-altitude traverse over the Brèche de Mafate (2,010m) from the Cilaos side, descending into the cirque from the south. This approach provides the most dramatic entry — the view from the pass into the cirque with La Nouvelle visible below is the classic Mafate arrival image.
Access from Cilaos: 3 hours from Cilaos to the pass, 2 additional hours down to La Nouvelle.
From Saint-Paul / La Rivière des Galets (west)
The main western entry along the Rivière des Galets river bed — a flat approach through the gorge, then climbing to the cirque villages. Used less frequently but useful for combining with a coastal section of the GR R1.
Helicopter (Hélilagon)
For those unable to hike in, or for emergency purposes — helicopter transfers from Saint-Paul and Saint-Denis to any Mafate village (~€60–100 per person one way). The flight is 10 minutes; the landing zones are football-pitch-sized clearings in the cirque floor.
The Main Villages
La Nouvelle (1,083m)
The largest and most central village in Mafate — a community of approximately 120 people, with the best selection of gîtes, a school, a church, and the main helipad. La Nouvelle is the natural base and the most connected village (several trails radiate from here in all directions).
Gîtes: 5–6 gîtes with demi-pension (dinner + breakfast). Book well in advance for weekends and holiday periods. The food quality at Mafate gîtes is consistently good — carri, rougail, lentils, home-grown vegetables.
Marla (1,641m)
The highest and most alpine of the main Mafate villages — at the southern edge of the cirque at significant altitude, with views south toward Piton des Neiges. Cooler than La Nouvelle; more often in cloud. Fewer gîtes; wilder character.
Ilet-à-Bourse (1,088m)
Northeast of La Nouvelle — a smaller, quieter village with a more traditional character. Good for those wanting to avoid La Nouvelle’s relative bustle.
Grand Place les Hauts (860m)
Southeast Mafate, accessible from the Dos-d’Âne entry or via trail from La Nouvelle. Lower, warmer, more lush vegetation.
Multi-Day Routes
3-Day Loop from Dos-d’Âne
Day 1: Dos-d’Âne → La Nouvelle (3 hours descent). Afternoon rest, explore village. Day 2: La Nouvelle → Marla (3 hours via high ridge trail, gain 558m). Marla overnight. Day 3: Marla → Cilaos via Brèche de Mafate (5 hours). Requires pre-arranged transport or accommodation in Cilaos.
4-Day Grand Cirque Traverse
Day 1: Dos-d’Âne → Ilet-à-Bourse Day 2: Ilet-à-Bourse → La Nouvelle → Roche-Plate (western Mafate, lower trail, longer day) Day 3: Roche-Plate → Grand Place → Ilet-à-Malheur (cirque traverse) Day 4: Ilet-à-Malheur → exit via Rivière des Galets to Saint-Paul
GR R1 (Grand Randonée Route 1)
The full island traverse that crosses Mafate as a section — the GR R1 enters Mafate from Cilaos, crosses the cirque, and exits via the Dos-d’Âne route. The complete GR R1 traverses the entire island over 10–12 days, passing through Cilaos and Salazie as well as Mafate. The Mafate section alone (3 days) is the most spectacular segment.
Gîte Reservations
Essential: Mafate has limited beds (total capacity across all villages is perhaps 200–300 people per night). Reserve by calling directly or through the Centrale de Réservation des Gîtes de Montagne (gites-de-montagne.re). Weekends between June and October (dry season, peak hiking) require booking 4–6 weeks ahead.
Price: Demi-pension (dinner, bed in shared or private room, breakfast): €45–65/person. Bring cash — no card payments in Mafate.
What to expect: A typical gîte has 2–4 person rooms (often shared dormitory for budget), a communal dining room, outdoor facilities. The food is good, generous, and specifically Réunionnais. The conversation at the dinner table often involves hikers from multiple countries comparing routes.
Practical Notes
What to bring: Water capacity for 4–5 hours between sources (several trails have no water; check with gîte owners the night before). Snacks for the day (gîtes don’t provide lunch, though some sell basic supplies). Good trail shoes (not hiking boots necessary for summer dry season; the trails are rocky but not technical). Headlamp.
Navigation: Trails are marked with orange paint on rocks throughout. The 1:25,000 IGN Réunion maps cover Mafate in detail. A GPS track (downloadable from alltrails.com or IGN) is useful as a backup.
Weather: Mafate receives heavy rainfall (the cirque captures cloud from both sides of the island). Morning departures maximize clear conditions before afternoon cloud. The dry season (May–October) has significantly more reliable morning weather.
