One name, three very different visits
“The cirques” is a single phrase for three places that don’t behave the same way at all. Cilaos and Salazie are volcanic amphitheatres you can drive into: mountain roads wind down from the coast to villages, guesthouses and trailheads inside the crater walls. Mafate is the same kind of landform, but it has no road whatsoever. The only ways in are on foot, along marked trails from the Maïdo or from the col des Boeufs, or by helicopter, which mostly ferries supplies and building materials to the ilets rather than tourists on a timetable.
That single fact changes everything about how to plan a visit. A day trip to Cilaos or Salazie fits neatly into a rental-car itinerary. A visit to Mafate is a hiking trip with gîtes booked in advance, not a detour you add on a whim. This page sorts out which cirque does what, how long each one realistically takes, and where the Maïdo viewpoint over Mafate fits in without you ever setting foot there.
None of the three cirques should be confused with the Piton de la Fournaise, the active volcano in the island’s southeast. The cirques sit around the older, extinct Piton des Neiges in the center of Réunion Island; the Fournaise is a separate massif with its own access road, its own closures during eruptions, and its own destination page.
Cilaos: the drive, the canyons, the summit trailhead
Cilaos is reached from Saint-Louis by the RN5, a road with roughly 400 bends climbing from the coast into the crater. Budget about an hour of driving without stops, and expect it to feel longer than the kilometer count suggests: it’s a slow, attentive drive, not a fast one. Doing it for the first time in daylight is worth the wait if your ferry or flight timing allows it.
Once inside, Cilaos is the cirque with the most going on in a single village. It’s the trailhead for the Piton des Neiges summit hike, Réunion Island’s highest point at 3,070 m: most people overnight at the Caverne Dufour gîte and finish the climb before dawn for the sunrise, so this isn’t a same-day add-on to a Cilaos visit unless you’ve booked the gîte weeks ahead. Cilaos is also the island’s canyoning capital, with routes at Fleurs Jaunes, Gobert and Bras Rouge that combine abseiling, natural water slides and pools carved into volcanic rock.
a half-day canyoning descent at Fleurs Jaunes, combining abseils with panoramic views over the cirque is a practical way to sample Cilaos beyond the viewpoints, and a guided canyoning route from Bras Rouge into Cilaos, mixing aquatic slides with the geology of the gorge works well for a group wanting something more playful than technical.
Beyond hiking and canyoning, Cilaos has its own identity: thermal springs used since the 19th century, lentil cultivation on terraced slopes, and a small local wine industry, unusual at this altitude in the tropics. A Cilaos day trip from Saint-Gilles covers the drive, a short walk and lunch, and is the realistic version of “seeing Cilaos” if you’re not staying overnight or hiking to the summit.
Salazie: greener, closer, and Hell-Bourg
Salazie is reached from Saint-André on the island’s east coast, and the drive in is shorter and less demanding than the road to Cilaos. It’s also the greenest of the three cirques: the east coast’s higher rainfall means Salazie’s slopes are covered in dense vegetation, with waterfalls visible from the road itself, including the Voile de la Mariée cascading down a cliff face near the entrance to the cirque.
The village of Hell-Bourg is the main draw inside Salazie, classified among the Plus Beaux Villages de France for its creole houses and quiet streets. It’s an easy walking village, in contrast to Cilaos, which feels more spread out and geared toward hikers passing through. From Bélouve, above Hell-Bourg, a trail leads to a viewpoint over the Trou de Fer, a dramatic gorge with cascading waterfalls that’s otherwise difficult to see up close.
A Salazie day trip from Saint-Gilles typically covers the drive, a walk through Hell-Bourg and a stop at one of the waterfalls, and suits travelers who want the cirque experience without a long hike or an overnight stay. Compared with Cilaos, expect less elevation gain, shorter walks, and a softer, wetter landscape.
Mafate: on foot, or not at all
Mafate is the cirque with no road. There’s no way to drive, taxi or bus into it: every visit starts with a trailhead and ends with walking. The main entry points are the Maïdo (via the col des Boeufs or Roche Plate) on the west side, and Dos d’Âne further north, with several other trailheads used depending on which ilet you’re heading for. Ilets — small hamlets such as La Nouvelle, Marla, Roche Plate, Grand Place and Aurère — have gîtes that need to be booked in advance, since options are limited and supplies are constrained.
Helicopters do fly into Mafate, but mainly to deliver building materials, food and post to the ilets, and occasionally for scenic flights or emergencies — not as a routine way for visitors to arrive and leave. Anyone telling you they’ll drive you into Mafate has confused it with Cilaos or Salazie.
For a first Mafate visit, a guided day hike from the Maïdo rim is the lowest-commitment option: a guided walk around the Maïdo ridge, looking down into Mafate’s ilets and gorges without descending into the cirque gives you the view and the scale of the place without the logistics of a multi-day trek. For those ready to walk in, a guided group hike into Mafate via the Cayenne route, with an experienced local guide is a structured way to do a first crossing without route-finding alone. Multi-day treks covering several ilets, with gîte nights included, are best planned with the Mafate planning guide well before you land, since the popular gîtes fill up, especially in the dry season.
If your time or fitness doesn’t allow a Mafate hike, the west coast page covers the Maïdo viewpoint in detail: it’s the best way to see Mafate’s scale — ilets, ridgelines and the roadless gorges below — without walking in.
How the three cirques compare
| Cirque | How you get in | Time to allow | Main draw | Typical difficulty |
|---|---|---|---|---|
| Cilaos | Car, RN5 from Saint-Louis (~1h, ~400 bends) | 1 day by car; 2+ days with the Piton des Neiges | Canyoning, summit trailhead, thermal springs | Moderate driving; hikes vary widely |
| Salazie | Car, from Saint-André | Half-day to 1 day by car | Hell-Bourg, waterfalls, Trou de Fer viewpoint | Easy driving and walking |
| Mafate | On foot only (or helicopter for supplies) | 1 day hike (edge) to 3+ days (ilets) | Isolation, multi-day trekking, ilet life | Demanding; gîte bookings required |
Planning a realistic itinerary
Trying to “do all three cirques” in a single day from the coast is a common overreach. Cilaos and Salazie are on opposite sides of the island’s mountainous core, and the roads connecting them go back down to the coast and around rather than through — there’s no direct mountain road linking the two. A day trip covers one cirque properly; combining two in one day means a long day of driving with little time actually spent walking.
A more workable pattern: one day for Salazie (easier drive, shorter walks), a separate day for Cilaos (longer drive, more to do once there), and, if a Mafate trek fits your schedule and fitness, a dedicated 2 to 4 day block booked around gîte availability. The three cirques in four days itinerary lays out one way to sequence this without rushing the road to Cilaos or under-planning Mafate. If Mafate is the priority, the Mafate three-day trek itinerary focuses on that alone.
For flights and scenic overviews rather than driving or walking, a canyoning descent from Bras Rouge or a helicopter flight over Cilaos, Salazie and Mafate together (covered on the Saint-Pierre helicopter guide) gives a sense of all three cirques’ scale in under an hour — useful context before committing to which one to hike, or as a way to see Mafate’s roadless terrain from above if you won’t be walking in.
Season, weather and road conditions
Réunion Island’s seasons run opposite to Europe’s. May to October is the dry austral winter and the better window for the cirques: trails are firmer, river crossings in Mafate are lower and safer, and the Cilaos road is less prone to landslip closures after heavy rain. November to April is the humid austral summer and cyclone season; the east-facing approach to Salazie in particular can see heavy downpours, and trails — including sections used to reach Mafate — are sometimes closed by the ONF after storms. Check trail status before any hike, in any season, rather than assuming yesterday’s conditions still hold.
Temperatures inside the cirques are noticeably cooler than the coast, especially at altitude in Cilaos and on the Piton des Neiges route, where near-freezing mornings are normal in the dry season. Salazie, lower and wetter, stays milder but rarely dry for long. Pack a warm layer and rain protection for any of the three, regardless of how sunny the coast looks when you set out.
The full what to pack for Réunion Island guide goes through this in more detail for a whole trip, but the short version for the cirques is the same in any season: a fleece or light jacket for the morning cold, a rain shell for sudden showers, and shoes that have already been broken in before you’re two hours up a trail.
Where to stay: base in a cirque or day-trip from the coast
Most visitors stay on the coast at Saint-Gilles or elsewhere and day-trip into Cilaos or Salazie, which keeps a single base for the whole island and avoids packing and unpacking for one or two nights inland. It works well for Salazie, given the shorter drive, and reasonably well for Cilaos if you’re not also climbing the Piton des Neiges.
Staying inside Cilaos for a night changes the pace: hotels and gîtes in the village put you close to the thermal baths, the canyoning meeting points and an early start on the mountain trails, without the drive back down after dark. Salazie has gîtes around Hell-Bourg for the same reason, useful if you want a slow morning at the Trou de Fer viewpoint before the crowds. Mafate has only gîtes — there’s no hotel option — and beds in popular ilets like La Nouvelle need booking well ahead, especially in the dry season. The where to stay in Réunion Island guide compares coastal bases against staying inland in more detail, and things to do in Cilaos covers what fills a second day if you do stay over.
Reaching the cirques without your own rental car
A rental car is the default way most visitors reach Cilaos and Salazie, and the driving in Réunion Island guide covers what the RN5’s bends and the island’s mountain roads actually feel like behind the wheel. It isn’t the only option: the Car Jaune bus network, detailed in the Réunion Island by bus guide, runs services from Saint-André to Salazie and from Saint-Louis to Cilaos, though at a fraction of the frequency of a self-drive schedule, so a same-day round trip needs checking against the timetable rather than assuming a bus back whenever you’re ready.
Mafate removes the question entirely, since every visit starts on foot regardless of how you reached the trailhead — the getting around Réunion Island guide and the Réunion Island without a car itinerary both work through how far you can get across the island using buses and organized transfers alone, cirques included.
FAQ about visiting Cilaos, Salazie and Mafate
Can you drive to Mafate?
No. Mafate has no road connecting it to the rest of Réunion Island. You reach it on foot from trailheads including the Maïdo, the col des Boeufs and Dos d’Âne, or arrive by helicopter, which mainly serves the ilets with supplies rather than passengers on a regular schedule.
Which cirque should I visit if I only have one day?
Salazie is the easiest first taste: the drive from Saint-André is shorter and less winding than the road to Cilaos, and Hell-Bourg and the Voile de la Mariée waterfall are both close to the road. Cilaos takes longer to reach but rewards the drive with canyoning and access to the Piton des Neiges.
How long does the road to Cilaos take?
Around 1 hour from Saint-Louis without stops, covering roughly 400 bends on the RN5. It’s a slow, engaging drive rather than a long one in kilometers, and it’s worth doing in daylight the first time.
Is Cilaos or Salazie better for hiking?
Cilaos is the base for the Piton des Neiges summit hike and for canyoning routes such as Fleurs Jaunes and Bras Rouge. Salazie has gentler valley walks and the viewpoint toward the Trou de Fer from Bélouve, with less overall elevation gain.
How many days do you need in Mafate?
Most visitors spend 1 to 3 nights in ilets such as La Nouvelle, Marla or Grand Place, booking gîtes in advance. A single long day hike in and out from the Maïdo or the col des Boeufs is possible for fit walkers but only samples the edge of the cirque.
Is this the same as the volcano?
No. The three cirques (Cilaos, Salazie, Mafate) sit around the extinct Piton des Neiges in the center of the island. The active Piton de la Fournaise is a separate volcanic massif in the southeast, covered on its own destination page.
Do you need a guide to visit the cirques?
Not for Cilaos or Salazie by car, where you can drive yourself and walk marked trails independently. Canyoning routes and most Mafate treks are done with a qualified guide or outfitter, partly for safety and partly because gîte bookings and route-finding in Mafate reward local knowledge.
Can you visit the cirques without a rental car?
Salazie and Cilaos are both reachable by the island’s Car Jaune bus network from Saint-André and Saint-Louis respectively, though schedules are far less frequent than a self-drive itinerary and a same-day return from the coast needs planning around bus times. Mafate is walked regardless of how you arrive at the trailhead, so it’s the one cirque where not having a car changes the logistics the least.
What should you pack for a day in the cirques?
Layers rather than a single warm jacket: mornings in Cilaos and on any Piton des Neiges approach can be near freezing in the dry season, while the drive up from the coast starts in tropical heat. Add rain protection year-round, sturdy shoes for anything beyond a paved viewpoint, and cash for gîtes and small épiceries in Mafate, where card payment isn’t reliable.
