Three cirques in four days: Cilaos, Salazie and Mafate by road

What four days actually buys you

Réunion Island has three volcanic cirques — Cilaos, Salazie and Mafate — and each one deserves its own trip. Four days is not that trip. It is a road-based introduction: one night in Cilaos, one stop in Hell-Bourg, and a sunrise viewpoint over Mafate from the Maïdo. You will see three genuinely different landscapes, but you will not walk into any of them for more than an afternoon. If that honesty puts you off, two other itineraries on this site go further: Mafate in three days: a car-free trek from ilet to ilet is the real multi-day walk into Mafate’s ilets, and Seven days hiking Réunion: Mafate, Cilaos, Salazie and the volcano covers all three cirques on foot over seven days. This one is for a mid-range trip by rental car, for travellers who want a taste of each cirque without trekking.

The route only works with your own car — see Driving in Réunion Island: what the roads are actually like and Renting a car in Réunion Island before you book. Distances on the map are short; the mountain roads are not. Budget the time below rather than the kilometres.

Day 1: Saint-Gilles or Saint-Denis to Cilaos

Leave in the morning. From the west coast, the drive to Cilaos runs via Saint-Louis and then onto the RN5, the road with roughly 400 bends that climbs into the cirque. Count on about an hour of continuous, tight driving from Saint-Louis once you leave the coast, more if you stop at the viewpoints along the way (and you should — Roche Merveilleuse and the Fleurs Jaunes gorge are both worth five minutes out of the car). It is not a long trip in kilometres and it is a genuinely tiring one in concentration; passengers prone to motion sickness will feel it more than the driver.

Once in the village of Cilaos, check into your accommodation and spend the afternoon at an easier pace: the thermal baths (a low-key, slightly old-fashioned spa built around Cilaos’s mineral springs), the embroidery workshops in the village, or simply the terrace of a restaurant with a plate of Cilaos lentils. If you have booked an afternoon canyoning session instead, this is the day for it — see below.

Dinner in Cilaos usually means a table d’hôtes or a small créole restaurant serving lentils, pork and local wine; book ahead in high season, since the village is small and fills up.

Day 2: Cilaos — canyoning or thermal springs, then to Salazie

Morning in Cilaos is the best window for canyoning, before the afternoon heat and the chance of storm buildup over the peaks. The Fleurs Jaunes and Bras Rouge canyons near Cilaos are the classic introductions: a half-day of abseiling down waterfalls and sliding through carved rock pools, guided, with no prior experience required for the standard routes.

If canyoning is not for you, the thermal baths and a short walk to a viewpoint make an equally valid morning — this itinerary does not require the adrenaline stop, only the overnight in Cilaos to justify the drive up. For hikers who want more than a viewpoint, a short guided walk from Cilaos is an option; see Things to do in Cilaos: canyoning, thermal springs and the road with 400 bends for the range of half-day options.

By early afternoon, head back down the RN5 and around toward Salazie and Hell-Bourg. There is no direct mountain road between the two cirques; the connection runs back through the lowlands, so allow roughly two to two and a half hours door to door, more with a lunch stop. Arrive in Hell-Bourg in time to walk the village before dinner — light fades fast against the cirque walls.

Day 3: Hell-Bourg and the Salazie waterfalls

Salazie is the greenest and wettest of the three cirques, and it shows: waterfalls appear around almost every bend of the access road, the best-known being the Voile de la Mariée cascade tumbling down the cliff face just before you reach the village. Hell-Bourg itself is worth a slow morning — it is one of France’s officially listed Plus Beaux Villages, built around 19th-century créole houses with carved wooden balconies, a legacy of the thermal-spa era before a 1948 flood buried the original springs.

From Hell-Bourg, a short drive or a longer walk up toward Bélouve gives a distant view toward the Trou de Fer, one of the island’s deepest and most dramatic waterfall gorges, usually seen from a platform rather than up close. If you have time and energy for one real walk on this trip, this is a reasonable place to spend it — a few hours out and back rather than a full day.

By late afternoon, start the drive back toward the west coast, since tomorrow’s Maïdo start is early. The road from Salazie down to Saint-André and around to Saint-Paul or Saint-Gilles takes roughly two hours without traffic, longer around Saint-Denis at peak times. Sleep on the west coast to shorten tomorrow’s pre-dawn drive.

Day 4: sunrise at the Maïdo, looking into Mafate

The Maïdo viewpoint, at roughly 2,200 metres above Saint-Paul, is the only part of this itinerary that touches Mafate — and it touches it only by sight. There is no road into Mafate: the cirque is reached exclusively on foot, from trailheads including the Maïdo itself, the Col des Boeufs and the Rivière des Galets, with supplies for the scattered ilets flown in or carried in on foot. If you want to actually walk into Mafate, that is a separate multi-day trip; this itinerary only gets you to the edge.

Leave the coast well before sunrise — the drive up from Saint-Paul takes about 45 minutes to an hour on a narrow, switchbacked road, and the viewpoint is at its clearest in the first hour or two after dawn. Cloud typically builds up from around 10am, sometimes earlier, and can erase the view entirely within twenty minutes. Arriving late is the single most common way to miss the point of the Maïdo.

For travellers who do want to set foot in Mafate rather than look at it, guided day hikes from trailheads like the Maïdo or Cayenne exist, but they enter the cirque rim rather than complete a crossing — a genuine multi-day trek is the only way to see the ilets like La Nouvelle or Marla.

Once the cloud closes in, there is little reason to linger. Head back down to the coast for a late breakfast and, depending on your flight or ferry, an easy final afternoon around Saint-Gilles or Saint-Leu.

What this trip covers, and what it does not

Cirque	What you get in 4 days	What you skip

Salazie	Hell-Bourg village, waterfalls, a distant Trou de Fer view	The GR R1 traverse and Bélouve forest in depth
Mafate	A viewpoint from the Maïdo, no road, no footsteps inside	Any of the ilets — La Nouvelle, Marla, Roche Plate — reachable only on a multi-day walk

Practical notes for the drive

Rent a car with reasonable ground clearance and, if you can, one you are comfortable placing precisely on a narrow road — the RN5 to Cilaos and the Maïdo access road both have sections with no guardrail and oncoming traffic on blind bends. Fuel up before climbing to either Cilaos or the Maïdo; there is no station in Cilaos itself worth relying on for a top-up, and none at all near the Maïdo summit. Mobile coverage drops out in patches inside both cirques.

This itinerary works in either the austral winter (May to October), when skies are drier and the Maïdo view is more reliable, or the austral summer (November to April), when cloud and rain are more likely, especially at Salazie, and cyclone-season disruption is possible from around December to March — check the forecast and prefecture alerts before you commit to the RN5 climb, which can close after heavy rain. See Réunion Island cyclone season: a booking and safety guide if you are travelling in that window.

FAQ: three cirques in four days

Can you really see Cilaos, Salazie and Mafate in four days?

You can see the first two properly by road and on foot for a few hours each, and you can look into the third from the Maïdo viewpoint. You cannot walk into Mafate in this timeframe — that requires a dedicated multi-day trek, since no road reaches any of its ilets.

Do I need a 4x4 to drive to Cilaos or the Maïdo?

No. Both roads are paved and manageable in a standard rental car; what they demand is a driver comfortable with continuous hairpin bends and no shoulder in places, not four-wheel drive.

Is one night in Cilaos enough?

It is enough to get a real feel for the cirque, a canyoning session or the thermal baths, and a créole dinner. It is not enough for the Piton des Neiges summit hike, which needs an overnight at a mountain gîte and its own itinerary.

Why does the itinerary put Mafate at a viewpoint instead of inside the cirque?

Because Mafate has no road. Reaching any of its ilets means a walk of one to three days from a trailhead like the Maïdo, the Col des Boeufs or Dos d’Ane, with an overnight in a gîte. The Maïdo belvedere is the honest way to include Mafate in a four-day, mostly-driving trip.

What time should I leave for the Maïdo sunrise?

Early enough to be at the viewpoint by first light, since cloud regularly builds up from around 10am and can block the view within minutes. From the west coast, allow about 45 minutes to an hour for the drive up, plus a safety margin.

Can I do this trip without a rental car?

Not comfortably. Car Jaune buses connect coastal towns but do not serve Cilaos, Hell-Bourg or the Maïdo on a schedule that fits this itinerary; see Getting around Réunion Island by bus: the Car Jaune guide for what public transport can and cannot do here.

Is this itinerary suitable for someone who is not a strong hiker?

Yes — it is built around driving, short walks and one optional canyoning or hiking session, not sustained trekking. The demanding part is the mountain driving, not the walking.

What should I book in advance?

Cilaos accommodation in high season, any canyoning or hiking session, and — if you plan to walk further into Mafate afterward — the gîtes there, which fill up weeks ahead. See Hiking in Mafate: planning guide if you decide to extend the trip on foot.
