Reunion 4 Day Itinerary (No Tourist Traps)

Four days brings in Cirque de Salazie and its village Hell-Bourg, the second of Reunion’s three cirques, alongside the coast, Cilaos and the volcano from the shorter plans. Roadless Cirque de Mafate and the Piton des Neiges summit still do not fit; that is what the 6 day and 7 day itineraries are for. If 4 days already feels tight, the 3 day version drops Salazie and keeps the volcano.

Book these before you go:

Day 1: Saint-Denis and the West Coast Lagoon

Land at Roland Garros (RUN) in Sainte-Marie, ten minutes from Saint-Denis, and collect your rental car at the terminal rather than waiting for a city branch. Europcar, Hertz, Sixt and the local Jumbo Car all run counters at arrivals, and a small automatic runs roughly EUR 20-25 a day in low season, more than double that in October. Reunion is French and EU territory that drives on the right, and it is not part of Mauritius, a separate country about 175km away that people constantly confuse it with. Give Saint-Denis an hour: Le Barachois waterfront still points its old cannons at the sea, and the Creole mansions along Rue de Paris are free to admire from outside. Then drive 35 to 40 minutes to Saint-Gilles-les-Bains for the afternoon. The protected lagoon at L’Ermitage is the one stretch of this coast where swimming is actually sanctioned; open-water swimming and surfing have been banned along most of the west coast since 2013 after a serious run of shark attacks, and the ban still holds in 2026, so treat every other beach here as a view, not a pool. Overnight in Saint-Gilles.

Day 2: Cirque de Cilaos

Cilaos is the cirque worth picking if you only get to choose one. The drive up from the coast takes 1h15 to 2 hours on a single paved road that racks up more than 400 numbered hairpin bends before it reaches town, so take them slowly and do not schedule anything else that morning. Early risers can detour up to the Maido viewpoint, about an hour up from Saint-Paul and best before 8am before the cloud rolls in, for the classic look down into Cirque de Mafate. Mafate has no road whatsoever, and the viewpoint or a helicopter flight are the only ways to see it without a multi-day hike. Cilaos itself is a genuine 19th-century thermal spa town and Reunion’s only wine-producing area (Pinot Noir, Malbec, Chenin), plus the source of the small pale lentils sold under its own name island-wide. Eat them with rice and a cari rather than a menu built for tour buses, soak at the Thermes if the afternoon allows, and check conditions with Meteo France La Reunion before you drive back down, since the hairpin road closes occasionally after heavy rain.

Day 3: Piton de la Fournaise

Piton de la Fournaise is one of the most active volcanoes on Earth, and it erupted three times between 13 February and 12 April 2026 before the alert level dropped back to baseline vigilance in May. Check fournaise.info or the prefecture before you drive up: caldera access opens and closes with the alert level, and no itinerary, including this one, can promise a crater walk months ahead of your trip. The drive from Cilaos to the Pas de Bellecombe car park, via Bourg-Murat and Plaine-des-Cafres, runs a genuine 2 to 2.5 hours on one dead-end road. National park entry is free; the marked trail across the Enclos Fouque lava plain runs about 4 hours to the crater rim one-way, so budget the whole day for it. The Cite du Volcan museum near Bourg-Murat (EUR 9 adult, EUR 6 child) is the fallback if the trail is closed. Overnight near Plaine-des-Cafres or Saint-Pierre.

Day 4: Cirque de Salazie and Hell-Bourg

Salazie is the lushest and wettest of the three cirques, and its single road ends at Hell-Bourg, officially ranked among France’s most beautiful villages for its Creole houses and carved wooden lambrequins. Getting here from the volcano side is a multi-hour transfer; nothing on this island connects two interior points without dropping back to the coastal ring road first, so budget most of the day for driving and treat the village itself as the payoff, not a detour to rush through. Just outside town, the Voile de la Mariee waterfall drops in several parallel strands down a cliff face and is visible right from the road, no hike required. Overnight in Hell-Bourg for the cooler mountain air, then return toward Roland Garros for departure.

Which cirque should you pick if you only have time for one?

Cilaos, without much debate. It packs a thermal spa town, Reunion’s only wine, its own lentils and the Piton des Neiges trailhead into one reachable base, and rewards even a single rushed day. Salazie and Hell-Bourg are more purely scenic; a village and a roadside waterfall in half a day, with less to actually do once you have looked at both. Pick Salazie only if you have a 4th day to spare, not instead of Cilaos.

Is Reunion Island part of Mauritius?

No. Reunion is a French overseas department and region, fully part of France and the Eurozone though outside Schengen and the EU VAT area. Mauritius is a separate, independent nation about 175km to the northeast; the two get confused because both are former French Mascarene sugar islands, but Mauritius was ceded to Britain in 1810 and Reunion stayed French. Never describe a Reunion sight as being in Mauritius.

Day Focus Drive/hike time
1 Saint-Denis + Saint-Gilles lagoon ~35-40 min drive
2 Cirque de Cilaos (spa, wine, lentils) ~1h15-2h drive, 400+ hairpins
3 Piton de la Fournaise (status permitting) ~2-2.5h drive, ~4h hike to the rim
4 Cirque de Salazie + Hell-Bourg multi-hour transfer, no shortcut

Hell-Bourg’s better tables fill up by 1pm once the day-tour vans arrive from the coast; book a Creole lunch ahead or eat late. The Parc National de La Reunion covers the whole cirques-and-remparts massif, which is also a UNESCO World Heritage site worth reading up on before you go.
