Reunion Off the Beaten Path: 4 Day Itinerary
Four days is the point where Reunion stops being a coastal trip and starts being a volcanic one: Saint-Denis, the lagoon, Cilaos, and then a drive to one of the most active volcanoes on Earth. Piton de la Fournaise erupted across three separate phases between February and April 2026 alone, so this plan treats caldera access as a day-of decision, not a guarantee. Shorter on time? The 3 day plan stops at Cilaos. Want Salazie too? Move up to the 5 day itinerary .
| Day | Focus | Drive time |
|---|---|---|
| 1 | Saint-Denis arrival, the Barachois waterfront | 10-15 min from Roland Garros airport |
| 2 | Saint-Gilles/L’Ermitage lagoon, plus a Maido detour | 35-40 min each way |
| 3 | Cilaos: the spa town, the wine, the lentils | 1h15-2h from the west coast |
| 4 | Piton de la Fournaise, the caldera or the museum | 1.5-2.5h via Bourg-Murat |
Book these before you go
- Check Cilaos guesthouse availability , rooms are limited in a town this small
- Book a guided Piton de la Fournaise hike , useful if the caldera trail is open but you want a guide who knows the current route
- Book a canyoning trip near Cilaos , a genuine half-day activity distinct from the hiking above
- Compare rental cars on Discover Cars , the volcano road is a dead end with no bus service
Day 1: Saint-Denis, and an airport named for the wrong sport
Land at Roland Garros Airport (RUN), about 10km from Saint-Denis, named for the aviator Roland Garros, born on Reunion in 1888, first to fly solo across the Mediterranean in 1913, killed in WWI in 1918; the Paris tennis stadium borrowed his name a decade later, in 1928, because aviation was the celebrity sport of that moment. Walk Le Barachois, the seafront promenade with cannons still aimed at the ocean, then Rue de Paris for the 19th-century Creole mansions built on sugar money. Currency is the euro: Reunion is French, EU, eurozone, and outside Schengen and the EU VAT area all at once.
Day 2: The lagoon, and a village you can see but not drive to
Drive 35-40 minutes to Saint-Gilles-les-Bains and L’Ermitage for the one stretch of coast where swimming is not restricted, thanks to a protected coral reef inside the Réunion Marine Nature Reserve. Swimming and surfing have been banned across most of the open west coast since July 2013, following a serious shark-attack cluster the Centre Sécurité Requin still actively manages; the lagoon itself is the safe exception. Early risers should detour to the Maido viewpoint first, about an hour up, for a look into the roadless Cirque de Mafate before cloud cover arrives around 8am.
Day 3: Cilaos, 400 bends and a wine nobody expects
One paved road in, famous for more than 400 numbered hairpin bends, roughly 1h15-2h from the coast, leads down into a thermal spa town that also grows its own small pale lentils and produces Reunion’s only wine, a real Pinot Noir, Malbec, and Chenin from vines at 1,200 meters. Order rhum arrangé with dinner, rum aged with local fruit for months, and treat it as the trip’s actual souvenir.
Day 4: A caldera that was liquid rock months ago
Drive via Bourg-Murat and Plaine-des-Cafres toward Pas de Bellecombe, roughly 1.5-2.5 hours depending on your starting point, and check status first: Piton de la Fournaise erupted in three phases from 13 February to 12 April 2026, and the prefecture only returned the alert level to baseline “vigilance” on 7 May 2026, reopening two specific marked trails. When it is open, the crossing of the Enclos Fouqué lava plain to the crater rim runs about 4 hours one-way, roughly 10 hours for the full 14.5km round trip, walking across a floor that was molten within recent memory. When it is closed, the Cité du Volcan museum near Bourg-Murat covers the same geology for €9 adult, €6 child, with a €2 4D-cinema add-on, open Tuesday to Sunday, 9:30 to 17:00.
Is Piton de la Fournaise open for hiking right now?
Depends entirely on the current alert level, which changes with each new unrest episode, so treat any blanket “yes you can always hike it” claim as false. Check reunion-parcnational.fr or the prefecture’s own reunion.gouv.fr bulletin the day before you drive up, since the road itself stays open even when the caldera trail does not.
Is the shark ban going to ruin your beach day?
No. It applies to the open ocean past the reef, not to the protected Saint-Gilles/L’Ermitage lagoon where the water is calmest anyway, and where both locals and visitors actually swim. The rule only matters if you paddle out past the break looking for surf, which is not where this itinerary sends you.
Pack a warm layer for day 4 regardless of the caldera’s status; the rim sits at 2,311m, roughly 10-15 degrees cooler than the coast, and nothing about a “tropical island” itinerary prepares first-timers for that swing.
