Reunion Island Travel Guide —
France's wildest island hides a living volcano, three impossibly green cirques

Réunion Island rises from the Indian Ocean like a fever dream — a jagged volcanic mass draped in cloud forest, where waterfalls plunge three hundred metres into cathedral-quiet cirques and the air smells of wild ginger and eucalyptus. The island's centrepiece, Piton de la Fournaise, is one of the world's most active volcanoes, erupting several times each year with brazen regularity, painting lava flows across a moonscape of basalt. Down in the valleys, Réunion is unmistakably French: fresh baguettes appear on mountain refuge breakfast tables, wine costs the same as in Lyon, and the administrative efficiency is reassuringly European. Yet Réunion is simultaneously Malagasy, Indian, Chinese and Creole — a cultural fusion that transforms every market stall and every kitchen into something wholly its own.

What makes visiting Réunion different from Mauritius or the Maldives is the complete absence of the beach-resort template. Things to do in Réunion skew dramatically towards the physical and the authentic: multi-day trekking circuits, canyoning in basalt slot canyons, surfing waves that have crossed the entire Indian Ocean, and sitting down to a proper rougail saucisses with a Creole family on a Sunday afternoon. The island is French territory, which means EU standards on food safety, roads and hospitals, but Indian Ocean prices on rum, vanilla and accommodation in family-run gîtes. Travellers who discover Réunion rarely compare it to other islands — they compare it to the best adventure they have ever had.

Your Reunion Island itinerary — choose your style

Why Reunion Island belongs on your travel list

Réunion belongs on your travel list because it solves a problem most travellers don't know they have: the desire for genuine wilderness within a framework of European comfort and safety. The island contains three UNESCO World Heritage cirques — Cilaos, Mafate and Salazie — each an amphitheatre of collapsed caldera walls so steep that Mafate is accessible only on foot or by helicopter. Réunion's volcano is not a dormant postcard backdrop but a living geological event you can hike to the rim of legally and freely. Add world-class surfing at Saint-Leu, vanilla plantations in Bras-Panon, and one of the most complex Creole cuisines on the planet, and Réunion becomes almost unfairly compelling.

Top things to do in Reunion Island

1. #1 Hike to Piton de la Fournaise

Standing at the rim of one of the planet's most active shield volcanoes is the defining experience of any Réunion itinerary. The standard approach begins at the Pas de Bellecombe car park at 2,311 metres, from where a clearly marked trail descends into the Enclos Fouqué caldera — a vast silvery-black basin of solidified lava — before climbing to the Formica Léo crater and then, weather permitting, all the way to the Dolomieu crater rim at 2,631 metres. The round trip takes five to seven hours and requires no technical climbing, but you should check the OVPF (Observatoire Volcanologique du Piton de la Fournaise) website before setting out, as access is suspended during eruptions. If you arrive during an active eruption, positions on the southern rim legally open for supervised viewing — an experience that is genuinely rare anywhere in the world. Bring layers, as temperatures at the summit can drop sharply within minutes.

2. #2 Trek Through Cirque de Mafate

Mafate is Réunion's most audacious geographical feature: a collapsed caldera so steep and so remote that no road has ever been built into it. Its handful of hamlets — Îlet à Malheur, La Nouvelle, Marla, Roche Plate — are accessible only by foot or helicopter, and their Creole residents have developed a culture of extraordinary self-sufficiency. The classic approach is the Col des Boeufs pass from Hell-Bourg in Salazie, a three-to-four-hour descent into the cirque floor. Most trekkers spend two to four nights in gîtes de montagne, simple mountain lodges that include dinner and breakfast — typically a Creole rice-and-rougail spread that you will dream about for months. The GRR2 long-distance trail threads across the entire island and passes through Mafate; experienced hikers can combine all three cirques over eight to ten days in one of the most satisfying trekking circuits in the Southern Hemisphere. Book gîtes well in advance during June to September peak season.

3. #3 Canyoning the Gorges de la Rivière des Galets

Réunion has developed a deserved reputation as one of the best canyoning destinations in the world, and the Rivière des Galets gorge system on the western approach to Mafate is the island's most thrilling introduction to the sport. Basalt walls narrowed by millennia of volcanic erosion create a series of natural water slides, abseil sections and plunge pools that professional guides navigate with cheerful efficiency. Operators based in Saint-Paul and Saint-Gilles offer half-day and full-day descents graded from beginner to expert, with all equipment included. The Canyon de Fleur Jaune and the Trou de Fer descent in Salazie are considered the island's two most spectacular routes for experienced canyoners. Réunion's canyons run year-round, but water levels are safest and most enjoyable between June and October during the dry season. This is a region where the infrastructure for adventure sports is genuinely world-class, rivalling established centres in New Zealand and the Swiss Alps.

4. #4 Drive the Route des Laves

The Route des Laves (RN2) on Réunion's eastern coast is one of the most geologically spectacular drives on any island in the world. The road hugs the shoreline south of Saint-Philippe, passing directly over ancient and recent lava fields where black basalt meets turquoise ocean in a collision of textures that feels frankly extraterrestrial. Interpretive panels and pull-offs mark the points where lava flows from Piton de la Fournaise reached the sea in various historical eruptions, some as recently as 2020. The Souffleur marine blowhole near Le Baril shoots jets of sea spray through a lava tube ceiling with each incoming wave. Continue south to the Pointe de la Table lighthouse, then complete the loop through the fragrant forests of the Grand Sud interior, stopping at the village of Saint-Joseph for a buckwheat chilli sandwich from a roadside stall. Allow a full day for the circuit and pair it with a stop at the Maison de la Vanille in Bras-Panon on the way back north.

Getting to and around Reunion Island (Transport Tips)

By air: Réunion's Roland Garros International Airport (RUN) near Saint-Denis receives direct flights from Paris Charles de Gaulle (Air Austral, Air France, Corsair) in approximately eleven hours. Connections via Mauritius, Mayotte and Johannesburg serve other European cities. Flights from Paris are frequent and competitively priced when booked three to four months ahead.

From the airport: Roland Garros Airport sits eight kilometres east of Saint-Denis. Taxis to the capital cost €15–25 and take fifteen minutes. Car hire desks operate inside the arrivals hall — all major European companies are represented — and renting a vehicle from day one is strongly recommended as public bus coverage is limited outside the northern coastal strip. Pre-book during June to September peak season.

Getting around the city: Réunion's Car Jaune bus network covers the coastal ring road and major interior routes reliably and cheaply, but frequencies drop sharply in evenings and on Sundays. A rental car is effectively essential for reaching the volcano plateau, Cilaos cirque road and any meaningful inland exploration. Taxis are metered, affordable by European standards, and available in all main towns. Mafate is accessible exclusively on foot or by helicopter from Saint-Paul or Saint-Leu.
