Top Que Faire à Réunion — Complete Guide 2026
From walking on an active volcano to helicopter flights over roadless wilderness — the 20 best experiences on France's most dramatic island.
Why Réunion Is Unlike Anywhere Else
Réunion Island defies easy categorisation. It is simultaneously a tropical Indian Ocean island with palm-fringed lagoons, and a high-altitude volcanic wilderness where you can watch snow dust the summit of a 3,070-metre peak. It has the infrastructure and sophistication of France — excellent roads, superb food, reliable healthcare — wrapped in the warmth and rhythm of Creole culture. And unlike most tropical destinations that trade on beaches alone, Réunion's great asset is verticality: the entire island rises from sea level to over 3,000 metres in under 25 km as the crow flies, creating a density of extreme landscapes that is genuinely world-class.
This compact geography means you can snorkel in the lagoon at Hermitage in the morning, drive through sugarcane fields and tropical forest, and be hiking across a lava field at 2,300 metres by early afternoon. In a single week, you can summit the highest peak in the Indian Ocean, explore a roadless cirque accessible only on foot, watch molten lava glow against the night sky, and spot humpback whales breaching offshore. It is an island that rewards the active traveller — not someone looking for a beach-and-buffet holiday, but someone who wants to earn their views and end each day with a sense of genuine accomplishment. Here is everything you need to fill your Réunion itinerary in 2026.
1. Hike Piton de la Fournaise — Walk on an Active Volcano
Piton de la Fournaise is the crown jewel of Réunion's attractions and one of the most accessible active volcanoes on Earth. Erupting over 100 times in the last three centuries — with major eruptions in 2023, 2024, and continuing into 2025 — it is a shield volcano whose activity is characterised by relatively gentle lava fountains and effusive flows rather than explosive blasts, making it remarkably safe for guided visitation when conditions permit. The approach alone is an adventure: the Route des Laves (RN2) cuts across black lava fields from past eruptions, some of which reached the sea, and the final ascent to the Pas de Bellecombe viewpoint (2,311 m) passes through the surreal Plaine des Sables — a red, Mars-like expanse of volcanic ash and cinder that looks like another planet.
From Pas de Bellecombe, the 12 km return hike to the Dolomieu summit crater crosses the Enclos Fouqué caldera — an 8 km-wide depression formed by collapse after a massive eruption. The trail is marked with white painted dots on the black basalt and involves roughly 400 m of elevation gain and loss. You will pass the Formica Leo, a small but perfectly formed volcanic cone, and several fissure vents that have opened in recent eruptions. The terrain is raw and utterly barren: there is no vegetation, no shade, and no water anywhere on the route. At the crater rim, you stand above a 300-metre-deep chasm — when active, you can hear the rumble and see smoke rising from the depths. Always check eruption status at the Maison du Volcan in Bourg-Murat before setting out, as access roads close during elevated activity. Allow a full day from Saint-Pierre or Saint-Gilles, including the drive. Start hiking by 8 am to beat the afternoon cloud that frequently obscures the summit.
2. Trek the Cirque de Mafate — Réunion's Roadless Heart
Mafate is the largest and wildest of Réunion's three cirques — a colossal natural amphitheatre formed by the collapse of the Piton des Neiges shield volcano around 300,000 years ago. Its kilometre-high rampart walls encircle approximately 95 km² of deeply folded terrain, containing around a dozen tiny hamlets (îlets) whose 800 or so inhabitants live entirely off-grid: no roads, no cars, no power grid. Everything enters and leaves Mafate by foot, on the backs of porters, or by helicopter. To step off the road at the Col des Bœufs trailhead and descend into this world — where helicopters are the school bus and the only sounds are birds, streams, and the wind — is one of the most transporting travel experiences in the Indian Ocean.
The classic Mafate experience is a 3–5 day circuit connecting the main îlets: La Nouvelle, Marla, Roche Plate, and Aurère. Each night is spent in a gîte de montagne — rustic but comfortable dormitory-style accommodation where the host prepares a multi-course Creole dinner. The trails are well-maintained by the ONF, but this is serious hiking: daily elevation changes of 600–1,200 metres are normal, and total elevation gain over a full circuit exceeds 4,000 metres. The Crête des Calumets ridge between La Nouvelle and Marla offers one of the most spectacular views on the island — the entire cirque opening up below you with its rampart walls glowing gold in the afternoon light. Book all gîtes in advance (essential during July–August and October, when accommodation fills weeks ahead) and carry cash — there are no ATMs in Mafate.
3. Summit Piton des Neiges — The Roof of the Indian Ocean
At 3,070 metres, Piton des Neiges is the highest point in the Indian Ocean — higher than any peak in Madagascar, Mauritius, Seychelles, or the Maldives. This extinct volcano is the geological parent of Réunion itself, responsible for building the entire island through millions of years of eruptions before going dormant around 12,000 years ago. The summit is reached via a two-stage ascent that nearly every fit visitor to Réunion considers attempting.
The standard route begins in Cilaos and involves a 2–3 hour approach hike to the Caverne Dufour refuge (2,478 m), where hikers sleep in bunk beds before the summit push. Most departures from the refuge happen between 2 and 3 am — headlamps on, trekking poles clicking on volcanic rock — to reach the summit for sunrise. The final 90 minutes involve a steep scramble over loose scree, and at the top, in the predawn cold (temperatures can drop to -5°C in winter), you watch the sun rise over the Indian Ocean with the entire island spread out below. On exceptionally clear days, Mauritius is visible 175 km to the northeast. The descent is brutal on the knees, but the satisfaction — and the thermal baths waiting in Cilaos — make it worthwhile. Total distance from the Bloc car park: approximately 16 km return with 1,700 metres of elevation gain. Not for the unfit or ill-prepared: you need warm layers, gloves, a hat, 2+ litres of water, and sturdy boots.
4. Helicopter Tour Over the Cirques
If there is one splurge activity in Réunion worth every euro, it is a helicopter flight. No road penetrates the cirques from above, and from the ground you can only ever see one wall at a time. From the air, the full scale of the island's geology is revealed: the three cirques (Mafate, Salazie, Cilaos) side by side like giant paw prints, separated by razor-thin ridges; waterfalls spilling over 300-metre cliffs that look vertical from every angle; and the volcano massif in the distance, its caldera a black scar on the green landscape.
Several operators fly from Saint-Gilles and Saint-Pierre, including Corail Hélicoptères and Hélilagon. The classic 45-minute "Coeur de l'Île" (Heart of the Island) tour covers all three cirques and the volcano for around €280–350 per person. Longer tours include landings — one popular option drops you on a remote ridge in Mafate for a champagne picnic before flying back. Tours operate year-round but are weather-dependent; mornings generally offer the clearest conditions. Book several days in advance during peak season. This is also the only practical way to see Mafate if you lack the time or fitness for a multi-day trek. An unforgettable experience, and the photographs will be like nothing else in your travel collection.
5. Whale Watching Off the West Coast
Each year, between June and October, humpback whales migrate from their Antarctic feeding grounds to the warm, sheltered waters off Réunion's west coast to mate, calve, and nurse their young. This is one of the most reliably spectacular wildlife experiences in the Indian Ocean, with the peak season (August–September) producing daily sightings of breaching, tail-slapping, and spy-hopping whales, sometimes within sight of the Saint-Gilles shoreline.
Boat tours depart from the harbours at Saint-Gilles and Saint-Leu, typically lasting 2–3 hours. Operators are bound by the Réunion Whale Watching Charter, which mandates a respectful distance (minimum 100 metres) and prohibits chasing or harassment. Many operators employ marine biologists as guides, and the educational component adds real depth. The boats are small (typically 8–12 passengers), and the experience of hearing whale song through a hydrophone — or seeing a 15-metre, 40-tonne animal breach clear of the water — is unforgettable. Prices range from €60–90 per adult. Book in advance for August–September weekends. Even from land, the terrace at Iloha Seaview Hotel in Saint-Leu is a famous whale-watching spot — bring binoculars.
6. Night Volcano Viewing (Volcan la Nuit)
When Piton de la Fournaise is in an active eruptive phase — which happens roughly once to three times per year — one of the most extraordinary experiences on the planet becomes available: driving to the Pas de Bellecombe viewpoint after dark to watch lava fountains and flows illuminate the night sky. The contrast of orange-red molten rock against the black silhouette of the volcano and the star-filled sky above is mesmerising. Eruptions from this volcano are typically effusive (gentle lava flows rather than explosive), and the viewing area at Pas de Bellecombe is far enough from the active zone to be safe when access is permitted.
Eruptions are unpredictable, and access is controlled by the prefecture based on guidance from the Volcanological Observatory of Piton de la Fournaise (OVPF). During an eruption, the car park at Pas de Bellecombe fills quickly — if you are on the island when an eruption occurs, head up as soon as you hear the news. The website fournaise.info provides near-real-time eruption updates, webcam feeds, and access status. Bring warm clothes (it can be very cold at 2,311 m even in summer), food, water, and a full tank of fuel — there are no services at the top. This is a once-in-a-lifetime experience if the volcano happens to be active during your visit; it is worth reorganising your entire itinerary around.
7. Explore the Cilaos Cirque & Thermal Springs
Cilaos, sitting at 1,214 metres in a high volcanic bowl, is reached via the RN5 — a road with over 400 hairpin bends climbing from the coastal town of Saint-Louis. The drive alone is an attraction, with views improving at every switchback until you crest the rim and the cirque opens before you. The town of Cilaos is a charming mountain settlement famous for three things: lentils (lentilles de Cilaos, a protected French product with a unique volcanic terroir), wine (one of France's highest vineyards, producing crisp whites from Chenin and Pinot Noir grapes grown on terraced slopes at 1,200 m), and thermal springs (used since the 19th century for their reputed therapeutic properties).
The thermal baths at the IRT (Institut de Rééducation Thermale) are open to visitors for relaxation soaks, with water emerging from the source at 32°C and rich in mineral salts. Beyond the town, hiking trails radiate in every direction: the Roche Merveilleuse viewpoint offers a breathtaking panorama of the cirque walls, the Bras Rouge waterfall is a 2-hour return walk through highland forest, and — for the ambitious — the Piton des Neiges trailhead starts near the Bloc car park. Cilaos also makes an excellent base for cooler nights (temperatures are typically 8–10°C lower than the coast) and the restaurants here specialise in hearty mountain cuisine: lentil soup, smoked pork, gratin de chouchou, and local wine pairings.
8. Snorkel the Hermitage Lagoon
Réunion has relatively few beaches — it is a young volcanic island without the extensive fringing reefs of older Indian Ocean islands — but what it does have is precious. The lagoon at L'Hermitage-les-Bains, just south of Saint-Gilles, is the island's finest stretch of protected water: a 7 km band of shallow, turquoise sea sheltered from the open ocean by a coral reef. The water is calm, warm (24–28°C year-round), and teeming with tropical fish — parrotfish, butterflyfish, Moorish idols, and the occasional turtle. It is ideal for families, novice snorkellers, and anyone wanting a gentle introduction to Indian Ocean marine life without the commitment of a boat trip.
The beach itself is shaded by filao (casuarina) trees — a godsend in the tropical sun — and the sand is a mix of white coral and dark volcanic grains that gives it a distinctive charcoal-flecked appearance. Facilities are good: parking, showers, lifeguards during peak periods, and beachside snack bars selling samoussas, cold drinks, and ice cream. For more serious snorkelling, the reef pass at Trou d'Eau (further south near La Saline-les-Bains) has better coral and larger fish, but stronger currents — best attempted with flippers and confidence. The lagoon is swimmable year-round, but September–November offers the best combination of warm water, low rainfall, and minimal cyclone risk.
9. Vanilla Plantations & the Wild East
Réunion's east coast — the windward side — is a completely different world from the sunny, dry west. Here, the trade winds deposit their moisture against the mountains, creating a rainforest environment of staggering lushness. The coast between Saint-Benoît and Sainte-Rose, along the Route des Laves, is where the island's vanilla industry is concentrated. Réunion is the original home of Bourbon vanilla (the name comes from the island's pre-revolutionary name, Île Bourbon), and the vanilla grown here — hand-pollinated, sun-cured for months, and dark as mahogany — is among the finest in the world.
The Domaine du Grand Hazier near Sainte-Suzanne is one of the best vanilla plantations open to visitors. The guided tour (approximately 1 hour, €8–12) explains the fascinating and labour-intensive process: each vanilla orchid flower must be hand-pollinated within a single morning window, the green beans are then blanched, sweated, and sun-dried over a period of months, and the final transformation from green pod to aromatic black vanilla is a slow miracle of patience. The shop sells vacuum-packed vanilla pods, vanilla extract, and vanilla-infused products at excellent prices compared to European retail. Nearby, the Jardin des Parfums et des Épices (Garden of Perfumes and Spices) in Saint-Philippe is another excellent stop, with guided walks through plantations of cinnamon, nutmeg, clove, turmeric, and ylang-ylang — a full sensory tour of the island's spice heritage.
10. Saint-Denis: Creole Architecture, Markets & Museums
The capital, Saint-Denis, rewards at least a full day of exploration. The architectural highlight is Rue de Paris, a grand boulevard lined with exquisitely preserved Creole colonial mansions (cases créoles) from the 18th and 19th centuries. These timber-built houses — with their wrap-around verandas (varangues), louvred shutters, and intricate fretwork — are a distinctive architectural form evolved to handle the tropical climate. Several are open to the public, including the Maison Carrère (free entry), which has been restored to show how the island's planter elite lived in the 1820s.
The Grand Marché (Big Market) on Rue du Maréchal Leclerc is a bustling hall of stalls selling vanilla, spices, handmade textiles, woven hats, and crafts — an excellent place for souvenirs. The Petit Marché nearby handles fresh produce and food stalls. Art lovers should visit the Musée Léon Dierx, housed in a former bishop's palace and holding one of the best collections of 19th and 20th-century French art in the Indian Ocean (works by Gauguin, Picasso, and Renoir, among others). The Barachois — the seafront promenade — is perfect for a sunset stroll, with cannons from the British era pointing out to sea and views toward Madagascar 680 km away.
11. Waterfall Chasing in the Cirque de Salazie
Salazie is the wettest and greenest of Réunion's three cirques, accessible by road via the village of Salazie and continuing to the beautifully preserved spa village of Hell-Bourg (officially classified as one of France's Plus Beaux Villages). The cirque is a vertical world of waterfalls — at least a dozen significant cascades are visible from the main road, with the most spectacular being the Voile de la Mariée (Bride's Veil), a multi-stranded waterfall that fans out across a high cliff face like a wedding veil. The viewpoint is directly accessible from the road, no hiking required.
For the more adventurous, the trail to the Trou de Fer (Iron Hole) leads to one of the most dramatic viewpoints in the Indian Ocean — a vast collapsed chasm where multiple waterfalls plunge over 300 metres into a misty abyss. Access is via a well-maintained trail from the Gîte de Bélouve (approximately 3 hours return, moderate difficulty). The primary rainforest here — the Forêt de Bélouve — is a UNESCO World Heritage site and one of the best-preserved examples of tropical montane cloud forest anywhere in the Indian Ocean, with ancient tree ferns, moss-draped branches, and endemic birds. The track can be muddy, even in the dry season — proper footwear is essential.
12. Drive the Wild South Coast
The stretch of coast from Saint-Pierre to Saint-Philippe, via the towns of Petite-Île and Saint-Joseph, is Réunion's wild south — a dramatic coastline of black volcanic cliffs, sudden deep ravines, and powerful surf crashing against basalt platforms. This is not swimming territory (the sea here is rough and dangerous), but it is spectacular to drive. The highlight is the Cap Méchant (Wicked Cape) viewpoint, where waves explode against black lava cliffs and the wind whips spray across the viewing platform. The contrast — lush sugarcane fields on one side, violent ocean on the other — is pure Réunion.
Continue to Grande Anse, the south coast's only swimmable beach (a sheltered cove with a natural swimming pool at low tide) and the excellent Palm Hotel & Spa, which offers fine dining with Indian Ocean views. The Jardin des Parfums et des Épices near Saint-Philippe is a worthy detour, and from there you can loop back up the Route des Laves (RN2) through Sainte-Rose and the volcano approach road, completing a magnificent full-day circuit of roughly 150 km. Alternatively, continue north via the RN2 for the equally dramatic lava coast between Sainte-Rose and Saint-Benoît, where lava flows from the 1977 eruption destroyed much of the village of Piton Sainte-Rose — the church (Notre-Dame des Laves) miraculously survived, with lava flowing around it and stopping at the doorstep.
