Reunion Island: What Most Visitors Miss
Reunion Island is a French overseas department, not a country and not part of Mauritius, a separate nation roughly 175km away that most people confuse it with. It is also home to one of the most active volcanoes on Earth, a village of 800 people you can only reach on foot or by helicopter, and a west coast where swimming is legally banned outside one protected lagoon. None of that fits the generic “tropical getaway” pitch, which is exactly why most first-time visitors miss all of it.
| Sight | Area | Why go | Access |
|---|---|---|---|
| Cirque de Mafate | Interior highlands | 800 people, zero roads, reached only by trail or helicopter | Multi-day hike from a coastal trailhead, or a helicopter overflight |
| Piton de la Fournaise | South-east | An active volcano with a walkable lava-plain caldera, when open | Drive to Pas de Bellecombe, hike status-dependent |
| Cirque de Cilaos | Interior highlands | Thermal spa, Reunion’s only wine, 400-plus hairpin bends to get there | One paved road in, roughly 1h15-2h from the coast |
| Hell-Bourg, Cirque de Salazie | Interior highlands | Carved Creole houses, a “Plus Beaux Villages” listing | One switchbacked road in, no faster alternative |
| Trou de Fer | Between Salazie and Bélouve | A multi-tier waterfall gorge, mostly a helicopter-only view | Partial hiking viewpoint from the Gîte de Bélouve, full view by air |
| Piton des Neiges | Interior, via Cilaos | 3,070m, the highest point in the Indian Ocean, extinct and separate from the Fournaise | 2-day hike with an overnight at the Gîte de la Caverne Dufour |
| Saint-Gilles/L’Ermitage lagoon | West coast | The one stretch of coast where swimming is not restricted | 35-40 min drive from Saint-Denis |
| Le Barachois, Saint-Denis | North coast, the capital | Free colonial-era waterfront and 19th-century Creole mansions | Walkable in the capital |
The village nobody drives to
Cirque de Mafate is the strangest thing on this list: a natural amphitheater with roughly 800 residents scattered across hamlets like La Nouvelle, Marla, and Roche-Plate, and genuinely no road reaching any of them. Everything in and out moves on foot or by helicopter. The Maïdo viewpoint, about an hour’s drive up from Saint-Paul, is the easy way to look down into it without hiking, best before 8am when cloud typically rolls in; the real way in is a multi-day hut-to-hut trek, staying in gîtes along the way.
A volcano that erupts on a schedule most tourists never check
Piton de la Fournaise erupted across three separate phases between 13 February and 12 April 2026, and access to the Enclos Fouqué caldera opens and closes with the prefecture’s alert level, not with anyone’s travel dates. The Parc national de La Réunion posts current status, and it is worth checking the day before, not the week before. When it is open, the crossing of the lava plain to the crater rim takes about 4 hours one-way across ground that was molten rock within recent memory. When it is closed, the Cité du Volcan museum near Bourg-Murat covers the same geology for €9 adult, €6 child.
Lentils, wine, and a road with 400 numbered bends
Cirque de Cilaos is reached by exactly one road, famous for more than 400 numbered hairpin bends dropping into a genuine thermal spa town. It also grows its own small, pale lentils around Ilet à Cordes and produces Reunion’s only wine, a real Pinot Noir, Malbec, and Chenin from vines at 1,200 meters, a fact that surprises people who assume French wine country stops at the mainland. Order a glass of rhum arrangé, rum aged for months with local fruit, while you’re there; it travels home better than the wine does.
Is Reunion Island part of Mauritius?
No. Reunion is a French overseas department and part of the EU and eurozone; Mauritius is a fully independent nation roughly 175km to the northeast. Both are former Mascarene sugar islands with a French colonial layer, which is where the confusion starts, but Mauritius was ceded to Britain in 1810 and became independent in 1968, while Reunion stayed French and remains so today. They are separate countries with separate governments, currencies in name only since both now use different systems, and no administrative link at all.
Is it safe to swim anywhere on the west coast?
Only inside the marked, protected lagoon zones, Saint-Gilles/L’Ermitage chief among them, a rule enforced since a serious shark-attack cluster led to a swimming and surfing ban across most of the open west-coast ocean starting in July 2013. It is a real, state-enforced measure, not internet scaremongering: the Centre Sécurité Requin runs active drone surveillance and shark tagging to manage the risk. Inside the lagoon, the water is calm, warm year round, and exactly where locals actually swim.
What the coast forgets to mention about the capital
Saint-Denis gets treated as a layover between the airport and everywhere else, but Le Barachois, the old seafront promenade, still has cannons facing an ocean it hasn’t had to defend against in decades, and Rue de Paris holds 19th-century Creole mansions, Maison Carrère among them, built on the 19th-century sugar boom. Both are free to see and skipped by nearly everyone racing toward the cirques.
Compare Saint-Gilles beach hotels for the coast, or book a Mafate and Fournaise helicopter flight for the one sight on this list that a rental car will never reach. Our 2 day weekend covers the coast alone, and the 7 day itinerary is the version that gets to Mafate’s viewpoint, the volcano, and the Piton des Neiges summit in one trip.
