3 Days in Reunion: The First-Timer Itinerary
Three days is the shortest trip that earns the name “Reunion Island itinerary” instead of “beach weekend with a French accent.” You get the west-coast lagoon, one cirque, and a caldera hike on one of the most active volcanoes on Earth. That third day, Piton de la Fournaise, is what separates this from the 2-day version, and it is worth every hour of driving to reach it.
Getting around Reunion in 3 days
A rental car is not a suggestion here, it is the trip. The island’s interior is a mountainous volcanic massif with the coast, three cirques, and the volcano each behind their own single approach road. Discover Cars has counters right at Roland Garros; book ahead if you are flying in during July-August, December-January, or the mid-October Grand Raid ultramarathon week, when rates spike islandwide.
Route summary: Saint-Denis to Saint-Gilles (about 35-40 minutes), up to Cilaos (roughly 1h15-2h) via 400-plus hairpin bends, then back down and across to Pas de Bellecombe for the volcano (allow 2-2.5 hours from the Cilaos area). Coming from the 2-day plan ? This is the exact same base plus one huge extra day. Ready for more cirques, add the 4-day itinerary , or jump straight to the full 7-day loop . The places page ranks every sight by how much time it deserves.
Book these before you go:
- Lagoon-side rooms: Saint-Gilles-les-Bains hotels
- A night in the cirque: Cilaos stays
- A guided caldera hike: Piton de la Fournaise volcano tour
- Your rental car: Discover Cars at Roland Garros
Day 1: Saint-Denis and the Saint-Gilles lagoon
Land at Roland Garros, named for the aviation pioneer, not the tennis stadium, and grab your car. Give Saint-Denis an hour: Le Barachois waterfront and the Creole mansions on Rue de Paris, both on the official tourism site , cost nothing to walk past. Drive on to Saint-Gilles-les-Bains and get in the water at the protected lagoon, the one stretch of west coast where swimming has never been banned. Everywhere else on that coast has been off-limits for open-water swimming and surfing since 2013, after a real shark-attack cluster, so stay inside the reef.
Day 2: Cilaos, up the 400 bends
The mountain road into Cilaos earns its reputation before you have finished the first dozen switchbacks. It’s inside the Parc national de La Réunion , so check current trail conditions there before any side hike. Once you arrive, this is a genuine spa town: thermal baths running since the 19th century, Reunion’s only wine region (Chenin, Pinot Noir, Malbec), and the small pale lentils grown around Ilet a Cordes. Overnight here so tomorrow’s volcano drive starts from the south, not the coast.
Day 3: Piton de la Fournaise, the active volcano
This is the marquee day. Piton de la Fournaise erupted across three phases into 12 April 2026, and the OVPF’s daily bulletin had it back at the baseline “Vigilance” level as of its 2 July 2026 update, with marked trails open from the Pas de Bellecombe car park (2,311m). Always check the live status before you drive out; access opens and closes with each new alert. National park entry is free. Hike out across the Enclos Fouqué lava plain toward the crater rim, roughly 4 hours one way if you’re going the distance, and stop at the Cité du Volcan museum on the way (EUR 9 adult, EUR 6 child, Tuesday-Sunday, last entry 16:15) if the trail itself is closed.
| Day | Focus | Drive/hike time |
|---|---|---|
| Day 1 | Saint-Denis + Saint-Gilles lagoon | ~35-40 min drive |
| Day 2 | Cilaos cirque, overnight | ~1h15-2h drive |
| Day 3 | Piton de la Fournaise volcano | ~2-2.5h drive, 4h+ hike |
Is the volcano always open to hike?
No. Piton de la Fournaise is genuinely active, not a scenic backdrop, and the caldera closes to the public every time the alert level rises. It reopened after the last eruption ended in April 2026, but that can flip again with no notice. Never build a 3-day trip around one specific hike without a same-week check of the OVPF bulletin.
Do I need a guide for the caldera hike?
Not legally, the self-guided trail from Pas de Bellecombe is well marked and free to enter. A guided hike, roughly EUR 50-100pp, adds context on the lava fields and a second set of eyes on fast-changing mountain weather, worth it if you’ve never hiked at 2,000m-plus before.
Confirm the volcano’s current alert status the night before you drive out; a 2.5-hour trip to a closed trailhead is the one way to waste your best day on this itinerary.
