YOUR HOLIDAY. COMFORTABLY DIFFERENT.
Sea and landscapes.
Time in between.
Réunion combines tropical shores with a mountain region that requires a different holiday rhythm. In southern winter, stay several days on the west coast before spending time in Cilaos beneath steep cirque walls.
Réunion combines tropical shores with a mountain region that requires a different holiday rhythm. In southern winter, stay several days on the west coast before spending time in Cilaos beneath steep cirque walls.
Saint-Gilles and Saint-Leu provide different coastal bases. A permitted lagoon area, a cultural visit and a day without a large programme are enough. Swimming freely along every shore is not an appropriate itinerary.
Cilaos deserves nights of its own. The winding approach and temperature change make it more than a quick photograph stop. Choose strolls and shorter open paths for your experience; summit ascents are outside this guide.
Which region does this guide cover?
Covers the western coastal area from Le Port and Saint-Paul through Saint-Gilles-les-Bains, Ermitage and La Saline to Saint-Leu, including suitable cultural and garden visits. Includes the approach through Saint-Louis to Cilaos and the inhabited cirque with selected open shorter paths, Bras Sec and Roche Merveilleuse. Saint-Denis serves only arrival, not a sightseeing itinerary. Mafate, Salazie, Maïdo, the Piton des Neiges summit, high-mountain treks, Piton de la Fournaise, the east coast, Sud Sauvage and an all-island circuit are excluded.

Reisezeit.
A regional perspective.
May to October falls in southern winter. Shores remain pleasantly warm while higher locations are cooler. The west is drier than the windward east, though rain and closures remain possible. November to April is warmer and wetter. Le Port is a coastal lowland reference, chosen to represent shores honestly rather than to provide temperatures for Cilaos.

A little planning.
Lots to look forward to.
Is Réunion an independent country?
No, it belongs to France. It is listed as a geographical territory with ISO code RE.
Which season is the focus?
May to October, southern winter; elevation and daily weather still matter.
Is a day enough for Cilaos?
Separate nights are preferable if the town and suitable walks form part of your trip.
Is Piton des Neiges included?
No. Summit ascents and high-mountain treks are excluded.
Can I swim everywhere?
No. Use only currently permitted areas and follow supervision, local advice and sea conditions.
Does the climate table describe Cilaos?
No. Le Port is deliberately coastal; the higher mountain town requires separate interpretation.
