How many days do you need in Reunion?
Reunion requires 7 days to truly experience its dramatic landscapes. Four days allows a quick taste of the volcanic peaks, but a week is essential to properly explore the three immense cirques—Mafate, Salazie, and Cilaos—and hike the active Piton de la Fournaise volcano without rushing through the winding mountain roads.
Short answer
4 days
Focus on the essentials. Drive up to Piton de la Fournaise for a lunar hike across the Plaine des Sables. Explore the lush waterfalls of Grand Galet in Saint-Joseph and spend a day walking through the Creole village of Hell-Bourg in the verdant Salazie cirque.
You give up: You sacrifice the deep, trail-only wilderness of Cirque de Mafate, coastal helicopter tours, and relaxing on the black sand beaches of Etang-Salé.
7 days
Tackle the legendary hike up Piton des Neiges, the highest peak in the Indian Ocean. Explore the steep hairpin turns leading to the Cilaos cirque for thermal baths and local lentil tasting. Spend leisurely afternoons kite-surfing in Saint-Pierre and discovering Saint-Denis architecture.
You give up: You miss out on multi-day backcountry trekking and fully exploring the wild eastern windward coast's rainforests and lava tubes.
10 days
Slow down and add a dramatic helicopter flight over the inaccessible interior. Enjoy multi-day hiking across Cirque de Mafate, stay in remote mountain gîtes, and thoroughly explore the Takamaka gorge and Le Tremblet lava flows on the untamed wild south coast.
You give up: Nothing missed; this duration covers all major geographical highlights, coastal towns, and immersive cultural experiences available on the island.
If you can stay longer
An extra 2-3 days unlocks a full day trip to neighboring Mauritius for contrast, or allows you to spend 48 immersive hours deep inside Cirque de Mafate where no cars go. You can also dedicate a full day to exploring the subterranean lava tunnels at Sainte-Rose and whale watching from Saint-Gilles-les-Bains.

Common questions
When is the best time to visit Reunion?
The best time is between May and November during the southern hemisphere's dry winter. Temperatures are comfortable for hiking, coastal humidity is lower, and rainfall in the mountain cirques like Cilaos and Salazie is significantly reduced compared to the hot, wet cyclone season from January to March.
Do I need to rent a car?
Renting a car is absolutely essential because public buses are infrequent and do not reach the trailheads or mountain viewpoints efficiently. The roads are well-paved but extremely steep and winding, requiring confident driving skills, especially when navigating the hundreds of hairpin bends into Cilaos.
Is hiking suitable for beginners?
Reunion is a world-class hiking destination, but the terrain is notoriously steep, rugged, and physically demanding. While there are short coastal walks and family-friendly paths in Salazie, most trails into the cirques and up Piton de la Fournaise require a strong fitness level and proper mountain preparation.
