Backpacking in Conservatoire Botanique National de Mascarin
👌 Worth visitingattraction ranked #6
By Johan Kruseman 🇳🇱 | Updated October 22, 2026

The Mascarin garden sits on a slope above Saint-Leu, and the first thing you notice is the sound: a trickle of water running through channels between beds of endemic plants, with the creak of old trees overhead. The Conservatoire Botanique National de Mascarin is in the west of Réunion, on the hillside above Saint-Leu, a short drive from Saint-Gilles. It protects rare island species, so paths are neat, labeled and shaded, and the air smells of damp earth and frangipani. Midday gets sticky because the site is lower and drier than the highlands, so go in the morning and carry water. The grounds are calm even on busy weekends, and the entry fee is modest. Unlike the Jardin d’Eden at Saint-Gilles, which leans toward ornamental display, Mascarin is a working conservation center where the science is the point.

✨ Why go?
Ranked #6 attraction in Réunion
The unique appeal for travelers

Conservatoire Botanique National de Mascarin is the place to meet the island’s endangered native plants without a hike into the cloud forest. Many of the species here grow wild only in Réunion and nearby Indian Ocean islands, and some survive in just a handful of locations, so labels give you a real sense of what the volcanic mountains hide. The garden also holds a historic colonial house from the sugar era, which adds a human story to the botanical one. It makes a calm break between beaches and the demanding trails of the Cirques, and suits anyone who likes slow wandering. If you are traveling the west coast, the Mascarene endemic collections help you recognize plants later on the Maïdo road, and the seed conservation work gives the rest of the trip a clear purpose.

  3. Palm collection: Tall Mascarene palms create a canopy, giving some of the best shade on the site.

🌤️ When to go?Choosing the right time of year

  • Austral Winter (May to October): Dry, mild and the easiest time to walk the garden. Days run 18 to 24°C (64 to 75°F) at this 100 m elevation near Saint-Leu, with cooler nights and clear mornings. Daylight lasts roughly 11 hours, so arrive early.
  • Summer (November to April): Hot and humid at 26 to 32°C (79 to 90°F), with afternoon downpours and a cyclone risk from January to March. Flowering is lush, but paths turn slick and midday heat is heavy.
  • School Holidays (July to August, December to January): Local families fill the grounds on weekends and prices for nearby rooms and rental cars climb.
  • Shoulder Months (May, June, September, October): Quiet paths, good light and the lowest rates for rentals and rooms.
Arrive at opening on a weekday morning, when the air is cool and the tour groups have not yet arrived.

🛏️ Where to stay?Best areas to stay in Réunion

Saint-Gilles-les-Bains is the best base for backpackers, about 25 to 30 minutes by car or a short bus ride from the garden. It has the island’s densest cluster of hostels, guesthouses and cheap apartments, plus surf shops, a lively harbor and evening bars where solo travelers meet easily. Walking back at night feels safe along the main strip, and the lagoon beaches at L’Hermitage are close.

Walking back at night feels safe along the main strip, and the lagoon beaches at L’Hermitage are close.

Saint-Leu is the quieter alternative, much nearer the Conservatoire. It suits those who want a relaxed coastal village with paragliding launches above town, a small beach and fewer crowds. Social options are fewer, but guesthouses here tend to be friendly and good for chatting with locals.

Les Avirons and the highland villages above Saint-Leu offer simple gîtes with cool nights and garden views. They are peaceful and cheaper, but you will want your own wheels, as evening buses are rare.

Saint-Pierre in the south has a livelier nightlife and a large market, though it is a longer drive. For most travelers, Saint-Gilles combines the best nightlife, transport links and company, with Saint-Leu as the practical pick for early starts.

We 💚 feedbackSumming up the experience

Conservatoire Botanique National de Mascarin suits plant lovers, slow walkers and anyone needing a shaded break from beach days or tough trail days. If you only care about adrenaline, skip it. I would come early, bring a hat and water, and read the labels, because the best moments come from the rare species.
