Butterflies, an ant colony and botanical trails show different sides of Saint-Léons. There is also the birthplace of the entomologist Jean-Henri Fabre, historic buildings and a viewpoint overlooking the Grands Causses. This gives you a choice of different things to focus on when planning your visit: entomology, circular walks and cultural heritage.
Insect Worlds at Micropolis and in the Garden
An indoor visit to Micropolis includes a tropical butterfly house and a giant ant colony. The chemin de la biodiversité at Micropolis includes four biodiversity features: la Toubière, les Haies des proies & des prédateurs, le Coin des recycleurs and l’Allée aux papillons (& autres butineurs...). Each stop has a different thematic focus—from the bog and predator-prey relationships to recycling, butterflies and other pollinators.
The Jardin d’insectes dit du perce-oreille is free to enter and open year-round. Insects are presented there in settings including the vegetable garden, orchard, pond, compost area and woodpile; information panels explain their importance. The two offer distinct experiences: Micropolis, with its butterfly house and ant colony on an indoor visit, and the insect garden, with its different garden areas and information panels.
Botanical Trails and Walks
The Sentier botanique de St-Léons is a 2.5 km circular route that takes about two hours. Around 30 signs beside trees from different natural habitats give the walk its botanical focus. The educational trail is freely accessible all year round.
Another option is La balade de Jean-Henri Fabre: this 3.5 km family walk around Saint-Léons starts at Micropolis and takes you to Micropolis, the botanical educational trail, the insect garden and Jean-Henri Fabre’s birthplace. You can choose between a botanical walk with an approximate duration and a route described as a family walk. The route Sur les pas de Jean-Henri Fabre starts at the Micropolis car park in Saint-Léons.
Jean-Henri Fabre, Heritage and Landscape
The Maison Natale de Jean-Henri Fabre shows the surroundings where the entomologist spent his childhood. An adjoining exhibition room houses a collection of preserved insects. In a statement dated 18 December 2025, the French Ministry of Culture named the birthplace as a recipient of the “Maison des Illustres” label.
The buildings also offer their own historical highlights: Fort Bas is a standalone building that was fortified at the end of the Middle Ages. The Dolmen Peyrelevade measures approximately 5 m × 3.4 m. The Peyrelevade site also offers a viewpoint over the surrounding Grands Causses. Saint-Léons itself is built in an amphitheatrical layout on a hillside; its shape reflects the village’s position in the terrain, while the viewpoint looks out over the landscape.
Geocaching and Electric Mountain Bikes
When geocaching in Saint-Léons, use your smartphone to search for hidden caches in the village. Before setting out, check that the app and caches are available. For this activity, park opposite the tourist office and continue on foot.
Location de VTT électrique à la Pierre Pointue offers electric mountain bikes for exploring Saint-Léons and its surroundings; confirm availability before your trip. Guided electric mountain bike rides are offered at Pierre Pointue by reservation. Check their availability in advance, too.
