The Mille Fleurs Botanical Trail starts at Petit Pré and ends at La Grand-Garde.

A magnificent round trip of approximately 2 hours and 30 minutes.

Petit Pré ➔ La Seya ➔ La Grand-Garde ➔ Petit Pré

From Petit Pré, beneath the light shade of the larch trees, the trail bordered by countless flowers climbs steadily with beautiful energy. After a few efforts, it leads you to the highest point of the La Seya botanical trail (2,182 m), where the Camille Cross stands proudly. Rising like an 8-metre sentinel, it offers a breathtaking 360° panorama. It is the perfect spot to admire and identify the Muverans mountain range, the Haut de Cry and the Alps thanks to the two orientation tables. Enjoy a contemplative break on the benches awaiting you there before continuing your hike to La Grand-Garde (2,146 m), where the Mille Fleurs Botanical Trail comes to an end. The return journey follows the same route back.

From La Grand-Garde, continue your adventure along the Tour de la Seya trail via Quieu, Odonne and Ovronnaz. Alternatively, follow the signposted “Brégneux Variant” along the forest road. In the cool shade of the larch trees, continue towards Odonne before finally reaching Ovronnaz. 💡 At Brégneux: Enjoy an exceptional viewpoint over the Rhône Valley! 📸 Allow around 2 hours from La Grand-Garde to return to the chairlift departure point.

At La Grand-Garde, a small secured lookout balcony opens onto a spectacular view. A wooden cross was erected there in 2019 in memory of three seminarians from the Écône church who lost their lives in an avalanche in 2009. In this majestic setting, the memorial transforms the end of the Mille Fleurs Botanical Trail into a place of peace and silence, overlooking the Rhône plain and facing the grand panorama of the Alpine peaks.

From its preparation in 2013 to its opening in 2016, and its continued development up to today (2026), the Mille Fleurs Botanical Trail has been a collective achievement led on a voluntary basis by its initiator, Marie-Jo Maillard from Dugny. This project came to life thanks to the financial support of the Municipality of Leytron, participatory donations, and the awarding of a prize. Its success is based on the close collaboration of several volunteers in the field, the municipality’s public works department, and all the people who contributed, directly or indirectly, to its creation.

Recognised and appreciated for the exceptional beauty of its route, the trail received the “Coup de Cœur” award from Sentiers-Découverte in 2017, highlighting some of the most beautiful itineraries in Valais. Winner of the 2018 Encouragement Prize awarded by La Poste in partnership with Suisse Rando, the Mille Fleurs Botanical Trail received support of CHF 10,000. This distinction remains rare, as only six trails in Valais have received it to date (2026).
