This walk features varying landscapes: fields and forests along the valley of the river Aubonne, the vast park areas of the National Arboretum, as well as the vineyards above Lake Geneva.
Catch a MBC train from Morges to Bière across vineyards and the country-side to the Jura foothils. Starting out from Bière station, descend down to the valley of the river Aubonne, where a pleasant trail along the river takes you to the 130 ha site of the National Arbo-retum of the Aubonne river valley.
This huge park unique to Switzerland presents 3,000 tree and bush species and varieties from all continents. On the bridge crossing (after the lake), a small 10-minute detour lets you discover a coalman's heap, the Wood Museum, Arb'Espace and a refreshment stall.
On your return to the bridge, leave the Arboretum in the direction of Saint-Livres. Coming out of the forest you will enjoy a splendid view of Aubonne and its famous white tower. From Saint-Livres to Yens, a path above Lake Geneva will lead you along fields and vineyards.
Numerous benches and picnic areas are available along the way, such as at the Arboretum for example. Once you have finished your walk in Yens, you can take the MBC train back to Bière or to Morges.
