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 BAM 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.
