The famous Toblerone concrete blocks are lined up next to each other over a distance of some 10km from Lake Geneva to the Jura slopes. The route starts in Nyon and leads first to the Swiss National Museum in Prangins Castle. It then continues to the "Golf Club du Domaine Impérial" where the first fortifications can be seen near the lake.
Later on, the route passes the "Villa Rose", a small disused fortress that was disguised as a villa with painted-on curtains – now, it is a small museum with rooms that can also be hired for events.
The route follows the defence line to and beyond Bassins. As well as the tank traps, there are other fortifications and secondary buildings. A walk here gives some idea of the scope of the installations erected in World War II, and an understanding of the strategic considerations behind the layout of the structures on the terrain. As well as enjoying the small nature conservation areas, walkers should also take note of the plants that have now become established on the concrete tank traps.
From Bassins, there is an optional climb for athletic hikers to the viewing pulpit in the Bois au Ministre; the Toblerone tank traps, still preserved today, extended up into the Jura as far as this point.
