Take Villeneuve’s highway exit, keep going in the direction of Villeneuve for about 1 kilometer and you will arrive to the camping’s parking (on your left). The harbor itself is very close from this parking. If you are arriving from Montreux using the by-road, the parking will be on your right after crossing Villeneuve.
Exit the train at Villeneuve, cross the road and walk along the lake towards Villeneuve's port.
