Coming on the highway from Geneva, take the exit Gland/Begnins, then direction Begnins (Jura). Before you come to the first roundabout, you have WARO (commercial centre) on the left side. Continue straight on direction Begnins and park after 500 m on the left side of the second roundabout. You are now in Vich and from this parking you can see the church and the post office.
