In order to get to the Lavaux region, you can choose between car or train.
With a car it's easy, you just take the motorway from Lausanne towards Montreux- Villeneuve and you take the exit "Chexbres". Then you can drive around and park where you find a nice spot.
A tourist-train (Le LAVAUX EXPRESS) leaves from Lutry harbour, east of Lausanne, for a one-hour trip through the region. The schedule varies so you better check before you plan your trip.
Buying wine directly from the wine-grower means also buying wine only after tasting.
Many wine-growers have nicely decorated wine-cellars and welcome you after having made an appointment.
Favorite thing: See what happens with the fresh grapes and taste the fresh pressed grape juice. Strange taste to me!
