If you are new to the area and would like to discover more about the local wines, or if you know the wines already and want a fun day out, the two “Caves Ouvertes” days on Saturday 23rd and Sunday 24th of May between 10:00 and 18:00 are an ideal opportunity to taste and drink local wine. To take part, just purchase a “passport” at the information desk at Rolle, Gland or Morges railway station or at the first winery you visit. For just CHF 15 you receive a souvenir wine glass, wine tasting from a wide choice of wine cellars and a free ride that operate between the cellars and Morges railway station. There is a full timetable of the free buses here. See the routing here
Also, on this Sunday it’s the fabulous Navale parade in Rolle, this is when all the CGN “Belle Epoque” boats gather together and parade on the lake, ending in a grand choreography to music and the release of thousands of balloons into the air from the boats. For full details see site here
