In Lausanne we enjoy the great outdoor areas beside the lake, just between the Bellerive Swimming Pool and the Port of Vidy, close to Avenue de Rhodanie 31.
Simply take the Metro M2 from the train station downhill to Ouchy, then turn right towards Geneva. Walk for about 10 minutes, until you have passed the swimming pool, and turn left into the parking area. We meet right there.
