Have just returned from Lac Leman where I was checking out things to do and places to visit with lots of teenagers in the summer. Thanks to all your advice - especially yarpos - I saw some wonderful places. Our concert venues look brilliant - especially in Lausanne. One thing left to organise. I know that the students will want to get as close to "real mountains" as they can! Which is best from Evian les Bains? Chamonix, the train to Montenvers and the Mer de Glace or Les Diablerets. It would have to be achievable in one day, the only day that we don't have a concert in the evening.
Any help gratefully received.
