Les Avants is half an hours train journey from Montreux. It is high up in the hills but worth it for the magnificent views above Lake Geneva and Montreux. Trains are frequent so travelling to and from Montreux is easy. Les Avants is a tiny village in the hills with only a couple of restaurants but lovely scenery. It is a nice contrast to the town of Montreux which offers more things to see and do. I recommend this place highly.
