I will be in the Montreux/Lausanne area during the first week of October and will have a free day or two to do some hiking. I am looking for something that I can do in a day trip from the Montreux area that will have great alpine scenery (i.e. - high mountains, lakes, streams, etc). I would love to hear your suggestions on what the must do hikes are in that area. I do not mind strenuous hikes and I am willing to travel by train a bit, as long as I can do it in a one day outing. Thanks for the help!
