Montreux is a major resort town on the shore of the Lake Geneva, so it's not difficult to get here, but still there are still no direct flights from the CIS countries, so you have to make a transplant. It is easiest to fly to Geneva (airfare on one adult in both directions will cost approximately $ 350, depending on the airline), then in Geneva it is worth transferring the train, unfortunately there is no direct train from Geneva to Montre, so it will be necessary to transplant in Lausanne. Arriving at the airport, the most important thing in Geneva to go to Switzerland, and not to France :). In Geneva, there are two stations - central Kannabins, which is located not far from the city center, and Kuentren Station is almost at the airport.
From both stations, trains are sent to Lausanne, so it makes no sense to go to the central station. With Cuentren Train to Lausanne, literally every half hour and moving to Montrere with a change in Lausanne will take just a little more than an hour. Ticket price per person 17 trings. More precisely, the train schedule can be viewed on the official website of the Switzerland railway http://www.sbb.ch/en/home.html
In Montreux, the station is located literally at the promenade itself, so it will not be difficult to navigate there.
This is how the station looks like in Lausanne, it will not be worn there is practically impossible.
As an option, if the main goal is a trip, in Europe you can go on a car (Ticky this is a mercenary costly Pleasure gasoline and paid roads just worth it) and the car will have to be almost a day, because a distance of more than 2,000 kilometers, although species and places that can Visit along the way. It will be more convenient and faster to go through Poland Czech Republic Austria and Germany.
