One of the most cost effective ways to travel in Switzerland is by rail. Swiss trains are almost always on time, very clean and best of all you can catch any train you want to get to your destination. The Swiss Pass: take the most spectacular rail trips in the World is one of the best ways to get around.
Possibly you are interested in the Golden Pass Tour. Maybe I enjoy this tour because it goes through the beautiful area of Montreux. OR the fact that is covers the most beautiful areas in Switzerland within 6 days, hotel included.
Check out some of the scenic routes which save you $$$$. One of my favorites is the chocolate train which gives you a first class tour of the Gruyere cheese tasting and the Calier Chocolate factory of Nestle. At $22, how can you go wrong, and that includes tour admissions.
