interlaken to venice?

Hi, Please guide me as I am travelling first time to Europe.I live in India and I am planning a trip to Paris-Switzerland-Venice in early week of May and thinking of using Rail as the means of transport.One of my friend suggested me to buy a 2 country Euro Rail pass for France-Switzerland (as I am going to stay for a week in total there) and buy a single ticket for Switzerland(interlaken) to Venice as I am going to stay in venice for 1 day only.Please let me know if this will be best for my trip or else suggest me some other alternatives.

1. Is it worth to buy 4 country EuroRail Pass covering France,Switzerland and Italy (Please keep in mind my days of stay in the countries)

2. Can I buy rail ticket from Interlaken to Venice at the station itself (no advance purchase) as I am currently looking at RailEurope website and on a particular date trains for 13:11 time is not available but is available on sbb.ch website though I cant buy it in INR.

3. If in case any good coach service available to travel from Interlaken to Venice

Hi karan6112,

1. A rail pass is worthwhile for countries where you travel a lot. With only a single trip Paris - Switzerland and Switzerland - Venice, for example, you do not need passes covering France and Italy. So you first need a detailed itinerary, including town to town transfers and day trips (feel free to post your plans here). Then choose your pass. This guide helps you choose if you are interested in getting the cheapest option. In most cases, a pass dedicated to Switzerland works better than a Eurail Pass. Please see here for all passes, and be sure to download the maps of passes you're interested in so that you can see what's included.

2. You can, but I do not recommend that. Most trains to neighboring countries require seat reservations, and may be fully booked if you buy that late. Just purchase a ticket online along with your rail pass. The same applies for France to Switzerland.

3. Trains are the best choice. There are no long distance bus lines in Switzerland.
