I would like to attend the Yodel Festival in Tremelan, Switzerland, June 14-16 2013. I can not find a route, train, bus. I am planning on buying a eurail pass.
If your going to the Bernese Yodel Festival in Tramelan, there is a connection out of Bern at 43 past the hour, every hour starting at 6:43.
Tramelan (note spelling) is easily reached from either Zurich or Bern. There are 3 train changes on the way, at Biel, Sonceboz, and Tavannes. Use the Swiss train website SBB.ch to see the schedule. Wish I could go-I love to hear yodeling. We were in Grindelwald once when a yodel club came and sat down at the outside tables at our hotel around 8 pm. They were served free drinks as long as they kept singing. The haunting sounds filled the streets all around. It was a real treat!
