Burt finds out how avalanches are predicted, and takes us for a safe ride on the Bernina Express -one of the world's 10 best train trips. We learn the secrets of yodeling, cross the most dangerous mountain pass in the Alps, walk through the untouched forests of the Swiss National Park and tour St. Moritz-the original Alpine winter resort. Burt also visits one of the area's finest restaurants and gets the recipes for their most famous dishes.
