Myswitzerland describes a few activities in the Vevey area that caught my eye and I'd like to get your feedback if you have done them. Vevey is a 2-night stop at the front-end of my late May 12-day trip.
Activity the First is the "Train des Etoiles" or Train of the Stars which takes you by rail to the nearby Les Pleiades hilltop. It's supposed to have various astronomical activities, but more interesting to me is the downhill bike path that leads back to town. An easy bikeride would be a good way to start the trip and slay the jet lag.
Activity the Second is the Train des Vignes vineyard tour by rail, beginning in Vevey and ending at the Puidoux-Chexbres station. It's a half-day, hop-on-hop-off deal that lets you visit vineyards, do tastings, etc.
Are either of these worthwhile in your estimation?
