Route:
Landquart - Klosters - Zernez - St. Moritz

Start off in Landquart, climb the steep ascent to Klosters, pass through the Vereina tunnel, the world's longest meter-gauge tunnel, to Zernez and St. Moritz. Up here, activities are manifold: hike in the Swiss National Park, where you can view pristine flora and fauna up close, take a stroll around Lake St. Moritz, through the Staz Forest or climb up to the local mountain Corviglia or visit the local Segantini Museum, dedicated to the artist whose paintings capture the area so well.

St. Moritz offers plenty to do and the Engadine Star gives you six hours of time in case you want to take the train back the same day.

From Zernez, you can alternatively take a Postbus over the Ofen Pass to the Val Müstair (Engadine-Meran Route Express) and on to Mals (Italy). Here, take the new Vinschgauer railway to Mediterranean Meran (www.sad.it; Swiss Travel System tickets are not valid).
