An alpine adventure for PostBus enthusiasts across two passes and through three holiday destinations in the Grisons region. When it comes to variety, the trip from Chur to Zernez via Lenzerheide and Davos is hard to beat.

The PostBus meanders through the villages of Malix, Churwalden and Parpan up to the Lenzerheide high valley. After passing the summit in Valbella, the PostBus continues along the shimmering Heidsee lake and through picturesque villages to the Landwasser Valley and to Davos. Davos has a wide variety of activities in store for you - on the lake and in the mountains, or you could visit the Kirchner Museum.

The second part of this delightful trip takes you from Davos across the Flüela Pass (2383 m). Now since the Vereina Tunnel has been completed, the Flüela Pass is open only in the summer. The mountain panorama on the last section on the way down to Susch and Zernez in the Engadine will take your breath away.
