With 39 tunnels, 55 bridges and a difference in altitude of 1123 metres, the Albula line of the Rhaetian Railway between Thusis and St. Moritz is a masterpiece of railway engineering. It was opened in 1903 after having been under construction for 5 years. The section between Preda and Bergün is one of the most spectacular stretches in the world and is a prime example of how the high alpine landscape was opened up.
Parc Adula, a candidate for National Park certification, lies in the center of the Alpine arc. It is one of Switzerland’s largest contiguous landscapes untouched by significant human encroachment. The park’s eponym is the Adula Mountain, also known as Rheinwaldhorn, in the heart of the park.
The route to the Thal Nature Park leads through the compact township of Klus in the Balsthal. But an expansive, wondrous world of nature unfolds beyond this: the gentle rolling hills of the Jura.
