Swiss Tectonic Arena Sardona.

The Swiss Tectonic Arena Sardona is a UNESCO World Heritage site in northeastern Switzerland, covering 32,850 hectares of striking geological landscape. Renowned for its exceptional Glarus Overthrust, this arena showcases a dramatic interplay of ancient tectonic forces where 250-million-year-old Verrucano rock is thrust over younger Flysch rock formations. Since the 18th century, it has been a vital site for geological research. Visitors can explore the stunning Glarus Alps, featuring six peaks over 3,000 meters, and the area’s remarkable natural beauty, including glaciated mountains and valleys. With well-marked hiking trails like the Sardona World Heritage Trail, the arena offers an immersive experience into Earth's geological history and ongoing dynamic processes.
