Pravčická brána, the largest stone arch in Europe, from Hřensko

The symbol of Bohemian Switzerland: a sandstone arch with a span of 26.5 metres, the largest natural stone arch in continental Europe, which in 2004 served as the setting for The Chronicles of Narnia: The Lion, the Witch and the Wardrobe, the first film in the series. Next to it, Prince Edmund Clary-Aldringen built a wooden chateau in 1881, the Sokolí hnízdo (the Falcon's Nest), which is still a restaurant. You can no longer climb on top of the arch, which has become fragile; it is viewed from the terraces and viewpoints of the site.

You can reach it only on foot. You set out from Hřensko along the red waymark or, more comfortably, from the Tři prameny bus stop, about 3 km from the arch: a wide path that climbs through the forest, with stairs at the end. Allow an hour's climb and a little less for the descent. The site is paid (125 CZK) and open every day from March to October; from November to March, only Friday to Sunday and with limited services. Bring water and mountain footwear: in summer it is hot on the climb.

In 2022 a fire burned hundreds of hectares around; the arch was unharmed, but you will see the burned forest and how it is regrowing.
