Pravčická brána, Bohemian Switzerland

The largest natural sandstone arch in Europe, 26 m wide and 16 m high, in the Bohemian Switzerland National Park, a landscape of rock towers, gorges and forest along the German border. You can't walk on the arch, but the viewing terraces nearby give a great view, and the Falcon's Nest chalet stands below it.

Walk up from Hřensko, about 1.5 hours. Combine it with a boat ride through the Edmund Gorge (Soutěsky Kamenice). The German side, Saxon Switzerland, has the Bastei bridge. Some trails close after the 2022 forest fire; check before you go.
