Czechia's outdoor landscape is anchored by Bohemian Switzerland National Park — a sandstone rock city in the north of Bohemia, where Pravčická brána (Europe's largest natural sandstone arch) rises above a forest of rock towers and canyon trails that make the Czech-Saxon Switzerland border one of the most unusual outdoor landscapes in central Europe. The Krkonoše (Giant Mountains) carry the largest subalpine meadow plateau in central Europe at around 1,600 metres, with marked trails through mountain grassland and a summer wildflower display that surprises visitors expecting Alpine scale. The Moravian Karst cave system in the east — the Macocha Abyss, 138 metres deep, accessible by boat along the underground Punkva River — is one of Europe's most visited show caves with good reason. The Bohemian Forest (Šumava) carries wolf, lynx, and old-growth forest on the German border. The best part is often the hidden gems you were not even looking for. Take it all in.
