The sandstone kingdom on the German border: Bohemian Switzerland National Park is rock towers and forest gorges the Elbe carved over millions of years — its crown the Pravčická brána: Europe's largest natural sandstone arch, a 26-metre opening above the forests, the country's first natural icon (and Narnia's famous film gate). The classic day is a perfect loop from Hřensko village: a ninety-minute forest climb to the arch and the historic Falcon's Nest lodge beneath it — then the enchanted Kamenice gorge: rock-hung walkways to the Quiet Gorge where oared boats carry you between twenty-metre walls near-touching — the boatmen hereditary tellers of jokes. From Prague two hours (Děčín train then Hřensko bus or taxi, with organised tours plentiful) — the capital's most successful full natural escape: ten hours returning you a calmer person.

Oars between near-touching walls — boatmen as joke-tellers.
The 1881 lodge beneath the arch itself — the historic summit lunch.
Hřensko, 407 17 northern Czechia
Yes, on the early train: Prague–Děčín a direct hour and a quarter, then seasonal bus 434 to Hřensko (or a taxi cheaper than feared) — count the last return bus precisely, the day's only gamble. The hesitant are served by Prague's plentiful daily organised tours at fair all-in prices — independents win the freedom of pace.
With half a day take the gorge and its boats: shorter climb, lighter effort, a magic resembling nothing — the arch seen in photos and left for a return. With a full day no question: the loop takes both, smartest order the arch by morning (its light loveliest from the east), the gorge at noon for its cool.
