Divoká Šárka is proper wilderness just 20 minutes from city center. Take tram 20 or 26 to Divoká Šárka stop. Red trail through limestone cliffs and meadows is 3km, takes 1-2 hours depending on photo stops.

Natural swimming pool at Šárecký potok gets busy summers, plus several marked trails from easy walks to moderate climbs. Pack water and wear real hiking shoes - this isn't city park territory.

Early morning before 8am you'll have trails mostly to yourself. Limestone formations are incredible and wildlife surprisingly abundant this close to Prague.
