A wild wooded river valley on the edge of Prague that feels like a total escape from the city — locals bring their kids here to hike, wade in the stream, and burn off energy on warm days. Entry is completely free and the reserve is open year-round from dawn to dusk. The main trail along the valley floor is mostly flat and stroller-friendly, while side trails offer slightly more adventurous terrain for kids who want to scramble. A small outdoor seasonal swimming area (Divoka Sarka koupaliste) operates in summer with a pool, slides, and a snack stand — admission is roughly 100 CZK / $4.50 USD per person. Bring snacks and water as facilities are limited and wear closed shoes since the stream paths can be muddy.
