Bohnické údolí, Natural monument in Bohnice, Prague, Czech Republic

Bohnické údolí is a valley in Prague-Bohnice whose natural section is protected as a natural monument. Bohnický potok flows along its axis toward the Vltava, and the Bohnická street with a city bus line runs through it. The protection covers the south-facing rocky slopes above the stream, where pre-Paleozoic slate outcrops support rock-steppe plant communities.

The valley was formerly called Lísek, after an estate whose vineyard remains are still visible on its slopes. It was later used as pasture and as vineyards, and its present form results from erosion by the Vltava and its tributaries. The natural monument is administered by the Prague City Hall and protects south-facing rocky slopes above the Bohnický stream.

The valley was formerly called Lísek, and remnants of the Lísek estate vineyards remain visible on its slopes. The protected steppe rock communities survive only through regular maintenance; without it, blackthorn and dogwood thickets would overgrow them.

Several walking trails wind through the protected area with informational signs about local wildlife and plant species. The valley is easily accessible by public transportation from Prague.

The valley was formerly called Lísek, and remnants of the vineyards of the Lísek estate are still visible on its slopes. The protected area is home to the critically rare Czech tulip Gagea bohemica, along with Dictamnus albus and Rosa gallica.
