Prokop Valley is a recreational area in southwestern Prague, located in the districts of Barrandov, Holyně, Řeporyje, Stodůlky and Hlubočepy. It encompasses two streams, Dalejský potok and Prokopský potok, the latter of which is surrounded by a valley, despite the fact that it is much shorter. The area includes a natural reserve which encompasses a far wider area than the valley.
