Prokopské jezírko

Prokopské jezírko (Prokopské Lake) is a small, striking lake in Prague, tucked into the Prokopské údolí nature reserve in the Hlubočepy district of Prague 5. Once a working limestone quarry, it's now one of the most photographed spots in the reserve.

How did the lake form?

Prokopské jezírko was created in 1905, when a disused quarry that had produced reddish-grey Třebotov limestone flooded. Local legend holds that a blasting operation broke through an underground water source, and the quarry filled up remarkably quickly. Whatever the exact truth behind the story, the result is unmistakable: what used to be an open-pit quarry is now a still, rock-ringed pool.

What does the lake look like?

The lake measures roughly 107 meters in length and 26 meters in width. On three sides it's enclosed by near-vertical rock walls left over from quarrying, giving the spot a canyon-like, almost alpine feel despite sitting inside city limits. The only easy approach to the water is from the western shore. The water itself is clear, which combined with the rocky backdrop is part of why the lake draws so many visitors and photographers. It's also known locally under two other names, Rusalčino jezírko and Hlubočepské jezírko.

Is it linked to a famous film?

Yes. The lake gained extra recognition through the cult Czech film Pelíšky, one of whose memorable scenes was shot right here. For many Czechs, the film is the first association that comes to mind with this name.

How do you get there?

The lake sits within the Prokopské údolí nature reserve in southwest Prague. The most convenient way in is on foot or by bike, following the trails that run through the valley. Hlubočepy train station makes a good starting point, from which paths lead into the reserve and on to the lake itself. No special fitness is required, though sturdy shoes are worth wearing given the rocky ground around the water.
