This is a weir on the Svratka river, a great local spot to cool down and relax on a warm day.
If you're looking for a simple, no-frills place to swim, this is it. You can take a dip in the river, and if you're feeling energetic, you can even try swimming against the current. After your swim, you can chill out on the grassy beach area.
One of the best parts is the pub conveniently located right next to the spot, perfect for grabbing a refreshing drink or a bite to eat.
The place is also registered as a bus station, so it should be easy to get to using public transport.
