Kališovo jezero, also known as Kališok, is a man-made lake created from a former gravel pit. It's a popular local spot for a refreshing dip, especially if you're looking to avoid the crowds of public swimming pools.
The biggest draw is the water itself—it's incredibly clear, with visibility reportedly up to 3 meters. [1] It's a peaceful place, frequented mostly by cyclists taking a quick break and locals. For recreation, you'll find a volleyball court, football goals, and a small playground for kids. The entry into the water is made easier with concrete panels and flat stones.
While generally peaceful, some visitors have noted that local fishermen aren't always the most welcoming. Also, the beach area can sometimes be a bit dirty. Keep in mind that facilities are minimal; there are no restaurants or bars right at the lake, so it's best to bring your own supplies.
