The largest and most visited tajch (a historic mining reservoir) in the area lies beneath Sitno (1,009 m above sea level), the highest peak in the Štiavnica Mountains.
You can hire pedal boats, rowing boats and paddleboards, with life jackets provided. In the evenings a pig is roasted on the spit and live music plays at the ‘Terasa u Blaškov’ on the shore. If you’re also planning to climb Sitno, make a full day of it.
