Blatenský Hill, with its stone lookout tower, hides the “Wolf Pits” on its slopes—deep rock cavities formed by the collapse of the ceilings of medieval mines, where snow and ice remain year-round in the “Ice Pit.” Bike Trail No. 23 runs less than a kilometer below the summit, and to reach the lookout tower, you’ll need to take a short detour up a steep hill. Since cycling directly into the protected sinkholes is strictly prohibited, lock your bikes at the top near the lookout tower on Blatenský Hill, where you’ll find refreshments and bike racks, and walk down about 250 meters to the pits.
