If you can only do one thing in Ojców National Park, visit this 14th-century castle, one of the best-preserved castles in the upland. The castle was rebuilt in the 16th century in imitation of the royal residence of Wawel and now serves as a branch of the Royal Wawel Castle museum, with a large collection of art and artefacts from the 15th to19th centuries. The castle is near the northern end of the park, about 8km north of Ojców village.
From the castle, the red trail along the road toward Ojców takes you to a 25m-tall limestone pillar; it’s called Hercules’ Club (Maczuga Herkulesa), despite obvious temptations to name it after something else.
