While you are in the region you shouldn't miss the opportunity to visit one of the bat caves - and we're not talking about the kind inhabited by groovy heroes dressed in tights. Located either in or around the Ojców National Park, which is 35km from Kraków, there are over 400 caves providing habitat to at least 15 species of bat. The park itself is a collection of deep, steep-sided ravines and interesting rock formations shaped by the effect of underground water on the soluble limescale, which in addition to bat-spotting offer plenty of leisure opportunities, such as hiking and rock-climbing. A fascinating outdoor day trip, we list the most noteworthy caves in the region below.
