The best part, in my opinion, is the Geo Park. I’m a huge fan of nature trails in general, especially ones geared towards kids, because they combine learning with easy hiking, and this was very nicely done. Since this is Cesky Raj, the trail passes beautiful cliffs with unique features, like a honeycomb effect. The plaques teach about the local geology, for example by showing various crystal formations. At one point you make your own river, with sediment deposits, to learn how flow alters landscape, and another station has you working on a large-scale puzzle with pictures of local scenery. The final challenge is walking on the small platforms that form a path over a boggy-looking pond. Don’t fall in! Don’t worry, there’s a safer dirt path on the other side.
