Geopark Rudice

Geopark Rudice is an open-air geological exhibition set right next to a historic windmill in the village of Rudice, deep in the Moravian Karst. It's free to visit year-round with no opening hours to plan around, which makes it an easy stop for anyone already walking through the village.

What exactly is on display?

The route runs along a path lined with flat stones, next to which stand rock specimens gathered from across the Moravian Karst and the neighbouring Drahany Highlands. Several of the exhibits weigh multiple tonnes, and each carries an information plaque naming the rock type and where it came from. Walking the geopark feels a bit like flipping through a regional geology textbook laid out outdoors — no ticket, no guide required, though a guide would help catch details the plaques leave out.

What's inside the windmill next door?

Right beside the geopark stands a windmill built in 1865, a Dutch-type mill with a circular stone wall 135 cm thick at the base and 7.5 metres tall — the only structure of its kind in the area. Since 1994 it has housed a museum with permanent exhibits on the history of windmills, local village life, historical ironworking, and speleology. Since August 2014, the display has also included a 3D projection that shows the underground cave system of Rudické propadání in spatial detail.

The collection's centrepiece is a set of unique Rudice geodes — quartz nodules filled with colourful crystal formations — largely gathered by local collector Alfons Matuška. It's this collection, more than anything else, that draws mineral enthusiasts to Rudice from across the country.

Why does Rudice matter so much to cavers?

The village sits above Rudické propadání, the most powerful collapse sinkhole in the entire Moravian Karst, protected as a national natural monument since 1992 and covering 4.4 hectares. Here the waters of the Jedovnický stream drop 90 metres, forming one of the highest waterfalls in the Czech Republic. Connected to the Býčí skála cave, the system stretches over 13 kilometres, making it the second-longest cave network in the country. It also contains Rudická propast, the deepest dry karst shaft in Czechia, and Obří dóm, one of the largest cave chambers in the country.

The cave chamber right at the sinkhole is freely accessible via a footbridge over the stream, but reaching the collapse itself is far more demanding and requires experience. A full traverse of the underground system is only organised by local cavers as part of speleology courses, and the trip underground typically takes around five hours.

What else is worth seeing nearby?

Two educational trails start near Rudice — one to the Jedovnické Ponds, the other to Rudické propadání and the nearby kaolin quarries at Seč. Both make a natural extension for visitors who have more than just a quick stop at the windmill in mind.

Frequently asked questions

Is Geopark Rudice free to visit? Yes, it's an open-air exhibition, accessible year-round at no charge.

Does the windmill museum charge admission? The museum inside the windmill operates separately from the outdoor geopark, with its own pricing and opening hours.

Can I explore Rudické propadání on my own? The cave chamber by the collapse is reachable via a footbridge, but a full traverse of the system requires joining an organised speleology course with local cavers.

How long does a visit to the geopark take? The route itself takes only a few minutes to walk, though it's worth slowing down to read the plaques next to each specimen.
