The city of Kielce, with its four geological reserves located within city limits, is an outstanding example of geological variety. The most famous is the Kadzielnia reserve in the unused quarry. Fossilised coral and cephalopods, a unique armoured fish, and brachiopods were discovered there.

You can also see interesting examples of various tectonic, mineral and karstic specimens in 26 caves. This remarkable place also has an amphitheatre carved in a rock face.

The Ślichowice geological reserve, which was established in the former quarry and is an interesting example of Hercynian tectonic influence exerted on the Świętokrzyskie Mountains, visible in the form of simple and strongly undulating lime rocks. You can see there an interesting geological profile with its reversed rock fold.

In the Wietrznia reserve, on the eastern edge of the Kadzielniańskie range, you can see upper Devonian limestone with banks of variable thickness containing fossilised remains of brachiopods, corals, snails, bivalves, trylobites, lilies and the armoured fish.

Biesak-Białogon, a reserve surrounded by forest being the smallest of the Kielce reserves, is also worth exploring due to its protected Ordovician and Cambrian outcrops showing a great deal of interesting tectonic features.
