The Kynžvartský kámen Nature Monument (Kynžvart Rock) is a 5-metre high dome-shaped block with round sides furrowed with marked grooves (up to 0.5 m deep and 5-20 cm wide), caused by mechanical and chemical aggressiveness of down-flowing precipitation water. Similarly to a number of other formations in its close surroundings, (e.g. four prominent round blocks standing by a marked path), the rock block is probably the product of subsurface weathering and it represents the more resistant rock "core", which surfaced following the erosion of overlaying waste.
The Kynžvart Rock stands by the yellow-marked tourist path leading from the railway station in the spa of Lázně Kynžvart via a field path to the town of Kynžvart. The path is suitable for cross-country or mountain bikes only. The first half leads through woods where several granite rocks are scattered. One of these rocks has a particularly imposing appearance. It has been subject to protection since 1997 because pseudo-karren (Czech: pseudoškrapy) evolved as a result of gradual weathering. The term "škrap" (karren) is of Serbian-Croatian origin and it denotes grooved cavities on bare limestone surface as seen in the Dinar Karst. Similar cavities were created on the Kynžvart granite rock and because they resemble karren on karst rock, they are denoted as pseudo-karren. Pseudo-karren and are formed by a combination of downward flowing water, mechanical erosion, and chemical weathering. You can reach the rock if you turn right at an information sign behind Luční rybník (Meadow Pond) and continue on the path for another 250 metres.
The field path then continues through a wood to a field where, at the edge of the wood on the right, you can observe another group of granite rocks. You may see an interesting object on top of one of them resembling a rock bowl. It was believed that the bowl had been made by man and that it had served for pagan rituals as a sacrifice bowl. However, its natural origin has been proven and it is formed in a similar way as karren. Another rock bowl may be found on the perched boulder known as Dominik. The largest rock bowl may be found near Slavonice close to the town of Jindřichův Hradec. It is almost 3 metres long and 1.2 metres deep.
