Relatively flat basalt hill above the village Hlinná.
There is a nature reserve of the same name with the occurrence of rare plants, especially plant communities with Pulsatilla pratensis and Pulsatilla patens. Pulsatilla hackeli also grows here, which is a natural hybrid derived from the two previous species. On the west side of the hill, there are variously scattered basalt rocks called the Teacher and Pupils.
