The nature reserve "Bujakov vrch" is situated where the town of Nová Baňa meets Veľká Lehota, about halfway between Vojšín hill and the Sedlová Skala rock. The Vojšín Educational Trail will take you there. Extremely rare and protected pasque flower (Pulsatilla grandis) are commonplace across the 1.26 hectare area of this nature reserve. From March to early May, the site blooms with unmistakable pinkish-purple flowers. Pulsatilla grandis belongs to the group of protected species which rarely appear in Central Slovakia. As such, it cannot be torn or picked. The whole plant, especially its above-ground part, is poisonous. Its ingestion slows down the heart rate and can lead to coma.
