The Skałki Piekło pod Niekłaniem Nature Reserve is a protected area located in the Stąporków municipality, within Końskie County, in the northern part of the Świętokrzyskie Voivodeship, near the village of Niekłań Wielki. Established in 1959, it covers an area of 6.18 hectares and is one of the significant sites within the Konecko-Łopuszański Protected Landscape Area. The reserve is characterized by unique rock formations shaped by aeolian erosion, and it also protects the northern spleenwort (Asplenium septentrionale), which grows in rock crevices. The rock formations stretch for about 1 kilometer, reaching heights of up to 8 meters. The reserve serves as the starting point of a hiking trail leading to Wólka Plebańska and is part of the blue trail connecting Skarżysko-Kamienna with Kuźniaki, as well as the Piekielny Szlak (Hell Trail). This area attracts nature lovers and tourists, offering scenic views and unique rock formations, making it an interesting destination for both visitors and nature researchers. It is worth noting that the reserve is under partial protection, which helps preserve its natural values and biodiversity.
