The mountain's rock formations are remnants of a sedimentary sea floor deposited during the Cretaceous period.
The first documented tourist visit to the summit was made by Prussian King Frederick William II in 1790.
The 'Piekiełko' chasm is known for its microclimate where snow and ice can persist into the early summer months due to poor sun exposure.
The mountain summit consists of a labyrinth of narrow corridors, some of which are only centimeters wide.
The stone staircase leading to the summit was commissioned by Franz Pabel, the first officially appointed mountain guide in the Sudetes.
Szczeliniec Wielki is the highest peak of the Table Mountains (Góry Stołowe) in the Central Sudetes, reaching 919 meters above sea level. It is a mesa-type mountain characterized by a labyrinth of weathered sandstone rock formations, crevices, and narrow passages. The summit area features a designated one-way tourist loop that winds through complex rock shapes, including 'Hell' (Piekiełko) and 'Purgatory' (Czyściec). Geologically, the mountain is a remnant of a larger sandstone plateau subjected to differential erosion. A historic mountain shelter, PTTK Schronisko na Szczelińcu, has operated near the summit since 1846. The summit plateau provides panoramic views of the Karkonosze range and the Broumovsko region in the Czech Republic. Access to the summit area requires climbing approximately 665 stone steps, mostly dating back to the late 18th century. It is located within the Table Mountains National Park (Park Narodowy Gór Stołowych).
The 'Fotel Pradziada' (Great-Grandfather's Armchair) rock formation, which offers a vantage point overlooking the surrounding mountain landscape.
Wear sturdy hiking boots with good grip, as the sandstone stairs can be slippery when wet.
Bring a light jacket even in summer, as the temperature drops significantly within the narrow rock corridors and tunnels.
Check local weather reports specifically for the mountain peak, as visibility and wind conditions often differ from the valley floor.
Attempting the climb during heavy rain or thunderstorms, as the stone steps become dangerous and the metallic railings provide no shelter.
The summit tourist loop is closed during the winter season due to safety conditions, typically from November through April.
Stay strictly on the marked path as the ecosystem is protected; do not climb on the sandstone rock formations outside the designated route.
