Zadni Kościelec (2162 m a.s.l.) is a compact, rocky peak in the lateral Kościelec Ridge of the High Tatras — a place where solid granite, dramatic views and genuine alpine character come together. It is a favourite among climbing course participants and beginning alpinists, which has earned the whole ridge the affectionate nickname 'Ridge of the Forefathers'.

The peak sits between Mylna Pass (2106 m) and Kościelec Pass (2110 m). Its western face drops in a sheer wall into the Green Gąsienica Valley (Dolina Zielona Gąsienicowa), hosting some of the most popular rock-climbing routes in the Polish Tatras. The eastern side features a rocky spur called Kościelcowa Grzęda, separating the cirques of Czarny Staw Gąsienicowy and Zmarzły Staw. In summer the ridge is lively with climbers; in winter it becomes a serious undertaking requiring winter mountaineering skills.

• Zakopane / Kuźnice — approach via the Jaworzynka Valley or the Green Gąsienica Valley to Mylna Pass area, then along the ridge to the summit; difficulty: demanding (alpine terrain, basic climbing ability or guided course required).

• Zadni Kościelec is alpine terrain, not a marked hiking trail — basic climbing skills are required.
• The western wall is one of the most popular climbing areas in the Polish Tatras; route no. 100 in W. H. Paryski's climbing guide, known as the 'setka', is especially popular with courses.
• A small cave called Schron w Zadnim Kościelcu is located near the summit.
• The area lies within Tatra National Park — an entry fee is required.

The first summer ascent was made by Zygmunt Klemensiewicz and Roman Kordys on 5 August 1905 — a piece of Tatra history etched into every pitch of this beautiful ridge.
