Ostrężnik Nature Reserve in the Kraków-Częstochowa Upland

In a forest between Złoty Potok and Żarki hides one of the smallest reserves of the Jura: Ostrężnik covers only 4.1 ha, was created in 1960, and still holds a fragment of beech forest, a 14th-century stronghold and karst curiosities. The whole area lies within the Natura 2000 site „Ostoja Złotopotocka” and the Eagles' Nests Landscape Park.

The Springs of Events

At the foot of the hill flows a periodic karst spring called the Sources of Events. It appears and disappears regardless of the season — it may stay dry for years, only to gush forth with great force another time. People once believed it heralded important events, hence the name. This is a typical phenomenon of limestone terrain, yet one of the most spectacular in the region.

Castle, cave and legend

On the summit barely readable walls remain of a 14th-century castle, whose construction is attributed to the initiative of Władysław Opolczyk, although the stronghold may have a different origin. At the foot of the rock lies Ostrężnicka Cave, 90 m long — it once served as the natural cellars of the castle, and during the Second World War partisans hid here. According to legend, January Uprising insurgents hid documents and treasures here after their defeat in 1863.

Trails and practicalities

The red Eagles' Nests Trail and the blue Trail of the Jura Strongholds run through the reserve, and the „Tropem tajemnic” educational path (1.5 km) makes access easy. Entry is free, and after your walk Złoty Potok and the Parkowe reserve are close by.
