The outcrop displays distinct horizontal layers of moraine clay, sand, and gravel deposited during the penultimate glacial period in Lithuania.
It is classified as a hydrographic and geological natural monument of state importance.
The name 'Pūčkoriai' originates from the former Pūčkoriai manor and cannon foundry that operated in the valley during the 16th century.
The slope is approximately 260 meters wide at its base.
Geologists study the exposure to reconstruct the climatic history and glacial shifts of the Baltic region.
It is part of the extensive Pavilniai Regional Park, which protects the unique erosional topography of the Vilnius area.
Pūčkorių atodanga is the highest and largest geological outcrop in Lithuania, reaching a height of 65 meters above the Vilnia River. It is a protected monument of nature located within the Pavilniai Regional Park. The site exposes sedimentary rock layers formed during the Medininkai glaciation period approximately 18,000 years ago. The exposure was carved by the erosive action of the Vilnia River cutting through the glacial mound. The trail provides an elevated vantage point overlooking the Vilnia River valley and the surrounding forest landscape. The slope remains geologically active, with natural erosion processes continuing to modify the face of the cliff.
The main wooden observation deck at the top, which offers a panoramic vista of the entire exposed cliff face and the valley below.
Wear sturdy walking shoes with good grip as the paths can become slippery after rain.
Bring binoculars to observe the geological strata in detail and local birdlife in the canopy below.
Follow the designated wooden observation decks to prevent further erosion of the unstable cliff face.
Do not attempt to climb or descend the face of the outcrop, as the soil is loose, dangerous, and restricted to preserve the monument.
Stay strictly on marked paths and observation platforms to protect the fragile, eroding soil surface.
