The waterfall is technically a cascade resulting from the modification of the Olszanka riverbed during the construction of a historic mill.
It is situated within the Uherce Mineralne village area, known for its specific microclimate and mineral water history.
The rock layers visible at the site are part of the Krosno formation, characterized by alternating beds of sandstone and shale.
Despite its modest height, it is considered one of the most picturesque hydrological points in the immediate vicinity of Lesko.
The Olszanka River Waterfall is a natural geological feature located in Uherce Mineralne within the Bieszczady foothills of southeastern Poland. It is a man-made cascade remnant formed by stone blocks, historically associated with the operation of a former water mill. The site serves as a local point of interest for visitors exploring the San valley region. The water flows over a series of rock ledges creating a tiered effect. Surrounding the site is a forested riparian landscape typical of the Podkarpackie region. The waterfall is accessible via a short walking trail leading from the village infrastructure. Its geological composition features flysch rock formations common to the Outer Western Carpathians.
The elevated bank directly opposite the central cascade provides the most comprehensive view of the tiered structure.
Wear waterproof hiking boots as the riverbank and surrounding soil can become muddy.
Bring insect repellent, as the damp environment near the river attracts mosquitoes during the warmer months.
Visit after a period of rainfall to see the waterfall at its most active flow.
Do not attempt to swim in the pool below the waterfall, as the water can be unpredictable and debris may be present.
Stay on marked trails to protect the fragile bank vegetation; do not litter in the river ecosystem.
