The 'szumy' are acoustic phenomena caused by the characteristic rustling sound of water flowing over the rocky ridges of the riverbed.
The reserve protects a specific geological fault line that separates two distinct tectonic units of the Earth's crust.
It is home to the protected European pond turtle, a species rarely spotted elsewhere in the region.
The trail incorporates the junction of two rivers, the Tanew and the Jeleń, where the waterfall density is highest.
The reserve is an important nesting ground for the black stork, a species sensitive to human disturbance.
Rezerwat przyrody Nad Tanwią is a forest nature reserve in southeastern Poland, famous for the 'szumy'—a series of 24 small, cascading waterfalls created by rocky thresholds on the Tanew and Jeleń rivers. The reserve spans approximately 41.27 hectares and serves as a vital transition zone between the Sandomierz Basin and the Lublin Upland. The primary attraction is a 10-kilometer walking loop known as the Szlak Szumów, which follows the riverbank through protected woodland. The area features diverse plant life, including rare species like the martagon lily and various orchids. Geologically, the waterfalls represent the fault line where the two geographical regions meet. The reserve is maintained by the State Forests and is part of the larger South Roztocze Landscape Park.

Bring waterproof footwear as the riverside paths can become muddy after rainfall.
Carry insect repellent, as the humid, forested river valley is a prime habitat for mosquitoes.
Start your hike early in the morning to avoid crowds, as this is a popular destination for school trips and weekend hikers.
Do not attempt to swim in the Tanew River; the currents near the waterfalls can be unpredictable and the water is shallow with hidden rocks.
Stay strictly on marked trails to protect the sensitive riverbank ecosystem; do not pick plants or disturb wildlife.
