Údolí Hasiny u Lipence, Educational trail and natural monument in Lipenec, Czech Republic

Údolí Hasiny u Lipence is a protected valley with diverse plant species and sedimentary rock formations spanning approximately 16 hectares. The Hasina stream runs through this area and shapes the geological character of the landscape.

The educational trail through the Hasina valley was built between 1982 and 1989 by members of the Czech Union for Nature Conservation from Louny and handed over to the public in 1989. In October 1992 the Lipenec Environmental Education Centre began operating here. The trail is dedicated to the memory of the Louny geologist and teacher František Štván, one of the first specialist guides to lead young people through the valley; the earliest mentions of the site date to 1879, when Antonín Frič recorded it.

The place functions as an outdoor classroom where students and visitors explore rock formations and fossils from the Cretaceous period. People regularly come here to observe the local landscape and understand its geological story firsthand.

The path has ten stations with information about geology and local plant and animal life. The route is well-marked and guides you past different rock formations that you can explore from start to finish.

The trail honours František Štvánek, a Louny geologist and teacher who was among the first specialist guides to lead young people through the valley; professor Antonín Frič is documented here as early as 1879. The path was built by members of the Czech Union for Nature Conservation from Louny between 1982 and 1989.
