Pirunpesä Gorge and Tiirismaa hill

The monumental Pirunpesä Gorge is a cliff fissure cutting through the quartzite rocks of Tiirismaa and has been a well-known visitor attraction since the 1800s. The walls of this impressive rock formation are up to 20 metres tall. Pirunpesä, which translates literally as Devil’s Nest, is one of the most important geosites of the Salpausselkä UNESCO Global Geopark. A marked hiking trail of 4,5 km passes by Pirunpesä. The trail can be reached from the parking area at road “Arvi Hauvosen tie”.
You can also reach Pirunpesä from Lahti Sport Centre through Salpausselkä gravel routes.

Tiirismaa cliff area is nationally recognised for its value in terms of nature and landscape conservation. The originally high mountain has been eroded in the course of time, but is still the highest point of southern Finland, 223 m.
