Tiirismaa

Tiirismaa is a hill formation in Hollola with hiking trails winding through quartzite rock formations and thick forest. The area features distinct geological characteristics, including the prominent Pirunpesä gorge and wetland zones along its edges.

The geological structure formed from ancient coastal waters that transformed into quartzite stone over a billion years ago. This extreme age makes the rock formations a direct window into Earth's early history.

The Pirunpesä gorge carries old local tales in its name, which means Devil's Nest, and these stories still influence how people experience the place today. Walking through the narrow rocky passage, visitors feel connected to the folklore that has shaped the area's identity.

The area is accessible via marked hiking trails that pass through forest and rock formations with regular rest areas along the way. Visitors should wear appropriate footwear since the terrain is uneven and can be slippery in places.

Along the southern edges lies the protected Soisalmensuo swamp, home to rare plant species that flourish in the specific conditions of this wetland. This protected area reveals a different character of the hill beyond the typical hiking experience.
