The deep gorges of Helvetinjärvi National Park were formed millions of years ago by faults in the bedrock running right through the area. Today this rugged scenery attracts hikers for both day trips and camping. From the Park it is possible to walk all the way to Riuttaskorpi recreational forest and Seitseminen National Park on hiking routes called Pirkan Taival.
Helvetinjärvi National Park is representative of the variable, wild forest landscape of the northern part of the former Province of Häme. Special features of the area include deep rifts, steeply sided lakes, small forest ponds and remote forests. Helvetinkolu, one of the gorges, has attracted visitors since 1800s, and it is still the most popular destination in the Park.
