30-km Hiking Loop at the Southern End of Lake Herajärvi

Rocky trails and steep ascents and descents add a challenge to the hike. Crossing bodies of water via a towboat and a wading rope also adds a pleasant variety to the hike.
Along the way, you can explore old tar pits, charcoal kilns, and a kyanite mine. The pristine old-growth forests, with their streamside groves, add a wonderful touch to your scenic experience and immerse you in a world of delightful forest scents.
