The goal destination in this park for me was the viewpoint, which is located 8km away and can be reached by following the red trail E10 and at the tourist hut "Vennäänmutka laavu" you have to follow the dashed trail uphill, where one of the top views awaits you during autumn.
Be careful though, it's very far from the car park and there is no other pub or civilization there, I didn't even have a signal. Moreover, already in September, the day is quite short in this part of Finland, so plan this trip with plenty of time. But it is worth it!
Here you can see the endless mesas of trees and the meander of the river that winds through the national park. Here I recommend you sit and enjoy a snack and take in the view. For me, this is still one of the most spectacular views I've seen.
