The road number 12 (long one in the middle of the forest) is what you are looking for. Then look for Old part of the forest with tall pines and fern on land (on your left heading North). Intersection of road 24/25 is probably best spot. I wouldn't recommend going there if you are lacking imagination...

They do forestry here! If part of Lord of the Rings was filmed here then now you can't see any of it anymore

It took a little while to find the place I was beginning to despair and then finally on the road 12 in the forest, it became obvious, a scene from the lords of the rings has been filmed there. Of course there is not a specific point but the atmosphere is there. The place is a must if you are also a fan as I am of the lords of the rings I recommend it! it's 2 hours of walking and free!
