Take the E22 road towards Gladhammar. Once you reach your destination, you will find a dead end. However, there is a gravel path that continues through the forest, passing by some houses. This path eventually leads to a designated area for forest work. Note that there are no amenities available here. Nevertheless, it can be a pleasant hiking route.
I visited the place and stayed there for a night. It is a remote location with a lot of space. However, it is not located directly by the water, and as far as I know, there is no direct path to it. Overall, still highly recommended. Having a vehicle suitable for rough terrain is likely advantageous.
