During paddling along the Swedish coast one is passing some nuclear plants. At some there is an advantage not to paddle through the area for outlet of cooling water, as flat water suddenly could become hard to manage. Forsmark is a typical place. It comes natural on the way north to pass Grisselgrund and continue NNV passing Tallhällen before choosing a more westerly course. One is then passing the area where the cooling water is let out. A better passage has been marked in this small map and in the picture to the right you will see the image of the bridge under which it is possible to pass.
