Many people have seen tjønni down on Humlenesfjellet by Spåsomsnuten, when standing on top of Gøysen and heading down towards Flatsjå. This is a great area for camping or exploring Spådomsnuten, which is close by. You have to go up to the front of Gøysen. Masivet in front of Skorvetoppen. There are great animal trails and paths all the way up. If you're at the top, you can go down the hill, but you should go back to the first kink about 3-400 meters below. Then it's much easier.
