You can fish in Rolleivstad with a bought license.
Rolleivstad Lake is a very good fishing lake for trout; the last trout taken in 2015 was 1.3 kg! (2,9 pounds). It is a regulated lake, with regulations height on 2,5 meters (8,2 feet). The last fry was set loose in the lake in 2006 but since then we’ve upgraded the spawning river, in hopes that the lake can sustain itself with fish naturally as in old times.
Be attentive that the municipal fishing license you can buy in Fyresdal city center does not include Rolleivstad lake.
Other than fishing and hunting you can go mountain hiking and because of the “right to roam” in Norway you can pick whatever berries you happen upon.
