The hut at Katnosdammen was once the dam keeper's house, but today it is owned by the Norwegian Trekking Association (DNT) and is therefore open to everyone. However, it must be booked in advance. The cabin is beautifully situated right by the lake and is very charming both inside and out. Canoes and life jackets can be provided for overnight guests. You can find more information and the link to book the cabin here: https://ut.no/hytte/10778/katnosdammen.

Great location for a break when on a hike or gravel ride. Benches around and a nice view by the lake.

Nice spot for one tent or a couple of hammocks. Easy road access, but it will be shadded in the setting summer sun.
