Aarneset Gardstun is a historic farmstead by Oppstrynsvatnet in Oppstryn, run by Espen Aarnes and Helene Maurset. The farm offers accommodation in several buildings and a sauna by the water.
The sauna sits by Oppstrynsvatnet with views towards the mountains and has room for eight people. There is no toilet or shower at the sauna, but a small changing area and clean water are available outdoors. Guests can bathe in Oppstrynsvatnet right next to it.
