We were there yesterday (13-8-22), but left again. There was a (new) sign (on a tree along the access road) which indicated that you were not allowed to camp/spend the night there. Turned off the light in the toilet...

It is indeed a museum with old crafts and where you can look around yourself. Now in June there is no one who comes to swim in the cold water, so we put the camper in front of the canteen. Indeed many mosquitoes so bring mosquito spray.

Beautiful place to visit during the day, but is certainly not an overnight location.
