RE: Welcome to Verkeån Agusa-Hallamölla Nature Reserve!

This place seems oddly nostalgic to me, like a happy childhood memory of a perfect summer day hiking in the forest. It is such a great feeling walking down a new trail, not sure what lies around the bend, sun shining, birds chirping, and the sounds of a waterfall up ahead. I wonder, was there any explanation for the small cave and its purpose?
