Directly on the path, we pass through 2 big rocks. On the left, there is a small wooden area around the rock, with a table and benches. Really nice to enjoy the view on the lake. But don't forget to turn around: on the rock itself, is a gigantic rune. I almost missed it, as I was focused on the lake view.

It's a pretty far downhill road to get here meaning you need to get up again... ;)

I'm not sure if it was due to the high grass, but I didn't see much other than this sign post. Be extremely careful of Ticks in in the summer and long grass. I removed two crawling on my legs from the northern coastal approach!
