Today, at over 30 degrees, from Altenau in the direction of Torfhaus. UNESCO World Natural Heritage Upper Harz Water Management. Very impressive. I was hoping for more shade...
Return via the Wolfswarte. Great view.

I was a bit afraid after seeing all that dead forest, that it wouldn't be fun to walk. Well, contrary to that thought, the first walk was really a party. Lovely weather, nice varied route and beautiful views.
