From here on, the route to Borowice (path to the west) has been re-marked BLACK, not yellow. (There are some yellow marks left over on stones though.) A yellow-marked route follows along the blue one towards Karpacz (north-east). I don’t know how far the new black marking goes beyond Borowice, so I better don’t edit the route relations in order not to do any damage. From here to Borowice I have walked the previously yellow route, and it’s definitely black now. The black marks end here, so a new relation will be required.
