So this summer we went north, behind enemy lines, to take it all back. But distracted by all our delicious Danish pastries and snacks (okay, maybe it was Kvikk Lunsj), we forgot to follow the red markings on our trail. We can still see our cabin but have no clue how to get there - can you help us find our way?

The flag is the cabin’s Google Plus Code when clicked on in Google Maps (without city and country), wrapped in brunner{}.
