Went for a 10km hike along the mountains at the back of Nathalie's house.

Looked up the route on the inter web when we were done. There is a section on Croatian hikes titled "Red Tape". I thought this alluded to needing permits. It in fact tells you about the presence of mines.

"Red tape" said this trail was fine.
This is one case where hindsight may have involved losing a body part, and not gaining 20/20 vision.
