Rules on public and private ground
Generally, you are free to go anytime and anywhere on foot, when you are on public ground. You can go outside the paths, tracks and roads 24 hours a day. However, there can be limited access in hunting season. You can set up camp in several forests (this means that for the most part it is not allowed). You can find the forests here and read more camping in nature.
On private ground you can only walk on existent paths, tracks, trails, and roads from 6 am until sunset, and you have to respect the places’ current signs.
