Yes, it matters for what you are allowed to do when you're in nature.
Let's start with the rules: As a general rule, you are allowed to walk on trails and roads through forests and along beaches, whether you're on private or public land. You can walk on private beaches but cannot stop or linger. In private forests, you are allowed to walk on trails from 6 a.m. until sunset. You are not allowed to stop or linger within 150 meters of buildings in private forests. In forests smaller than 5 hectares, private landowners can deny public access. If this is the case, it must be clearly marked at the entrance to the forest. Generally, you can always tell if a forest is public or private by the signs at the entrance.
In public forests, you can walk off-trail on foot at any time, but you must follow any signage.
Tips: Always respect privacy and do not enter private land. Think of it as being a guest in someone else’s home when you walk through their forest. Pass through as much as possible, but avoid stopping. In general, the presence of facilities like picnic tables or marked routes is a good indicator that the owner is okay with you stopping on the property.
