When visiting Serbia’s countryside, national parks, and river areas, stay on marked paths, avoid littering, and do not pick wildflowers or disturb wildlife, as nature spots are treated as shared public spaces that people expect to remain clean and intact. In protected areas such as
Đerdap National Park or
Tara National Park, locals are especially protective of forests, viewpoints, and picnic sites, and it is normal to keep noise low and leave the area exactly as you found it.
