The Bicentennial National Trail (BNT) is a long non-motorized trail that runs through different types of terrain, including national parks and wilderness areas. Originally intended for horses, the BNT is now also promoted for cycling and walking.

The Trail connects eighteen of Australia’s national parks and more than fifty state forests, providing access to some of the wildest, most remote country in the world. The Trail is suitable for self-reliant horse riders, walkers, and mountain bike riders. Parts of the Trail, such as the Jenolan Caves to Kosciuszko section, are also suitable for horse-drawn vehicles. The Trail is not open to motorised vehicles or trail bikes, and pets are not permitted. The Trail is divided into twelve sections, each with a corresponding guidebook.
