At 3.0 km, this is a short, accessible outing suitable for most fitness levels. Expect to complete it in around 40 minutes at a comfortable pace.

The route forms a complete loop, returning you to where you started. This makes logistics simple and the outing entirely self-contained. Follow the AR 02 waymarkers throughout to stay on the official trail line.
