The railway heritage walk involves a two hour walk along the path of the legendary North Australia Railway. Starting from Stuart Estate, 5 kilometres north of Katherine, the walk passes fascinating geological formations that the railway surveyors skirted. The walk continues through Conroy's Gap to the historic location of Emungalan, which was established as the railhead town to service the area before the high level railway bridge was constructed to cross the Katherine River.

This rail trail begins at the former Katherine railway station. After crossing the historic Katherine River railway bridge the trail borders the Stuart Highway, for 5.2km to Morey Rd on a new section opened in 2011. The centre of the trail is the former railway station and the nearby impressive bridge over the Katherine River. The station has several reminders of its past days and a steam locomotive is on display near the bridge.

At several locations the trail deviates from the formation to preserve the rails and Carnegie steel sleepers as heritage features. Railway culverts and bridges have been retained. Part of the path—including a bridge—has been decked in steel mesh so the rails and three different types of sleepers are visible to users. Solar powered lights have been installed over the bridge.
