The Fernleigh Track is a multi-use rail trail near Belmont, New South Wales. The track was constructed in the way of the former Belmont railway line. The project is a joint venture between Newcastle City Council and City of Lake Macquarie. The track extends from Adamstown to Belmont over a distance of 15.5 km (10 mi). The railway closed in December 1991. The first section between Adamstown and Burwood Road opened in 2003. Construction continued in stages with the final section between Jewells and Belmont completed in March 2011.
The first section of the Belmont railway line opened in 1882 to Redhead, with the line being extended to Belmont in 1917. At one stage, there was talk of extending the line to Swansea.
A feature of the conversion of the former railway to a multi-use trail is the retention of many industrial heritage features. The trail passes through the brick-lined Fernleigh Tunnel under the Pacific Highway.
At the site of the former Kahibah station, the cycleway is crossed by the Great North Walk, a 250 km (155 mi) walking trail connecting Newcastle and Sydney. The track also passes through the centre of the Glenrock Lagoon catchment.
The track is used by cyclists, wheelchair users, walkers, runners, and dog walkers. Motorized vehicles, including motorcycles, are prohibited on the track. It also hosts community events such as the annual Fernleigh 15 running race, which is held along its full length.
The Fernleigh Tunnel is one of the most significant historic features of the track. It is located between Adamstown and Belmont and passes beneath the Pacific Highway, serving as a connection point between Newcastle and Lake Macquarie region.


Constructed in the early 1890s and opened in November 1892 as part of the Belmont railway line, the 180 metres brick-lined tunnel has a curved alignment to maintain acceptable railway gradients while passing beneath the Pacific highway. By 1992, the tunnel ceased to be a railway tunnel and was reopened as part of the Fernleigh track by 2003 for cyclists and pedestrians. Lighting has been installed inside the tunnel to improve visibility and safety. The Fernleigh Tunnel has been featured in several Australian television commercials.
