Starting from the Boxvale Tramway Walking Track car park off Boxvale Road, Mittagong, this walk takes you to the Nattai Gorge Lookout and back via the Boxvale Tramway Walking Track. This moderately challenging bushwalk follows the route of a historic railway line used to transport coal from Welby to the Nattai escarpment in the 1800s. Although the tramway and its bridges are long gone, the boulder cuttings, embankments and tunnel remain. The track winds its way around the Nattai and Kells creeks, passing through lush forest, fern-lined valleys, and along paths carved out between the cliffs. After passing through a long tunnel carved through the rock, the track reaches a lookout with stunning views over Nattai Gorge, the Nattai River and towards the Blue Mountains. The track is well-signposted and easy to follow, with several picnic tables along the way. There's also a swimming hole near the start of the track. While some of the boulder-carved sections are clear, others require navigating fallen trees, rocks and mildly overgrown areas. This walk consists of wide and narrow, mostly flat walking trails, with uneven natural surfaces, compacted natural surfaces, suitable for average fitness levels. Let us begin by acknowledging the Traditional Custodians of the land on which we travel today, and pay our respects to their Elders past and present.
