HEADS UP: Rare chance to step inside historic Lapstone Hill Tunnel
Blue Mountains City Council is inviting the community to step inside one of the City’s great hidden heritage treasures, with the historic Lapstone Hill Tunnel opening to the public for one weekend only.
The Lapstone Hill Tunnel Open Weekend will be held on Saturday 25 and Sunday 26 July, giving residents and visitors a rare opportunity to explore the tunnel, learn more about its history and see the vision to return it to the community as a safe, accessible place for walking, cycling, recreation and events.
A program of activities will run across the Open Weekend, giving people different ways to experience the tunnel and surrounding precinct.
The weekend will include a trail run and a breakfast ride-through, showcasing the tunnel’s future potential as part of a safe and scenic walking and cycling connection between the Blue Mountains and Western Sydney.
Council is seeking funding and investment to complete the works needed to safely reopen the tunnel and surrounding precinct. This includes remediation works, pathway connections, lighting, safety treatments, amenities, car parking, landscaping and accessible links.
Constructed in 1892, the heritage-protected tunnel sits within a high conservation bushland setting at the eastern gateway to the Blue Mountains. Once part of the region’s railway history, the tunnel has long been dormant and is usually closed to the public.

Council first opened the Lapstone Hill Tunnel to the community in 2024, attracting more than 1,500 visitors in one day.
After the open weekend, the tunnel will close again until the necessary infrastructure and remediation works are funded and completed.
Registrations are essential.
