Grenofen Tunnel

The Grenofen tunnel is a 374-yard (341 m) tunnel that was built by Brunel in the mid-1850s for the South Devon & Tavistock Railway. It is located in Grenofen, a hamlet about 2 miles south of Tavistock on the A386 at the southwestern edge of Dartmoor National Park. The tunnel was part of a railway line that connected Plymouth with Tavistock and Launceston, but it closed to services about 50 years ago.
Today, the tunnel forms part of the Tavistock to Plymouth cycle route, which is also known as the Drake’s Trail. The tunnel is lit and open for cyclists and pedestrians. It offers a fun and scenic way to explore the park and its history. The cycle route also includes the Gem Bridge, a £2m viaduct that crosses the River Walkham, just south of Grenofen.
The Grenofen tunnel is a great example of how an old railway structure can be reused and enjoyed by the public. It is also a testament to Brunel’s engineering skills and vision.

Drippy! Fun or spooky. Either way in and out QUICK!

I have ridden this track many times, always have a light on the front as some people ride through here too fast, and there are pedestrians walking through as it's a shared track.
