The iconic Bath Two Tunnels path is a unique experience. The flat route follows the old Somerset and Dorset Railway which closed in 1966.
In 2013, and with the help of the Two Tunnels Group and partners, we were able to reopen the tunnels as a shared-use path.
Today, the 13-mile loop is an ideal day out for families. Play areas, picnic spots and architectural wonders dot the route.
And what of the tunnels?
The Devonshire Tunnel curves its way from Bath city centre into a deep wooded valley. It is followed by the second longer and more impressive Combe Down Tunnel.
At 1672-metres in length, it is the longest walking and cycling tunnel in the UK. Combe Down also boasts its own light and sound artwork.
Both are well lit and surfaced.
