Combe Down Tunnel

Highlight • Structure

Part of the Two Tunnels Greenway walking and cycling path, Coombe Down Tunnel is known to be the longest cycling tunnel in Britain and, therefore, by extension the longest running tunnel in Britain too. Around a mile (1.7 km) in length, it runs below Bath's southern suburbs, emerging below Coombe Down village. The tunnel was originally part of the Somerset and Dorset joint railway line.

Two Tunnels Greenway

Highlight • Structure

Fantastic bike path going through the famous two tunnels. The longest bike path tunnel in the UK. Although it is lit the lighting is poor so lights are highly recommended to avoid collisions. Great spot for some on ride karaoke if you love the sound of your own voice (echos).
