Please note: Due to rising water levels, the Devonshire Tunnel is currently closed. There is significant flooding due to recent rainfall overwhelming a nearby damage drain that's awaiting repair. We’ll continue to monitor the water levels to determine when it's safe to reopen. Thank you for your patience.
The iconic Bath Two Tunnels Circuit is a 13-mile walking and cycling loop through beautiful green spaces.
It’s an ideal day out for families walking, wheeling or cycling.
The route takes you from the centre of historic Bath through two tunnels, over the spectacular Tucking Mill Viaduct.
It passes the Dundas Aqueduct on the Kennet & Avon Canal, until you are back alongside the River Avon, closely following it back into Bath.
You'll pass the Combe Down Tunnel which is an awe-inspiring sight.
It stands at an impressive 1,672 metres, is just over one mile and is the UK's longest cycling and walking tunnel.
Travelling through the Combe Down Tunnel for the first time is an incredible experience.
And it's heightened by the extraordinary audio-visual installation, ‘Passage’ by United Visual Artists.
A Portrait Bench sits at the entrance of the Devonshire Tunnel, so keep an eye out for it.

The history of the route
The two tunnels project was part of the Sustrans Connect 2 National Lottery funded project.
It is one of the biggest of all the 84 projects across the UK.
This project would not have become a reality without the incredibly dedicated Bath Two Tunnels group.
