The iconic Bath Two Tunnels Circuit is a 13-mile walking and cycling loop. It’s an ideal day out for families on foot or by bike.
The route takes you from the centre of historic Bath through two tunnels, over the spectacular Tucking Mill Viaduct and past the Dundas Aqueduct on the Kennet & Avon Canal, until you are back alongside the River Avon, closely following it back into Bath.
The Combe Down Tunnel, 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, heightened by the extraordinary audio-visual installation, ‘Passage’ by United Visual Artists. A Portrait Bench sits at the entrance of the Devonshire Tunnel.
You can start this circular route at any access point along the circuit.
A recommended start point is either Bath Spa station or Oldfield Park station. Both are a short ride from the route, which can be ridden in either direction.
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.
