Many people enjoy cycling along the Kennet and
Avon Canal towpath.
There are several pleasant routes into Bath avoiding the city
traffic:
From the west:
The Bristol and Bath Railway Path forms part of the "Sustrans"
route 4. The path is 19kms long and level nearly throughout,
offering a very pleasant path for cycling or walking between the
two cities.
