267 Frome to Bath serves the south end and can return you to the city centre, allowing you a one-way walk (closest stop Hope and Anchor Midford).
The 94 serves Monkton Combe and many other villages, and allows you all sorts of adventures. For ideas, check our welcome page.
Oldfield Park Station is closest to the route.
Newbridge Park and Ride (BA1 3NB) is recommended. Leave your car at the park and ride and head east along the Upper Bristol Road in the direction of the city, and then take the first right (Brassmill Lane) then on to the river towpath. Lastly, following signs, cross the green steel footbridge over the river.
You'll find many options for accommodation in Bath. Note that Travelodge, the budget hotel chain has three in the city centre and one of them, Travelodge Bath Waterside, at the south side of the city centre, is well situated for the route, within a few minutes walk of the railway station, has the shops and businesses of Widcombe High Street across the road, and is beside the canal - one of the best towpath walks in the UK is close at hand.
