The Bristol to Bath railway path is 13.9 miles (23.3 km) of flat asphalt along a former railway line: free, open all the time, and almost entirely traffic-free. The plan that makes it a great day rather than a slog is to cycle it one way, then take the train back from Bath Spa to Bristol Temple Meads with your bike.
That one-way trick is the whole point of this page, so let's deal with it properly further down. First, the route itself. The path is maintained and documented by the Walk Wheel Cycle Trust (the charity formerly known as Sustrans, which rebranded in September 2025), and its official figures are worth trusting over the internet's: 13.9 miles, a surface that is 99.7% asphalt, and a route that is 97.6% traffic-free, forming part of National Cycle Network route 4. Because it follows the bed of an old railway, there is nothing you could honestly call a hill on it. We checked the route facts, the railway at Bitton and the bikes-on-trains rules against the operators' own sites in August 2026.

Why one way is the right plan
Here's the honest maths that most write-ups skip. The path is 13.9 miles, so the natural out-and-back is nearly 28 miles. On an ordinary bike, with a cafe stop and a look around Bath, that turns a nice idea into a long, saddle-sore day, and it's why so many people ride the path once and never again.
Ride it one way instead and everything changes. You arrive in Bath with legs left over for the city, and the train back from Bath Spa to Bristol Temple Meads takes about a quarter of an hour. An off-peak single is around a tenner; fares change, so check gwr.com for the live price before you travel. Suddenly it's an easy afternoon: two to three unhurried hours of riding, lunch in Bath, and a train home. If that formula appeals, we've built a whole guide around it in the best day trips from Bristol by train.
Where to join it
The path begins in east Bristol near St Philips, a short ride from Temple Meads and the centre, and threads out through the eastern suburbs before running through open country to Bath. You don't need to hunt for a formal gateway: it's a well-signed spine with dozens of ramps and side entrances along its length, so most locals simply join wherever their neighbourhood touches it and follow the route 4 signs.
One practical note for 2026: the Walk Wheel Cycle Trust has been improving the Bristol end of the path between Trinity Street and Clay Bottom, and by its own account the main construction is complete with only finishing touches remaining, without serious disruption to path users. We found no current closures on the route when we checked in August 2026.
What's along the way
The charity's own route notes pick out the old stations at Warmley and Bitton, and the village of Saltford, and those three are exactly the stops to plan around.
Bitton is the star. It's the home of the Avon Valley Railway, a heritage line running steam and diesel trains on three miles of relaid track about 120 days a year, mostly at weekends plus some school-holiday weekdays. You don't need a running day to make it worth stopping: Bitton station is open every day except Christmas Day, entry to the station building is free, and the buffet serves from 9am daily (closing times vary by season). There are public toilets from 9am to 4.30pm. As a mid-ride cafe stop with steam engines in the yard, it has no rival on the path. Train fares and 2026 running dates are on avonvalleyrailway.org.
Warmley's old station makes a shorter first target from the Bristol end, and Saltford drops you close to the River Avon for the prettiest stretch of the ride, with the path and river keeping loose company most of the way into Bath from there.
Bikes on the train back
This is the fact that makes the one-way plan work, so here it is from GWR's own bike policy: there is space for at least 2 full-size bikes on each train, and on ordinary services bikes are carried first-come, first-served with no booking needed. GWR does recommend reserving a bike space on its long-distance Intercity Express Trains (the London-bound ones that call at Bath Spa and Bristol Temple Meads), where bikes travel vertically in a dedicated compartment, but this is guidance rather than a hard requirement; only the Night Riviera Sleeper makes a reservation mandatory. The simple play: reserve a bike space when you book your ticket if you can, or take a local stopping service, where it's first-come, first-served.
Trains between Bath Spa and Bristol Temple Meads run all day and you'll rarely plan around them; still, on a sunny summer Sunday you won't be the only cyclist with this idea, so a reservation or an off-peak slot is the relaxed choice. GWR published a new cycle policy in September 2025, so gwr.com is worth a glance before a group ride.

Walking it
Can you walk it? Of course, and plenty do, but be honest about the number: 13.9 miles is a serious day's walk on hard asphalt, and unlike a circular route there's no shortcut home from the middle. The better plan is the same one-way logic in miniature: walk a section, not the lot. Bitton to Saltford is the pick, giving you the heritage railway and its cafe at one end and the river at the other, or start at Warmley station and stroll out into the countryside and back. Runners, dog walkers and pushchairs share the path with bikes along its whole length, so keep left and expect polite bells.
FAQs
How long is the Bristol to Bath railway path?
13.9 miles (23.3 km) one way, by the Walk Wheel Cycle Trust's own measurement of its route. It's essentially flat throughout because it follows a former railway line, so most riders do the full distance in two to three unhurried hours.
Is the Bristol to Bath railway path traffic-free?
Almost entirely: the charity's official figures put it at 97.6% traffic-free, with a 99.7% asphalt surface. The short remainder is where the path meets roads at crossings and junctions, mostly at the city ends. It's widely used by families, commuters and new cyclists for exactly that reason.
Can I take my bike on the train from Bath back to Bristol?
Yes. GWR's bike policy provides space for at least 2 full-size bikes on each train, carried first-come, first-served on ordinary services. On its long-distance Intercity Express Trains GWR recommends (but does not mandate) reserving a bike space, so either reserve one when you book or use a local stopping service. The journey from Bath Spa to Bristol Temple Meads takes about a quarter of an hour; check gwr.com for live fares and times.
Is there anywhere to stop on the path?
Bitton station, home of the Avon Valley Railway, is open every day except Christmas Day with free entry to the station building and a buffet serving from 9am, and the heritage line runs trains about 120 days a year. The old station at Warmley and the village of Saltford are the other natural pauses.
Can you walk the Bristol to Bath railway path?
Yes, the whole path is shared use, but 13.9 miles on asphalt is a long day on foot with no easy bail-out points. Walk a section instead: Bitton to Saltford is the best short stretch, with the railway cafe at one end and the River Avon at the other.
Is the path fully open in 2026?
Yes, as far as we could establish in August 2026. The Walk Wheel Cycle Trust's improvement works at the Bristol end, between Trinity Street and Clay Bottom, are essentially finished by the charity's own account, with only finishing touches remaining, and we found no current closure notices on the route.
