Bath sits about an hour and a half west of London Paddington by direct train, which makes it one of the easiest full days out from the capital. Adding Stonehenge to the same day is also common, but it changes the shape of the trip completely: the stones are out on Salisbury Plain, roughly an hour from Bath by road and awkward to reach without a car or a coach. This plan does both, with Stonehenge first thing and the rest of the day on foot in Bath.
It suits anyone who wants one prehistoric landmark and one very walkable Georgian city in the same twelve hours, and who does not mind an early start.
Is it worth a day trip?
Bath alone is close to a perfect day trip. The centre is compact, the sights are minutes apart, and the journey each way is short enough that you arrive with the morning intact.
Stonehenge is the part that needs thought. By public transport it means a train to Salisbury and then the seasonal tour bus out to the site, which is a long detour to fold into a Bath day. If Stonehenge matters to you, either drive, take an organised coach from London that covers both, or give Salisbury and the stones their own separate day.
Stay overnight instead if you want the Georgian city at its best. Bath in the evening, once the coaches have gone, is a different and quieter place, and the abbey and the crescents look better in low light. The journey-time arithmetic behind that call is in how far is too far for a day trip.
Getting there
Great Western Railway runs direct trains from London Paddington to Bath Spa, calling at Reading, Didcot Parkway, Swindon and Chippenham. The journey is roughly an hour and a half, with services through the day. Tickets come from GWR or any national rail retailer, and advance fares on a fixed train are usually the cheapest way to travel.
Bath Spa station is a five minute walk from the abbey, so no onward transport is needed once you arrive. For Stonehenge, the practical options are a car, a coach tour from London, or a train to Salisbury followed by the Stonehenge tour bus.
The day, hour by hour
09:30 Stonehenge. The stone circle stands alone on open chalk downland, and the approach from the visitor centre, on foot or by shuttle, is part of the effect. Allow about two hours for the exhibition, the walk out and a slow circuit of the stones. Entry is timed, so the slot you book decides your morning.
12:00 the Roman Baths. The Great Bath, still fed by the hot spring, is the centrepiece, but the route also takes you past the temple courtyard, the spring overflow and rooms of Roman finds. Give it an hour and a half, and use the audio guide rather than rushing the lower level. This is the single thing most people come to Bath for.
13:30 Bath Abbey. Next door to the baths, the abbey is late Perpendicular Gothic at its most confident: a fan vault overhead and carved angels climbing ladders on the west front. It is a working church, so services can close it to visitors at short notice.
14:30 Pulteney Bridge. Five minutes north east, the bridge carries shops along its whole span, one of very few in Europe that still do. The view most people want is from the terrace on the far side, looking back at the weir stepping down the Avon.
15:15 the Royal Crescent. A fifteen minute uphill walk brings you to the great sweep of thirty terraced houses facing an open lawn. Number 1 Royal Crescent is furnished as a Georgian townhouse and can be visited; the rest is private, and the point is the facade and the space in front of it.
16:00 the Circus. Just along Brock Street, the Circus is the Royal Crescent's circular counterpart, three curved terraces around a ring of plane trees. Walk right round it and look up at the carved frieze, which runs the whole way without repeating.
17:00 Sally Lunn's. The day ends back in the centre at one of the oldest houses in Bath, known for the large soft bun that carries its name. There is a small kitchen museum in the cellar. If the queue is long, the streets around it are full of alternatives, and the station is a few minutes away.
What to book ahead
Book Stonehenge entry in advance, since admission is by timed slot and the site is popular. Roman Baths tickets are worth booking for a specific time in summer and at weekends. Everything else on this day can be decided as you go.

The whole day is saved as a plan you can open, with the stops in order and every one of them on a map, so you can see how the walking actually links up before you go.
Open the Bath and Stonehenge day trip plan. It opens on a map without an account, and you can change it: drop Stonehenge and start later, add an afternoon at the Holburne Museum, or move the Royal Crescent earlier to catch better light. Share the link with whoever you are going with and they will see the same plan.
If you are weighing Bath against a shorter journey, the Oxford day trip from London is an hour each way and covers similar ground for architecture. More routes are collected in all our day trips, and the method behind them is in how to plan a day trip.
