Syon House, the great Adam interior on the Brentford riverbank, opens on only three days a week during its season: Sundays for self-guided entry from 10.30am to 3.30pm, and Mondays and Tuesdays for guided tours only, the first at 10.30am and the last at 2pm. Adult admission is £16.50 booked online or £17.50 at the door. Turn up on a Wednesday and the gates are shut.
Brentford and Isleworth face Kew Gardens across the Thames, and the Grand Union Canal comes down to meet the river between them. That geography is the whole reason to come: a stretch of working waterway, two eighteenth-century estates, two small museums about how Victorian London was supplied, a Jacobean manor house that costs nothing to enter, and a Premier League football ground built on the site of a market garden.
It is not a pretty neighbourhood in the Richmond sense. Brentford's high street has been rebuilt around it and the traffic on the A4 and the A315 is constant. But the individual things here are good, several of them are free, and almost all of them have restricted opening days, so this page leads with the calendar rather than the scenery.

Syon House, and the three days it opens
Syon is the London home of the Dukes of Northumberland and the reason architects come to Brentford. Robert Adam remodelled the interiors in the 1760s inside a much older shell, and the sequence of rooms behind the plain battlemented exterior is one of the most complete Adam schemes anywhere.
The opening pattern is unusual and needs stating plainly. During the season the house opens on Sundays and bank holidays for self-guided visits from 10.30am to 3.30pm, with last entry at 2.30pm. On Mondays and Tuesdays it opens for guided tours only, up to ninety minutes long, with the first tour at 10.30am and the last at 2pm. It does not open Wednesday to Saturday. The estate does not publish a single season-end date on its opening page, so check the date calendar before you travel.
An adult pays £16.50 for the house, gardens and Great Conservatory if booked online, and £17.50 at the door. The gardens and conservatory on their own are £7.00 or £8.00. The full price list, including the family ticket and what a family of four actually pays, is on our Syon House page, along with the access warning that matters if anyone in your party cannot manage stairs.
The gardens-only ticket is the best value in Brentford. For £7.00 booked ahead you get Capability Brown's parkland, the lake and the Great Conservatory, a curved iron-and-glass building from the 1820s that predates the Palm House at Kew. If the house is closed on your day, or the family budget will not stretch to £48, this is the visit to make.

Two museums about water and music, and neither opens on a Monday
The London Museum of Water & Steam is on Green Dragon Lane, TW8 0EN, in the buildings of a Victorian pumping station that supplied west London with drinking water. It holds one of the world's best collections of working steam engines, and the point of the place is that several of them still run.
It opens Thursday to Sunday from 10.00 to 16.00, with last entry at 15.00, and an adult pays £12.00 with children aged 5 to 16 at £4.00. There is a hands-on Waterworks Gallery and an outdoor Splash Zone, which makes it the best thing in Brentford for young children. Two caveats belong on the day you choose: the Great Engine House, which holds the 90-inch and 100-inch engines, is shut for a long renovation, and which engines actually run under steam depends on the date.
The Musical Museum, at 399 High Street, TW8 0DU, is a twenty-minute walk south-east and is a genuine oddity: three galleries and a 250-seat concert hall full of self-playing instruments. Pianos that reproduce recorded performances, a violin that plays itself, pipe organs, music boxes, gramophones, a jukebox that plays 78s, a Wurlitzer cinema organ, and a whole gallery of synthesisers. Volunteers demonstrate them on guided tours, which is the only sensible way to see it, because the collection is silent otherwise.
It opens Friday, Saturday and Sunday from 10am to 4pm, with tours at 10.30am, 12.30pm and 2.30pm, and tickets are bought at reception on the day rather than online. An adult pays £15.00 and a child £5.00. The tour takes just over an hour and there is a café with river views. Our guide to the Museum of Water and Steam and the Musical Museum has the family prices, the concert and silent-film programme, and a plan that fits both museums into one day.
Boston Manor House, which is free and almost empty
The best-value building in this part of London is a Jacobean manor house of 1623, three storeys, Grade I listed, set back from Boston Manor Road in a park with a lake and old cedar trees. It reopened after a long restoration paid for by the National Lottery Heritage Fund, Historic England, the Greater London Authority and several trusts.
Entry is free, and it opens Tuesday to Sunday from 12 noon to 5pm. Hounslow Council runs it. Boston Manor station is on the Piccadilly line, Zone 4, about seven minutes' walk, which makes this the easiest thing in the area to reach from central London without changing trains.
Put it with Syon and you have two great houses within three miles of each other and about a hundred and forty years apart, one of them free. If you want a third, Osterley Park and House is the other Adam house in the borough, two stops further out on the Piccadilly line, and its opening hours are shorter than most people expect.
The canal, the river and the walk between them
The Grand Union Canal reaches the Thames at Brentford, and the last mile of it is the best walking here. Locks, moored narrowboats, the old dock basin, and a towpath that runs north-west towards Southall and beyond. Walk south and you come out at the river opposite the Kew Gardens boundary wall, with the Thames Path continuing towards Isleworth.
The riverside stretch through Isleworth is the prettiest part of the whole area: a short run of eighteenth-century houses, a church at the water's edge, and a view across to Isleworth Ait, a wooded island in the Thames. At low tide the foreshore is exposed; note that looking at what the river uncovers is legal, but searching or digging for objects is not, and the Port of London Authority has suspended both mudlarking permits and its waiting list, as our page on mudlarking on the Thames foreshore explains.
Kew Gardens is directly across the water and feels close, but there is no bridge at that point: the crossings are Kew Bridge to the east and Richmond further upstream. Our page on how long Kew Gardens takes makes the case for not trying to bolt Kew onto a Brentford day, and the Thames Path guide has the walking routes.
Brentford FC and the Gtech Community Stadium
Brentford play in the Premier League in the 2026/27 season, one of only six London clubs that do, and the ground sits between the railway and the canal at Lionel Road, a few minutes from Brentford and Kew Bridge stations. It replaced Griffin Park, the old ground famous for having a pub on each of its four corners.
Stadium tours run on selected dates through the season and cost £20.00 for an adult and £10.00 for a concession, which covers under-18s and over-65s. They take you into the first-team changing rooms, through the tunnel and into the dugout. Match tickets are a different matter entirely, and our guide to Premier League football in London explains how each London club sells them and why a neutral rarely gets a seat.
One practical warning if you are visiting the museums on a match day: the London Museum of Water & Steam closes its car park on Brentford home fixtures, and the roads around Kew Bridge fill up. Come by train.
Getting here, and the station to choose
Two railways serve the area and they do different jobs. South Western Railway from Waterloo stops at Brentford, Kew Bridge, Syon Lane and Isleworth; Brentford, Syon Lane and Isleworth are Zone 4 and Kew Bridge is Zone 3. The Piccadilly line reaches Boston Manor, Osterley and South Ealing on the other side of the A4.
Choose by destination. Boston Manor station for Boston Manor House. Kew Bridge or Gunnersbury with a bus for the Museum of Water & Steam, which also names buses 65, 237, 267 and 110. Brentford for the football ground, the canal and the Musical Museum. Syon Lane or Isleworth for Syon House and the riverside.
None of the South Western stations here has a lift or a ramped route in TfL's station dataset, and neither does Boston Manor. Osterley has two lifts. That makes step-free travel genuinely difficult in this area, and our guide to step-free transport in London explains what to do when the nearest station will not work.
Is it worth the journey
Come if
- Georgian interiors interest you and you can come on a Sunday, Monday or Tuesday
- You like working machinery, and can come Thursday to Sunday
- You want a free Jacobean house with almost nobody in it
- You are walking the Thames Path or the Grand Union towpath
- You have a Brentford ticket and half a day before kick-off
Skip it if
- Your only free day is a Wednesday
- You want a handsome high street; Richmond and Chiswick have those
- You are short of time and have not yet done central London
- Step-free travel is essential and you cannot use Osterley
The obvious neighbours are Chiswick and Kew to the east and Twickenham and the Richmond riverside upstream, both of which are better for eating and for the river itself. Brentford is where you go for the specific thing, not for the afternoon.
Frequently asked questions
What days is Syon House open?
During its season, Sundays and bank holidays for self-guided entry from 10.30am to 3.30pm with last entry at 2.30pm, and Mondays and Tuesdays for guided tours only, the first at 10.30am and the last at 2pm. The gardens and Great Conservatory open on all three of those days. The house does not open from Wednesday to Saturday.
How much does Syon House cost?
An adult pays £16.50 online or £17.50 at the door for the house, gardens and Great Conservatory, and £7.00 or £8.00 for the gardens and conservatory alone. Children and family tickets cost considerably less, and the full table is on our dedicated Syon House page.
Is there anything free to do in Brentford?
Boston Manor House, a Jacobean manor of 1623 in its own park, is free and open Tuesday to Sunday from 12 noon to 5pm. The canal towpath and the Thames Path through Isleworth cost nothing, and so does walking round the outside of the football ground.
Can you see Kew Gardens from Brentford?
You can see across to its boundary and its trees from the Brentford riverside, but there is no crossing at that point. The nearest bridges are Kew Bridge downstream and Richmond upstream, so treat Kew as a separate day rather than an add-on.
Is the Musical Museum worth visiting?
If mechanical instruments or early recorded sound interest you at all, yes, because the volunteers demonstrate the machines and the collection is meaningless silent. It opens only Friday to Sunday from 10am to 4pm with tours at 10.30am, 12.30pm and 2.30pm, tickets are bought at the door, and an adult pays £15.00.
