Swan Upping

What to expect

Swan Upping is a slow, stately procession rather than a single show. Skiffs crewed by the King's Swan Uppers and those of the Vintners' and Dyers' livery companies, flying flags and with crews in smart uniforms, row upstream from Sunbury towards Abingdon over five days. When a family of swans is spotted, the cry goes up and the boats surround the birds so the cygnets can be lifted out, weighed, measured, checked for injury and returned. In 2026 the route ran from Sunbury on Monday 13 July to Abingdon on Friday 17 July, with stops at locks and bridges along the way.

The story behind it

Since the 12th century the Crown has claimed ownership of unmarked mute swans on open water, once prized as a feast for banquets. In the 15th century the Vintners' and Dyers' companies were granted rights to own swans too, and the annual 'upping' sorted out which birds belonged to whom. Today the purpose is very different: the census monitors the health of the Thames swan population and gives the King's Swan Marker a chance to talk to schoolchildren about wildlife and river care. The tradition of rowing past Windsor Castle with oars raised in salute continues.

Getting there and home

Choose a day and a spot rather than trying to follow the whole route. Windsor & Eton Riverside station sits beside the river near Eton Bridge, the departure point on the second day. Marlow, Henley-on-Thames, Goring & Streatley and Shepperton all have stations close to the published stopping points. Morning departures are around 8.30 or 9am, but arrival times further upstream depend on how many swans are found, so allow plenty of leeway.

Watching, taking part and tips

Locks make the best viewing points, because the boats must stop and wait, giving you a close look at the crews and, with luck, a cygnet being checked. Bridges give a good overview. Bring a picnic, sun hat and binoculars, and be ready to wait. This is a working wildlife survey, so keep dogs on leads and give the birds space. Children love it, especially if they arrive early enough to see a family being rounded up.

Where to watch

The Dyers' Company explains the colours you'll see: the King's team in red, the Vintners in white and the Dyers in blue. Each has its own boats and identifying flag, and the crews are experienced Thames Watermen, often with family links to earlier Swan Uppers. It makes a nice little spotting game while you wait for a swan family to be found. Watch how the boats position themselves and how the crews work together, rather than expecting a race between the colours. For children, picking out a flag or uniform is an easy win even when the swans themselves are hard to see. Keep binoculars or a camera ready from your spot, and stay off the landing place used for handling the birds. The work needs room for people, equipment and swans to move about safely.

Accessibility and families

The Royal Household explains that young swans belonging to the Vintners or Dyers are given individually numbered identification rings, with ownership decided by their parents, while Crown birds are left unmarked. That gives the checks real meaning — otherwise they can look like an elaborate pause in a rowing trip — and explains why old accounts of beak marks aren't a guide to what you'll see today. The Household puts education at the heart of the work, with organised school visits exploring habitat, biology and equipment. Families watching on their own won't necessarily get into those sessions, but the same themes make good conversation on the bank. Let children watch what's going on and save their questions to look up afterwards, rather than interrupting someone who's holding a bird or noting down information.

A brief timeline of the day

The Vintners' Company publishes an outline of the journey upriver, naming locks, bridges and towns, but says plainly that the schedule depends on river conditions. Use it to understand the route rather than as an appointment for a future year. Get a dated itinerary, and choose a spot you can reach and leave easily if progress changes. If you're thinking of watching from a boat, check the Environment Agency's live river-condition warnings as well as the organisers' plan; the Agency also points boaters to closures and restrictions, and a lovely afternoon on the bank says nothing about conditions on the water. On the bank, allow yourself a flexible waiting window and know where you'll go for refreshments or a break. Steer clear of a tight onward booking that turns a leisurely wildlife survey into a dash for the station.

Make a day of it nearby

If you're near the Cookham and Maidenhead stretch of the route, try the Stanley Spencer Gallery in Cookham or Cliveden near Taplow. The gallery has changing exhibitions linked to Spencer's work, so check what's on and when rather than hoping a particular painting will be up during Swan Upping. Cliveden's National Trust grounds have formal gardens, sculpture and woodland above the Thames, with their own admission and visitor arrangements. Go to the gallery for some indoor art, or the estate for a longer wander through gardens. Neither is an official viewing spot for the census, and a ticket doesn't guarantee a glimpse of the Swan Uppers. Keep either visit separate from your waiting window, especially if you've booked a timed entry. Think of them as alternatives for the rest of the day, not reasons to chase the skiffs from stop to stop.
