Grantchester Meadows and wild swimming used to feel like a fairly simple combination.

Then came 2021.

King’s College put up signs restricting swimming, paddling and the launching of watercraft on the River Cam, and one of the area’s best-known summer traditions suddenly became a local argument.

So what is the position now?

The slightly frustrating answer is: don’t rely on what you remember from a few summers ago.

The 2021 restriction was real. The row that followed was real too. But the later public position became much less clear-cut than the original headlines suggested.

If you are heading there now, the important thing is the current sign at the access point you are actually using.

Why did King’s step in?

The college said the problem was not simply people having a swim.

Its concerns included large gatherings, alcohol and drugs, emergency call-outs, litter, damage to the riverbank and the question of responsibility if somebody got into trouble.

In other words, the issue was as much about what was happening around the water as what was happening in it.

That distinction got rather lost once the word ban started appearing.

And people were not happy.

More than 8,000 people were reported to have signed a petition calling for swimming access to remain.

For a patch of meadow and riverbank, this became a surprisingly big local row.

Then the message changed

A later joint statement involving King’s and local councils said revised signs would make clear that there had been no wish to ban swimming altogether.

The emphasis shifted towards responsible use:

take your rubbish home,
avoid barbecues,
respect the riverbank,
and do not turn a popular summer spot into a free-for-all.

That softened the original story considerably.

But it did not produce the wonderfully simple answer everybody would prefer today: yes, you can swim here or no, you cannot.

So what does King’s say now?

King’s still owns the meadows.

In 2025, it announced that day-to-day management was moving to Cambridge Past, Present & Future as part of a new partnership responding to rising visitor numbers and competing uses of the site.

That announcement mentions activities including swimming and punting.

What it does not do is clearly say whether the old 2021 restriction has formally disappeared, been replaced or still applies in some form.

And that is why the sign in front of you matters more than an old Facebook argument.

Before you get in the water

There are really three separate things to check:

Is swimming allowed at this exact spot?

Is it safe today?

Can you legally launch or land a paddleboard or boat here?

Those are not necessarily the same question

.

The Conservators of the River Cam identify parts of the upper Cam as suitable for swimming, while also warning about restrictions around locks, sluices and weirs.

That does not mean every bit of riverbank is automatically open for swimming or launching.

And even where access is permitted, conditions can change.

Cold water, slippery banks, hidden debris, weeds, uncertain depth and waterborne illness can all turn a calm-looking stretch of river into something much less friendly.

The Grantchester rule worth remembering

Do not assume that because people swam there five years ago, they can today.

Do not assume that because somebody else is in the water, the access point is allowed.

And do not assume that a river safety warning, a landowner notice and a navigation restriction all mean the same thing.

Read what is actually posted where you are.

Check the latest official advice.

And if it is unclear, choose another spot rather than trying to win an argument with a sign.

Why the row still matters

The Grantchester dispute was never only about swimming.

It was about what happens when one of the area’s most loved summer spots becomes busier, noisier and harder to manage.

People want access.

Landowners want some control.

The river still needs protecting.

And everybody would benefit from clearer rules.

So the real question is no longer simply:

“Did King’s ban swimming?”

It is:

“What are you actually allowed to do there now?”

If you visit Grantchester Meadows, tell us what the current signs say at the access point you use especially if they treat swimming, paddling and launching differently.
