Some of London’s best family spots don’t announce themselves. A free museum with two and a half thousand years of history under one glass roof. A seven-acre park where, by law, adults aren’t allowed in unless a child brings them. A square that turns into a free water park the moment the sun comes out. None of it costs anything to get into, and all of it sits within a short, flat ride of each other through Bloomsbury and King’s Cross.

Before you roll

• Distance: roughly 6–8km round trip from Mayfair, flat throughout.
• Timing: the British Museum opens 10am–5pm daily, and until 8:30pm on Fridays if you fancy a quieter evening visit without the kids. Coram’s Fields is open from 9am until dusk in winter, or as late as 8pm in summer.
• Cost: all three stops are free. The British Museum suggests an optional £5 donation on entry; its major ticketed exhibitions (the Bayeux Tapestry is showing from September 2026 through July 2027) are separate and need booking.
• The Coram’s Fields rule: this is the one to know before you go — no adult may enter Coram’s Fields unless accompanied by a child under 16. It’s been the rule since the park opened in 1936, and it’s still strictly enforced. Bring your kids, obviously, but don’t plan on popping in alone while they nap in the box.

The British Museum: free, enormous, and older than most countries

~15 minutes from Mayfair

The British Museum’s Great Court — a vast glazed courtyard wrapped around the old circular Reading Room — is worth a stop on its own before you’ve seen a single exhibit. From there, the collection is genuinely staggering: the Rosetta Stone, the Egyptian mummies (a reliable favourite with children of almost any age), and the Parthenon sculptures, all free to walk up to with no ticket required for general admission.

Don’t try to see all of it in one visit. Pick a wing — Egypt is the easiest sell to most kids — and treat the rest as a reason to come back.

Coram’s Fields: the park that needs a child to get in

~10 minutes from the British Museum

Coram’s Fields is one of London’s genuinely odd, wonderful institutions: seven acres of park, playground and small city farm in the heart of Bloomsbury, and adults are only allowed through the gate if they’ve brought a child with them. It was founded on the site of London’s old Foundling Hospital in 1936, specifically as a green space for children, and the rule has outlived nearly a century of London development around it.

Inside, there’s a proper adventure playground with an aerial zip line, sandpits, a paddling pool that opens in summer, and a small city farm with goats, sheep, rabbits and chickens that kids can get genuinely close to. It’s free, it’s shaded by mature trees, and there’s a café if the adults need a sit-down.

North to King’s Cross

The ride up to King’s Cross follows quiet Bloomsbury streets before opening out onto the Regent’s Canal towpath for the last stretch — flat, mostly car-free, and a pleasant change of pace after two stops indoors and behind railings.

Granary Square: 1,080 fountains and nowhere to hide

~15 minutes from Coram’s Fields

Granary Square is the centrepiece of the King’s Cross redevelopment, and its main draw for families is entirely free: 1,080 individually lit, individually controlled fountain jets set into the paving, choreographed to rise and fall in patterns through the day. On a warm afternoon it turns into an unofficial urban beach — kids soaked to the skin, running between the jets, while everyone else watches from the steps with a coffee. At dusk the whole square lights up in colour, which is worth timing a visit around if you can.

Bring a full change of clothes. We mean it.

Frequently asked questions

Can adults visit Coram’s Fields without a child?

No. Coram’s Fields has operated under a strict rule since 1936: no adult may enter unless accompanied by a child under 16. It’s one of the only parks in London with this restriction, and it’s still enforced today.

Is the British Museum free to enter?

Yes. General admission to the permanent collection is free, with an optional £5 donation suggested at entry. Major special exhibitions, such as the Bayeux Tapestry showing from September 2026 to July 2027, are ticketed separately.

Are the Granary Square fountains free?

Yes. The 1,080 fountain jets at Granary Square in King’s Cross are free to visit and run daily, with no booking required. They’re a popular spot for children to cool off and play in warm weather.

Is this route suitable for younger children?

Yes — it’s flat throughout, roughly 6–8km round trip, and all three stops are outdoor- or ground-floor-friendly for pushchairs and younger legs.
