We should tell you upfront: if you do the whole loop and you stop at the Diana Memorial Fountain, your child will get completely drenched. Not a little wet. Soaked. Shoes, socks, everything. Bring a change of clothes and embrace it, because the look on their face when they discover they’re allowed to paddle in a public park in central London is absolutely worth the wet bag on the way home.

That’s the ending. Here’s how you get there.

Before you roll

• Distance: approximately 10–12km, flat throughout.
• Timing: Start around 9am to catch the Changing of the Guard at 10:45am on Mondays, Wednesdays and Fridays. Always check the morning of — it can cancel.
• Battersea Park Children’s Zoo: open from 10am, closes 5:30pm. Pre-book at batterseaparkzoo.co.uk.
• Albert Bridge: currently closed to motor traffic due to structural repairs, but open to cyclists and pedestrians. Status may change — check rbkc.gov.uk before you go.
• Diana Memorial Fountain: open from 10am. Bring a change of clothes for the little one.

St James’s Park: the pelicans have been here longer than you think

The day starts gently at Green Park, then rolls straight into St James’s Park — arguably the finest of London’s eight royal parks. The lake, the willow trees, the view across to Buckingham Palace on one side and the towers of Whitehall on the other. It’s one of those spots that makes you feel glad to be in London even if you’ve lived here for years.

The pelicans have been in residence since 1664, when a Russian ambassador gifted the first pair to King Charles II. They are enormous, unhurried, and completely indifferent to small children trying to get their attention. Which of course makes small children want their attention even more.

Feed the ducks. Watch the pelicans. Ease into the day.

The Changing of the Guard: stand at St James’s Palace, not Buckingham Palace

Here’s the thing most people don’t know: the ceremony starts at St James’s Palace, not at the Palace down the Mall. At 10:30am on Mondays, Wednesdays and Fridays, the Old Guard forms up right here — in front of you, no barriers, no crowds — before marching away to Buckingham Palace with the band playing. It’s free, it’s surprisingly moving, and it’s over in about fifteen minutes.

If the timing doesn’t work, or if the toddler is more interested in the small playground in the park, skip it without guilt. The rest of the day is excellent regardless.

Victoria Tower Gardens: the hidden pitstop

Most people cycle straight past this one. Don’t. Tucked along the Millbank, in the shadow of the Houses of Parliament, Victoria Tower Gardens is a small, shaded park right on the Thames with a playground at its southern end. The river is right there. Big Ben is visible above the roofline. It’s the kind of quiet London moment that feels like a discovery even though it’s been here the whole time.

It’s also the last stop before you cross Chelsea Bridge into Battersea, so it makes a natural break — a chance to stretch legs and have a snack before the main event.

Battersea Park Children’s Zoo: sized exactly right for toddlers

Battersea Park Children’s Zoo doesn’t try to be London Zoo. It’s smaller, calmer, and almost perfectly calibrated for under-fives — meerkats, otters, monkeys, farm animals, a walk-through lemur enclosure, and a play area that could occupy a three-year-old for the rest of the afternoon on its own.

Pre-book online. Get there reasonably early. If you time it right for one of the keeper talks, the meerkats at feeding time are genuinely one of the better free shows in London.

Putt in the Park: pizza, mini golf and a playground in the same postcode

A five-minute ride further into the park brings you to Putt in the Park — one of those places that does several things well simultaneously, which is the only kind of place that works with a toddler in tow. The pizza is the real draw: proper wood-fired, made on site, the kind you’d travel across London for even without the mini golf. Eat outside, let the little one charge around the large playground right next door, order a second coffee. This is the lunch stop the day has been building towards.

The mini golf is 18 holes and takes about 35 minutes — good for slightly older kids if you have them along, or for adults who want to be competitive about something small and pointless on a sunny afternoon.

Albert Bridge: London’s most beautiful crossing

Built in 1873 and nicknamed “The Trembling Lady” — it was designed to flex slightly, which spooked people the first time they felt it move under them. Today it’s closed to motor traffic while structural repairs are underway, which means crossing it on a cargo bike feels almost illicit in the best way: just you, the Thames below, the candy-pink paintwork, and the view of the river snaking west towards Hammersmith.

Stop in the middle. Look both ways. It’s one of the better views London offers and it’s completely free.

The Diana Memorial Fountain: the wet bit we warned you about

An oval granite water channel set into the grass of Hyde Park, designed by landscape architect Kathryn Gustafson and opened in 2004. Water flows around the ring in both directions — calm on one side, faster and bubbling on the other — and children are actively encouraged to wade in.

This is not a fountain you look at. It’s one you get in. Your three-year-old will understand this immediately. Pack accordingly: a spare set of clothes, a dry bag for the wet ones, and some equanimity about the state of their shoes.

Open from 10am. Free. Gets busy on hot afternoons — go after lunch rather than at peak midday if you want space.

The Serpentine and the Albert Memorial: the long way home

From the fountain, the return leg follows the Serpentine lake east — flat, shaded in places, with birds to feed on the water and the extraordinary Albert Memorial rising from the treeline on your left. The Memorial is one of Victorian London’s great maximalist gestures: gold, enormous, covered in allegorical figures representing the continents, and somehow working completely. Worth five minutes of anyone’s afternoon.

The Serpentine Pavilion sits just beyond the gallery on the lake’s south bank — a new structure commissioned from a different architect every summer, always worth a look even if you don’t go inside.

That’s the loop done. Damp, fed, and thoroughly pleased with themselves.
