Priceless London Wonderground, South Bank
Among the cabaret, circus shows, collection of preserved freak animals and other Coney Island-style attractions at the South Bank's Priceless London Wonderground is a terrifyingly high-spinning swing ride, the Star Flyer, the tallest travelling ride in the country at 60 metres, offering amazing views (tickets ?7, minimum height 1.2 metres). Or see children's shows such as Handa's Surprise, a theatre production of a tale set in Kenya (17-26 August, ?7.50), and Hairy Maclary (3-6 September, ?10).

Fountains, pools and lidos are great places to head with kids on hot days. London-baby.com has a brilliant list, including Kensington Memorial Park, with fountains, a sandpit and climbing frames; Diana, Princess of Wales Memorial Playground at Kensington Gardens, with water play area, musical instruments and sandpits, Duke of York Square in Chelsea, and the V&A museum courtyard paddling pool.
Fun creative activities led by artist Polly Brannan take place every Sunday for families at the galleries, where you can also see strange robotic sculptures by Bruce Lacey, and visit the cafe, bookshop and gardens. Most of their kids' short summer holiday art courses have sold out so this is a great chance to work with proper artists.
