The only half term where you can reasonably expect nice weather, May half-term is a sort of last minute practice session before the beast that is the six-week school summer holidays. The (hopeful) nice weather is a big deal:  ‘go to the park’ or ‘day-trip to the seaside’ are viable options now when they most certainly aren’t in mid-February or late October. However, there are still many, many fun things to indoors in London itself for kids of all ages.

My name is Andrzej and I’m Time Out’s lead kids’ writer, and here’s my pick of the best things to do this May half-term. As ever, the idea with this list is to highlight the best new, returning or last chance to see shows; London also has plenty of evergreen fun for children of all ages, quite a lot of which you can find in out list of the 50 best things to do with kids in London.

What is it? This half-term marks your absolute last chance to see the OG Exploring Space gallery at the Science Museum: 39 years on from its opening in 1986, it’ll close for good on June 2.

Where is it? Science Museum.

How much is it? Free.

Why go? Exploring Space closing is not a bad thing in and of itself: it’s an old exhibition that opened considerably closer to the first Moon landings that the present day. It needs a refresh and it’s getting one. Nonetheless: it’s an icon and it’ll be sad to see it go; if you kids are fans or have never been, definitely sneak in this half-term for a last look.
