Mile End Park Leisure Centre and Stadium

If you’ve got a toddler and it’s doing that classic grey London drizzle thing, Mile End Park Leisure Centre is genuinely worth knowing about. The soft play keeps the under-5s busy with a ball pit and a multi-storey slide — nothing too overwhelming for little ones, which is actually a bonus. There’s also a pool and a gym on site, so it’s easy to make a full outing of it while still being useful for the adults. Parking and loos are sorted, which matters more than people admit when you’re wrangling small kids.
