Lammas Land Playground

If you’re in Cambridge with kids in tow, Lammas Land is genuinely one of the better options in the city. The paddling pool is the real draw in summer — it gets busy, but that’s because it’s actually good. There’s a solid climbing structure, swings, and slides that cover the toddler-to-older-kids range without feeling like an afterthought. The green space around it is generous enough that you can actually spread out a blanket and not feel like you’re on top of other families. Toilets on site too, which matters more than people admit.
