Ruislip Lido's 40 acre lake is just the start of the fun. From miniature railways through to the 726 acre nature reserve surrounding the water, the London Borough of Hillingdon is lucky to have such an outdoor escape on its doorstep. There's even a beach, adventure playground and outdoor gym.
We visited during the popular summer months when splashing and sunbathing abounds, but it's open and has plenty to enjoy all year round.
