Hatchmere lake near Delamere Forest has the rare distinction of being a place where swimmers’ rights are recognised. There’s a small lawned area just at the roadside and a tiny sandy beach. On the scorching day we visited, there was a bit of algae on the lake, but it was fine for swimming. The water deepens gradually, so it’s good for kids. Conveniently, there’s a great-looking pub with outdoor seating, The Carriers Inn, just next to the lake access, so you don’t even need to pack a picnic.
