River Lee Country Park, between Cheshunt and Waltham Abbey, is home to a trail of different sculptures that offer an exciting type of walk through the park. With 16 sculptures to find, each one is a different style and material but they're fantastic and the kids will love trying to find them all. There's one that uses different woods of size and density to create a xylophone that can be jumped on, another that looks like a giant chair and one that shows two beetles on a large log.
