For the kids...
Bowood House and Gardens is near Calne, and offers an adventure playground for kids and a good day out for adults. Longleat Safari Park (including Centre Parcs) is less than an hour away, and makes a brilliant day out for families. Littlecote, near Hungerford, is also well worth a visit, especially when the jousting is on in the Summer.
Younger children generally just enjoy running up and rolling down the earthworks of Avebury and chasing the lambs.
Teacher's Cottage has a selection of leaflets about the many other attractions of the area.
