There are plenty of lovely spots for picnics in Nelson, and especially at Saxton Field. Whether you're after a shady spot under a tree, a spot close to the kids playground, or somewhere to watch the ducks splash about in Orphanage Stream.
There are toilets in the Football Pavilion, and at Avery Field (near Saxton Road).
Find a place on the green field or a shady spot under a tree.
