The children can have a great time playing at the playground games while adults have a nice coffee at the cafe near by or throw a barbeque at the public barbeque facilities. After that the whole family can enjoy a nice walk along the arches of the viaduct. 

The barbeque facilities are really popular especially during warm days so you should keep that in mind before organising your day.

There are public toilets onspots as well as baby changing facilities.
