Verulamium Museum is situated in Verulamium Park, it has a large carpark outside but in the summer be warned you'll be lucky to get a space. The museum itself is entirely on one level which made it brilliant for our buggy and the friendly helpful staff gave us a selection of activity sheets which kept the toddler happy. We loved looking at the skeletons and the mosaics. the shop is bright and has lots of the usual pocket money gifts. Not a whole day of activity, rather a few hours but outside the museum there's a lovely park and a rather nice cafe. Well worth a visit if you are in the area.
