We walk along the Arun river from Arundel to the Amberley bridge then along the other side of the river into Arundel Park Estate. In the estate we have a steep ascent and descent to the folly and back to the car park through the town where there are plenty opportunities for drinks etc. There are a few styles, one , mud and some paths are overgrown, but passable with care. Boots, long trousers and poles would be useful.
Picnic lunch and snack yes
Dogs on leads as there will possibly be cows and sheep
