Arundel gardens

The gardens that sit beside Arundel Castle are a proper treat if you're after a gentle wander rather than a serious hike. You're looking at manicured lawns sloping down towards the River Arun, with the castle itself looming overhead - it's the backdrop that makes the walk, frankly. In spring the rhododendrons are spectacular; by summer it's all about finding shade under the mature trees and watching the water. There's a circular route that takes maybe forty minutes at a leisurely pace, though you can knock it down to twenty if you're just cutting through.

Families with younger children will find it accessible enough - flat sections, proper paths, a few spots to sit and let them burn off energy. Older walkers will appreciate the lack of steep gradients and the views across the valley. History types might linger longer, given the castle connection, though the gardens themselves are more about peaceful strolling than narratives.

No idea on entry fees without visiting their website - Arundel's tourist office would sort you out. Allow an hour if you're stopping for photos and a breather. Best visited outside peak summer weekends when coach parties descend on the castle and clog things up. You're barely ten minutes from South Downs Caravan Park, which makes it a natural leg-stretcher between proper walking days in the park itself. Worth combining with a castle visit if that's your thing, but don't expect wilderness.
