Mill Rd Playground

Honestly, a playground next to a castle with cows grazing nearby is a pretty hard setup to beat. The shade trees make a real difference on warm days, and there’s enough seating — benches, picnic tables, shaded spots — that parents can actually sit down properly rather than hovering awkwardly. It works well for a wide age range, so siblings aren’t fighting over whether the trip was worth it. Parking is easy enough that you won’t spend half the visit circling, which in Arundel is not always a given.
