Castor Bay is a small sheltered beach between Milford and Campbells Bay on Auckland’s North Shore, with a beachside playground at the Castor Bay Beach Reserve — climbing equipment, a wobbly bridge and interactive play toys on grassy reserve land shaded by mature pōhutukawa trees. The reserve sits at the beach end of The Esplanade and is the kind of small neighbourhood playground that pairs naturally with a swim and a picnic rather than functioning as a destination park. Public toilets are within easy walking distance along The Esplanade. About 15 minutes from central Auckland.

About the Reserve
Castor Bay Beach Reserve is a small grassy reserve at the beach end of The Esplanade. The playground itself is modest in size — climbing equipment, a wobbly bridge and interactive play toys — and is best thought of as the play component of a beach visit rather than a standalone destination playground. The reserve is shaded by mature pōhutukawa trees, which makes it a comfortable summer picnic spot.
The beach is sheltered and small — well-suited to swimming with younger children — and the proximity of the playground to the beach itself means kids can move easily between water and land play. Picnic tables and seating are provided inside the reserve. The nearest public toilets are within walking distance along The Esplanade.
