Last updated July 2026
Castor Bay Beach Reserve is a small neighbourhood reserve on Auckland’s North Shore that combines a modest playground with direct access to a sheltered swimming beach. The reserve sits at the beach end of The Esplanade between Milford and Campbells Bay and features climbing equipment, a wobbly bridge and interactive play toys on grassy areas shaded by mature trees. It functions best as part of a relaxed family outing that includes swimming and picnics rather than as a standalone destination park. Public toilets lie a short walk along The Esplanade, and the site offers boat ramps plus easy walkway access. The location is roughly 12–14 km from central Auckland, a drive of about 15 minutes under normal conditions.

About Castor Bay Beach Reserve
Castor Bay Beach Reserve occupies a compact grassy area directly beside the beach at the end of The Esplanade. The playground occupies one section of the reserve and includes climbing equipment, a wobbly bridge and interactive toys suitable for younger children. Mature trees provide shade over much of the grassed space, creating comfortable conditions for picnics during warmer months.
The adjacent beach is small and sheltered, making it particularly suitable for family swimming with younger children. The close proximity of the playground to the water allows easy movement between land-based play and swimming. Picnic tables and seating are provided within the reserve boundaries.
Access is available from the beach end of The Esplanade and via a walkway between numbers 75 and 77a Beach Road. Street parking is required, and spaces can be limited during peak times. The nearest public toilets sit a short walk along The Esplanade.
Swimming at Castor Bay Beach
The beach offers calm, sheltered waters ideal for supervised family swimming. No lifeguard service operates at this small reserve beach. Visitors should follow standard water safety practices, including checking conditions and supervising children at all times.
Boating and Boat Ramps
Two boat-launching options exist at the reserve. A boat ramp is located at the end of The Esplanade, while a dinghy ramp sits at the southern end of the reserve with access from Beach Road that includes steps. Limited parking is available nearby, and users should check tide and weather conditions before launching.
What’s Around Castor Bay
Castor Bay lies on the East Coast Bays between the suburbs of Milford to the south and Campbells Bay to the north. Neighbouring beach reserves in both Milford and Campbells Bay offer additional playground and swimming options. The area is characterised by its sequence of small, sheltered beaches and neighbourhood reserves connected by coastal roads and walkways.
What Visitors Often Say
Visitors describe the reserve as a quiet, family-friendly spot where children enjoy the playground and easy beach access. Many appreciate the shade from established trees and the convenience of combining play, swimming and picnics in one location.
Reviewers note the sheltered nature of the beach makes it suitable for younger children, though parking can be tight on busy days. The modest scale is seen as a positive for those seeking a low-key neighbourhood experience rather than a large destination park.
