About Castor Bay
Castor Bay is a quiet North Shore coastal suburb on the East Coast Bays — between busier Milford and Campbells Bay, with a smaller residential population and a sheltered family beach as its standout feature. The residential streets climb from the bay up to the surrounding clifftops, with mature gardens and a mix of older bungalows and more recent renovations giving the suburb a relaxed established character.
Castor Bay Beach and Kennedy Park
Castor Bay Beach is a small sheltered sand cove between rocky headlands — quieter than the busier East Coast Bays beaches, with summer family swimming and good rockpool exploration at low tide. Kennedy Park at the southern headland is a small clifftop reserve with picnic spaces and panoramic Hauraki Gulf views back to Rangitoto, Auckland city skyline and Takapuna foreshore. The combination of beach plus clifftop park is the suburb’s defining recreational asset.
Quiet Coastal Character
Castor Bay’s smaller scale and quieter atmosphere distinguishes it from the busier East Coast Bays — fewer through-traffic streets, less commercial activity (the small village strip is genuinely small), and a sense of being “off the beaten track” despite being on the main East Coast Bays road. The local primary school (Castor Bay School) anchors the family demographic that defines the area.
