Castle Cove suburb profile

Castle Cove is a quiet harbourside suburb on Sydney's Lower North Shore, set around the sheltered waters of Middle Harbour. The area is predominantly residential, with leafy streets, generous blocks and a mix of mid-century houses and contemporary renovations, many properties enjoying water views or easy foreshore access. It attracts families and professionals who favour a relaxed lifestyle of boating, bushwalking and parks rather than urban bustle. There is little in the way of a major shopping strip inside the suburb, so daily needs and services are often found in neighbouring precincts, with regular road and bus connections to the city and surrounding areas.
