Castle Cove is a suburb on the lower North Shore of Sydney, in the state of New South Wales, Australia. Castle Cove is located 11 km (6.8 mi) north of the Sydney central business district, in the local government area of the City of Willoughby. Castle Cove is situated on the western side of Middle Harbour.
Castle Cove is an upscale, residential suburb of large single-family homes in Sydney's Lower North Shore region. This is an extremely green neighborhood – more than half of its real estate is taken up by parkland, including Castle Cove Park, HD Robb Reserve, Willis Park, and the sprawling Explosive Reserve woodlands, which earned its name since it was once a buffer area for a munitions magazine in nearby Bantry Bay. The Reserve comes with its own private castle, Innisfallen, which was built in 1903 and has only had a couple owners since then.
This is an almost completely residential area – there is one small plaza with a couple restaurants, a coffee shop, a butcher, and baker. For more dining and shopping options you'll need to head to some nearby neighborhoods.
Castle Cove is bordered on the north by Roseville Chase and Middle Harbour, on the east by Middle Harbour and Sugarloaf Bay, on the south by Middle Cove, and on the west by Roseville.
