Balmoral sits in Hunters Bay, just outside the entrance to Middle Harbour — which makes it the first proper beach you reach after leaving The Spit. Twenty minutes, no open water to cross, and you are there.
That short run is what makes Balmoral the best first trip for anyone who has never driven a boat. There is nothing technical about it and you are never far from shelter, so you can spend the time enjoying it rather than concentrating.
It also means a three-hour hire is genuinely three hours at the beach rather than three hours of travelling. If you want to push on afterwards, Manly is another twenty minutes further around.
