Cell Block B - 11 Bridge Street - Brooklyn. Stay in the gorgeous restored Brooklyn jail. Just 60 minutes from Sydneys Central Station, with Hawkesbury Rivers old railway station just minutes from your door. Cruise the river on a houseboat, or take an escorted river tour instead. Take Australia's last riverboat postal ferry to Dangar Island, a water-access only community. Trek the renowned Great Northern Walk, or go fishing in Parsley Bay. Kayak to Dead Horse Beach, or dine on the delicious local oysters and prawns. A stay on the Hawkesbury River is a gift for the soul.
