Jerusalem Bay, Ku-ring-gai National Park, is a nice bay east of Cowan Station. The bay is popular with bushwalkers as it is part of the Great North Walk. The bay is sometimes known for an iconic photo of the single palm in front of the water. The bay itself is also popular with boaters who can anchor in the bay. Jerusalem Bay can be accessed by the Hawkesbury River and Broken Bay or from Brooklyn or Cowan Railway Stations.
