Yesterday we took another ferry ride  from kings warf    this ferry went up a river that had several stops  a great way to see some sights   we were hoping to get to Olympic park but was to far to walk from the ferry terminal
 If you are thinking of using the ferry system in Sydney check into getting a  opal card   this will help with the cost and is so much easier 

Also at kings warf prices for food and drinks are much better than circular quay
