Watsons bay is located at the northern end of the Eastern Suburbs. The cheapest and easiest way to get to Watsons bay is via ferry from Qircular Quay or Manly Wharf.
Once you arrive at Watsons bay I suggest going and having a quick look at the Gap Lookout and walking around some of the bush/ lookout trails on the ocean side. My personal favourite place to get lunch is at the Doyles fish and chips take away restaurant located on the Watsons Bay wharf. (Don’t go into Doyles restaurant if you’re on a budget. It cost a bit more to sit down inside). Fish and chips from the take away area on the wharf cost approx $13.80. After you eat its hard to turn down a swim so make sure you pack swim ware. Getting the ferry home is just as easy.
