A ferry from Circular Quay is the most spectacular way to travel  to Watsons Bay. It is a beautiful little village, with the naval base, HMAS Watson located behind it.
 
From the ferry wharf, turn left along Marine Parade passing  Watsons Bay Beach Club, and Doyle's on the Beach restaurants. A laneway leads to Cove Street, and a left takes you along Pacific Street. Wandering  along  this street you will see many beautiful terrace houses and apartments. At Greens Point Reserve follow the track to Camp Cove Beach. At the eastern end of the beach the South Head Heritage Trail begins.
 
The trail passes the secluded Lady Bay Beach on the way to Hornby Keeper's Cottage which was completed in1860. Further along the track is Hornby Lighthouse, which operated from 1858. The light was powered initially with a high tech kerosene lamp, and became fully automated in 1933. Today it is powered with a quartz halogen lamp.
 
Follow the track back to Camp Cove, and walk along Cliff Street and Military Road to Gap Bluff. The Gap has  spectacular cliffs and ocean views, but tragically many people have taken their own lives here.
This walk is about 2 kilometres. From the Gap a trail runs along the top of the cliffs to Christison Park, a journey of 1.7 kilometres. Ferries travel regularly from Watsons Bay back to Circular Quay.
