Less than 3 hour activity. From Darling Harbour, take a scenic ferry ride to Watsons Bay, and begin your walk along the ocean cliffs. You'll arrive at Sydney Harbour National Park, Hornsby Lighthouse. As you approach the lighthouse, the trail offers breathtaking views of Sydney Harbour, the Pacific Ocean, and even many photo opportunities of the Sydney skyline in the distance. Built in 1858, Hornsby Lighthouse holds a special place in Australian history. Its construction was prompted by the tragic sinking of the Dunbar in 1857, a maritime disaster that highlighted the need for improved navigational aids around Sydney's rugged coastlines. Painted in distinctive red and white stripes. Perfect short activity from Darling Harbour. read more
