Time Out says
Watch the sunset at the foot of this beaut' tower
This red-and-white striped beauty is arguably the most adorable lighthouse in Sydney’s collection. Its bright colours and visible lantern give it a touch of carnival mischief, and make it well worth the stroll from Watsons Bay ferry terminal on the South Head Heritage Trail. It almost resembles something made by the hand of Willy Wonka, but the lighthouse and the nearby lightkeeper’s cottage dates back to 1858. This South Head location is a prime whale spotting vantagepoint, and the walk from Camp Cove will take you past plenty of cool pit stops, from historic gun emplacements to Lady Bay Beach, one of Sydney’s few official nudist bathing spots.
Getting there from the CBD: The easiest and most scenic option is to take the ferry from Circular Quay to Watsons Bay Wharf and amble along the cobblestone paths for the 20-minute stroll to the light.
