I live in Manly so get the privilege of riding the ferry all the time. But for those visiting Sydney - it's a must do! The views are amazing. Manly is also a great place to stay if you like the quiet life while still having cafes, bars on your doorstep (as well as all the lovely beaches) and still only 30mins from the city. Take a trip at night to see the harbour bridge and harbour in lights. Awesome!
