The first is that if you take the ferry to Manly from Circular Quay in the dark, you can enjoy the beautiful and eerie sight of phosphorescent algae glowing green-blue in the wake of the ferry.
The second is the Steyne Hotel. Dodgy name, but a fantastic, busy place, about six bars in one, and a real landmark in Manly. Get upstairs and outside on the balcony.
