Grab a book and head to Blues point reserve at McMahon's point. There is a beautiful grassy area with plenty of sunny spots (if you have a blanket) or some chairs in the shade where you can read in peace, enjoy the amazing view of the Harbour bridge, Opera House and Luna park without the bustle of the city.
Its the perfect balance of peace and quiet, without the feeling of being in the busiest part of Sydney combined with the beautiful views of the Iconic Sydney sights
