Wrapped around Farm Cove just steps from the Opera House, the Royal Botanic Garden is the loveliest free escape in central Sydney. Thirty hectares of lawns, rainforest pockets and harbour lookouts make it a favourite for picnics and slow morning walks. Follow the shoreline path for uninterrupted views back to the bridge and the sails. Bring a rug and something to eat, and time your visit for the golden hour when the light on the water is at its best and the crowds have thinned.
