Bobbin Head is apart of the beautiful Ku-ring Gai Chase National Park. Get in the zone and sit under the shade of the trees while watching the boats bob up and down with friends over a picnic. If you're feeling energetic go for a walk and explore the park. More than 350 Aboriginal sites are recorded in this protected area of coastal bush and beaches. There's a $12 park entry fee, but it's worth every penny to enjoy the magic of this place.
