The sun is Strong so be prepared to slather on the sunblock and wear a hat if you can. We are always very good about wearing sunblock but one day at Watsons BAy even with sunblock we got a little pink; not burned but pink (this was with sunblock 100 for the face and 85 for the body). Thankfully my hat saved my face, ears and neck from turning pink.
There are signs posted in the park to be careful and watch your step. One wrong move and splash...your a statistic. There is actually 50 recorded suicides here a year.
In the Sydney Harbour National Park Gap Bluff there are no dogs allowed. I don't think anyone wants their pooch going over the edge and into the water below.
