Little Diggers Beach is on the northern outskirts of Coffs Harbour, and over the last twelve years or so has become the main unofficial clothes optional beach in the area. Well aware of its existence the local authorities have adopted the view that so long as nothing untoward happens it will be a case of live and let live.
Samurai Beach is 1 km in length with rocky outcrops at either end. It is very natural and beautiful, and ideal for fishing, snorkeling etc. The clothes optional area includes the entire length of the beach.
I've been to dozens of nude beaches in Australia and this is by far and away my favorite. It has beautiful scenery, amazing crystal clear water. Lovely golden sand and far enough away from the road to avoid kids and crowds.
