Unofficial. See review below where it says there is a sign saying nudity is no longer allowed on this beach.
To get to Saunders Beach head north along the Bruce Highway toward Ingham for approximately 25 km. About 200 metres after passing under a railway viaduct turn right and follow this road for about 8 km. This will take you into the small seaside settlement of Saunders Beach. When you reach the waterfront turn right into Reef Street and then bear right again after approximately 100 metres into Cay Street and continue to the end of it. When on the beach head south until you cross over the mouth of a small creek. It is a beautiful sandy beach with shady trees. Be careful crossing the creek at high tide, although it is never very deep.
