The main swimming beach in Broome is the famous Cable Beach, which is white sand and clear waters.
The northern end of the beach offers 4WD access, and hosts a small nudist section. Sunset is marvelous here, although on a full moon head to Town Beach where you may be able to see Broome's 'Staircase to the Moon' (which is the refection of the moon on the mud flats). It is a fabulous sight, and well worth seeing.
At the end of Cable Beach is Gantheaume Point, where there are some fabulous looking cliffs. There are also some dinosaur footprints, set within the cliffs which you may be able to see. Also on Gantheaume Point is a lovely rock pool called Anastasia's Pool.
