36: Visit a beach made entirely of shells (WA)

Dawdling along the sand, picking up shells from the seashore and carefully examining the hollow casings is a universal beachcombing activity. So where better to do it than the unimaginatively-but-appropriately-named Shell Beach in WA?

One of only two beaches of its kind in the world, Shell Beach is a brilliant white stretch of what at first looks like snow, but upon closer inspection is millions and millions of tiny white cockle shells. This particular type of cockle – the Cardiid – is hardy enough to withstand the unusually high salinity of the waters of L’Haridon Bight here in Shark Bay, and its predators are not. The result is this stunning natural phenomenon.
