A beach is not just the sea but the sand, rocks and plants around it. Some beaches have sand that squeaks like snow, some are pink or black, and on one the sand is replaced by glass polished by the waves. Here are beaches that appear on every list of the most beautiful, and where their colours come from.
Whitehaven (Australia). A beach about seven kilometres long on Whitsunday Island. The sand is almost pure silica, brilliant white and cool underfoot.
Navagio (Greece). Shipwreck Beach on Zakynthos: a cove among white cliffs with a rusting ship that ran aground in 1980. Because of rockfalls, access is restricted from time to time.
Pink Sands (Bahamas). The soft pink colour comes from the tiny shells of single-celled marine organisms called foraminifera.
Reynisfjara (Iceland). Black volcanic sand and basalt columns. It is very dangerous because of sudden large “sneaker” waves, so stay well back from the water.
Anse Source d’Argent (Seychelles). Sculpted granite boulders, turquoise water and palms make it one of the most photographed beaches in the world.
Glass Beach (California). Once a dump, the shore is now covered with colourful pebbles of wave-polished glass. Taking the glass is prohibited.
Beaches have their own flora too. On Mediterranean sand dunes the white sea daffodil (Pancratium maritimum) blooms in summer with a strong scent, and it is protected in many countries. Dune grasses and creepers bind the sand and protect the shore from erosion, so it is best to keep to paths when crossing dunes.
