Kaihalulu’s sands are rich in iron, which gives the beach its
striking red colour. It is fairly hard to find, as it is
technically on private property. It is worth the trek if you can
make it, but be sure to bring good hiking shoes.

This ash-black beach has been created by volcanic activity on
the Big Island in Hawaii. The water can be pretty rocky and not
very pleasant to swim in, but is home to green turtles. As cute as
they may be, don’t disturb them because they are endangered.

This stunning beach in Fort Bragg off the northern coast of
California is covered in sea glass. Though beautiful, the glass
originates from years of rubbish dumping and has been smoothed by
water over time.

The mossy-green beach of Papakolea is a must-see. The green
color comes from the mineral olivine, which is lighter than the
other components of lava that make up this beach. While the water
is safe to swim in, surfing is not advised as the waves can get
pretty rough.

Sometimes referred to as the Sea of Stars, Vaadoo on the Raa
Atoll islands of the Maldives is famous for its bioluminescence,
which is light emitted from living organisms. The ‘stars’ are a
result of plankton that glow in the dark when shifted by the
waves.
