The hills surrounding Pfeiffer Beach in Big Sur, California, are rich in Manganese Garnet. A result of this being washed down onto the beach is the colour scheme you can see above - the entire stretch of sand has become a shifting, pink and purple canvas. Although it's probably inedible, I can't help picturing a bowl of Raspberry Ripple ice-cream every time I see it.
Kaihalulu

You won't find many beaches elsewhere in the world with sand as red as this one. Kaihalulu, or Red Sand Beach, is situated on the island of Maui and can thank the neighbouring cindercone hill for its intensely deep red appearance.
