25 of the World's Most Beautiful Beaches

14. Waipio Valley Beach, Big Island, Hawaii

Waipi'o (or Waipio) Valley, which is about one mile wide and six miles deep, is named after the river that runs through it (wai-pio means curved water in Hawaiian). The valley splits into many 'fingers' towards the back, each with its own waterfall. The valley meets the ocean to the north with a lovely black sand beach divide in two by the river.  Waipi'o Valley Beach on Hawaii's Big Island's north-east coast is a curved black sand beach surrounded by waterfalls and massive cliff faces. It's a little off the beaten path, but those who make the trip rave about the views and water.
