Most people are familiar with pristine white sand beaches but many have yet to discover the magic of black sand - and when they do, they are usually left intrigued and amazed. It forms from eroded volcanic material such as lava, basalt rocks and other dark-colored rocks and minerals and is found on beaches near volcanic activity. The black sand on the ‘Island of the Gods’ originates from its most sacred volcano, the majestic Mount Agung. It is believed that black sand possesses healing powers, helping to treat arthritis, sciatica and other joint inflammation illnesses.
