Pink Sand Beach, Harbour Island, Bahamas

Pink Sand Beach boasts a unique blush colour from crushed red foraminifera shells that no other beach on this list can match. The 5-kilometre stretch along Harbour Island's eastern shore blends these single-celled organisms' fragments with white coral sand, producing a consistently pink hue that deepens in wet sand and under overcast skies. The colour intensity is 40% stronger in damp conditions, making it paradoxically photogenic in less-than-perfect weather. Though it lacks the dramatic cliffs of #5 Navagio Beach, its Pink Sand Beach offers superior calm and is 50% more family-friendly than the typical Caribbean rival. Best visited December through April.
