Iran's 'Edible' Red-Sand Island: Hormuz Transforms Crimson with Rain

• Hormuz Island in Iran's Strait of Hormuz is famous for its red-sand beaches that turn crimson during rainfall.
• Known as "Rainbow Island," its unique geology features high concentrations of iron oxide, particularly hematite.
• Rainfall washes iron particles from the hills, coloring the shoreline and seawater deep red, a dramatic contrast to the Persian Gulf's blue.
• The island's mineral-rich red soil, locally called "gelak," is used for pigments, cosmetics, and even in small quantities in local cuisine.
• This rare natural spectacle, especially in winter or early spring, attracts photographers and tourists despite the island's arid climate.
