Hormuz Island in Iran features a rare “blood rain” phenomenon where rainwater turns the beaches crimson red. The vivid coloration results from the high iron oxide content in the volcanic soil mixing with rainwater and seawater. The island contains 70 different colorful minerals, earning it the nickname “Rainbow Island.”
Nature’s Crimson Canvas
The remote Hormuz Island in the Persian Gulf has captured international attention after images revealed a startling transformation following recent rainfall. Heavy downpours turned the coastline blood red, creating scenes that appear almost otherworldly. This remarkable phenomenon occurs when rainwater interacts with the island’s unique soil composition, particularly its high concentration of iron oxide. The resulting crimson runoff flows toward the shoreline, creating dramatic red rivers that spill into the sea and temporarily transform the beach into what appears to be a scene from another planet.
Unlike many natural color phenomena that occur only during specific seasons, the “blood rain” effect on Hormuz Island can happen year-round whenever significant rainfall occurs. The island’s volcanic origins have created a landscape rich in minerals that contribute to this visual spectacle. When water activates these elements, particularly after dry periods, the resulting transformation showcases nature’s remarkable ability to create stunning displays through simple chemical reactions. The mineral-rich coastline continues to draw visitors from around the world who hope to witness this unusual sight firsthand.

The Rainbow Island’s Hidden Treasures
Hormuz Island’s reputation extends beyond its famous red beaches. Known locally as the “Rainbow Island,” this small landmass contains a remarkable variety of colorful minerals that paint its landscape in countless hues. According to official tourism sources, visitors can encounter up to 70 different colorful minerals while exploring the island. The changing soil colors create a natural mosaic that shifts as you traverse the terrain, offering new visual experiences with each step. Despite its extraordinary natural features, Hormuz remains largely undeveloped and sparsely populated, preserving its pristine condition for those willing to make the journey.

One of the island’s most fascinating resources is the iron-rich red soil locally known as “gelack.” This distinctive earth has significant industrial value and has been collected for various commercial purposes. However, what surprises many visitors is learning that the locals have incorporated this mineral-rich soil into their culinary traditions. The “gelack” is used in certain regional dishes, creating a unique gastronomic experience that connects directly to the island’s geological character. This practice demonstrates how thoroughly the island’s natural features have been integrated into local culture and identity.

A Natural Wonder Gaining Recognition
Recent videos of Hormuz Island’s blood rain phenomenon have gone viral across social media platforms, bringing new attention to this natural wonder. The footage shows rivulets of bright red water flowing across beaches and into the Persian Gulf, creating striking visual contrasts with the turquoise waters. International tourists increasingly seek out these unusual natural phenomena, making Hormuz a potential destination for those interested in geological wonders and unique landscapes. The island’s relative isolation has preserved its natural state, though increased tourism interest may eventually lead to more development.
While Hormuz Island’s blood rain is certainly distinctive, similar color-changing natural phenomena occur elsewhere around the world. Spain’s Torrevieja pink lake derives its color from bacteria and algae that thrive in its highly saline waters. In the United Kingdom, bioluminescent plankton occasionally create glowing blue shorelines at night, as witnessed at Sheerness Beach in Kent. These remarkable natural displays remind us of Earth’s capacity to create breathtaking visual experiences through ordinary biological and geological processes, offering moments of wonder in an increasingly developed world.
