Rainbow Cave

The cave was formed by water flowing toward the sea and passing beneath a salt mountain. The Rainbow Cave is about 30 to 40 meters deep. In some parts of the cave you can see numerous passages, which according to geologists were carved by water. The height of the ceiling varies along the cave, and in some places you need to bend your head to get through. Inside the cave, sedimentary and salt rocks lie in layers on top of one another, forming a smooth surface like the arc of a rainbow. The most beautiful part of the cave is its far end, where the colors reach their peak. The cave shows a spectrum of about seventy shades.

The Rainbow Cave is often confused with the Rainbow Valley. The Rainbow Valley is between 30 and 40 meters deep. It lies near the Rainbow Cave and consists of tall mountains made of colored soils. The colors of this cave come from the compounds and minerals it contains. The rocks have combined with metals such as iron, which has produced colored minerals.

One of the interesting facts about this sight is that the cave changes color every year. Each summer, as humidity inside the cave rises, the materials in it are affected by the heat and become glossier as they absorb moisture, and their range of colors changes. If you visit the cave in the hot summer season, be careful not to touch or lean on its walls, because the walls are wet and easily damaged, and the slightest contact may ruin them. It is also recommended that you not speak loudly during your visit and avoid making any noise, because the salty structure of these sedimentary rocks is so delicate that sound waves can even make them crumble.

To reach the Rainbow Cave, it is recommended that you ask the local people living on the island for help. If you head from the residential area of Hormuz toward Silver and Red Island, after passing these shores you reach the cave entrance by taking the second side road. The cave is located inside a valley, so its mouth is hard to spot. After a 15-minute walk you will reach the cave entrance.
