Hot springs are a precious gift from nature to humanity. Since ancient times, hot springs around the world have been used as natural resources for wellness and spa treatments. The following five extraordinary hot springs in the world have taken on astonishing appearances due to their unique local geography, water quality, and climate environments.

1.Grand Prismatic Spring
Located in Yellowstone National Park, USA, the colorful pool known as the Grand Prismatic Spring—also called the Great Prism Hot Spring—is the largest hot spring in the U.S. and the third largest in the world. It spans 75–91 meters in width, reaches a depth of 49 meters, and discharges about 2,000 liters of 71°C hot water per minute. The Grand Prismatic Spring resembles a huge, deep blue eye hidden within the Earth’s misty veil, surrounded by radiant, vivid flames.

The color of the Grand Prismatic Spring’s surface changes with the seasons. In spring, the pool shifts from green to a brilliant orange-red, due to the varying ratios of chlorophyll and carotenoids in the algae and pigmented bacteria living in the mineral-rich waters, which fluctuate with the season. In summer, the chlorophyll content is relatively low, showing orange, red, or yellow hues. In winter, with less sunlight, these microbes produce more chlorophyll to suppress the colors of carotenoids, resulting in the water appearing deep green.

2.Blood Pond Hell
Beppu in Japan is home to the world’s second-largest geothermal hot spring system. Its vast and abundant hot spring ecology has earned it the nickname “hot spring theme park.” Among them, the blood-red hot spring shrouded in steam is the most breathtaking, resembling a scene from hell.

The blood-red Blood Pond Hell, shrouded in mist, looks like something out of a horror story. The scene of a pool filled with blood is right before your eyes. The blood-colored water in the pond comes from its rich content of sulfur, carbonic acid, and iron. Subjected to high temperatures and pressures beneath the Earth’s surface, a chemical reaction oxidizes the iron, which then erupts from underground and accumulates in the pool, forming its current appearance.
