Blue Lake Hot Spring is the world's top health resort.

Iceland's Blue Lagoon geothermal hot spring is located in the southwest of Iceland, about 39 kilometers away from the capital Reykjavik, and it is one of the largest tourist attractions in Iceland. The Blue Lagoon is located in one of the areas with the most frequent underground magmatic activities on the earth. It heats the Blue Lagoon and makes the water transpiration. The steam heated by the lava flow near the ground is used to drive the turbine to generate electricity, and the steam passing through the turbine becomes hot water, and then the heat exchanger provides heat for the municipal hot water heating system. The average water temperature in the blue lagoon for bathing and swimming is about 40℃, and the water body is rich in minerals, such as silicon and sulfur. Soaking in the hot springs of the blue lagoon can help treat some skin diseases, such as psoriasis.

In winter, it is surrounded by ice and snow, and the lake is steaming. Minerals in water have special effects on skin diseases, and also have a good effect on difficult diseases such as psoriasis. Because it is not far from Reykjavik Kevlavik International Yang Chang, many tourists passing through Reykjavik take a bus to the Blue Lagoon to take advantage of their free time during the transit. Soaking in hot and humid water and rubbing with white carbon dioxide mud will sweep away the fatigue of the journey. Although the blue lagoon is open-air, it can receive tourists all year round because of its hot springs.

The blue lagoon seems to be the most typical photo of Iceland, and many people will soak in the light blue hot springs. After leaving the airport, the geographical landscape began to change obviously, and small fishing villages occasionally appeared near coastal roads. After entering the inland, both sides of the road are more desolate, and the endless volcanic lava is covered with moss, just like a soft carpet on the ground. The blue lagoon is a world-famous open-air hot spring. Even in the winter when snowflakes are flying, the lake is still full of hot air and smoke. Being in it, I feel as if I were immersed in a foggy world.
