Iceland - Iceland with Blue Lagoon

The Blue Lagoon began as a pool of wastewater from the Svartsengi geothermal plant in 1976. Few Icelanders, if any, had any desire to bathe in it, as the idea of bathing in wastewater from any kind of power plant was considered crazy.
The Blue Lagoon in Iceland is a modern wonder of the world tucked away in a jet-black lava field. The geothermally heated waters of this famous spa are renowned for their skin healing properties. Wispy plumes of steam rise off its milky-blue waters as mountains tower on the horizon, giving it a supernatural feeling. If you visit in winter, you might be able to enjoy the flickering colors of the Northern Lights above you as you replenish your body and soul.
This all changed in 1981 when an employee of the plant called Valur Margeirsson asked for permission to bathe in the pool. He had a skin condition, known as psoriasis which prevented him from bathing in Iceland's famous hot springs with others. Initially, he was met with resistance, and it seems very unlikely that he would have been allowed to do it today, but he kept asking his bosses and was eventually given permission to bathe in the pool.
The Blue Lagoon is Iceland’s most popular tourist attraction – meaning that it’s busy throughout the year. It’s busiest between May and September, with numbers peaking in July and August. It’s much quieter in winter, with December and January tending to be much less busy. The Blue Lagoon is generally more packed in the morning, between 10:00 and 2:00 p.m. (14:00). By 3-4 p.m. (15:00-16:00) the crowds have usually cleared out. The lagoon stays open until 10 p.m. (22:00) in winter and 11 p.m. (23:00) in summer, leaving plenty of time for a peaceful soak.
