Iceland: Blue Lagoon (Revisited)

The  world-famous Blue Lagoon! Blue Lagoon is a hot spring spa that is iconic and often a symbol of Iceland – milky blue steaming pools of healing water set against the backdrop of black lava. High silica content renders water milky blue color and complex of pools, waterfalls, mud baths, and natural steam vents make this the most visited attraction in Iceland. In actuality, it’s the water dumped by the nearby geothermal plant that makes these pools – the water is used to cool the turbines and then it is dumped in the nearby lava field where it seeps through the porous black lava rocks. The silica content is so high that it eventually clogs the rocks and forms pools. So Blue Lagoon is constantly growing. It’s close to the International Airport so makes for a very nice last stop before boarding a plane out….
