The Blue Lagoon. Geothermal seawater.

Smells a wee bit like egg but is still amazing. -15 degrees above the water and toasting below. The water temperature is constantly changing so you have to follow the hot patches around!

When you come out of the water you need to get to your towels quick as the wind chill takes your breath. Thirty seconds of standing on the wooden deck and your feet feel like blocks of ice.

According to Wikipedia “In 2006, 26.5% of electricity generation in Iceland came from geothermal energy, 73.4% from hydro power, and 0.1% from fossil fuels.” Knowledge is the bomb.
