10 Iconic Geothermal Hot Spring Designs

By Ecoist in Energy & Fuel, Geography & Travel, Home & Garden

Before the days of jetted tubs, spas, and heated pools, the only real place to soak in hot water not in
your bath tub was to visit a geothermal hot spring. Although not an option for some, you might be surprised to learn that you live closer to a hot spring than you think. In fact, there are hot springs on every continent produced by superheated groundwater pushed to the surface by the extreme heat from the Earth’s core. So pass on what is likely a coal-powered soak and visit one of these classic all-natural spring-fed soaks.

One of the most visited tourist destinations in Iceland, the Blue Lagoon or Bláa lónið is fed by the output of nearby Svartsengi geothermal power plant. Superheated water is vented from the ground as steam near a lava flow and used to spin turbines that generate electricity. After going through the turbines, the steam and hot water passes through a heat exchanger, providing heat for a municipal hot water. Then the water is fed into the lagoon at a very agreeable 104°F for recreational and medicinal users to bathe in.

Part of the Joshinetsu Kogen National Park, the “Jigokudani Monkey Park” is located in the valley of the Yokoyu-River and is the chosen home of more than 100 Japanese Macaques, Japan’s indigenous monkeys. The monkeys enjoy bathing especially during the cold winter months when temperatures drop below freezing and the valley is covered by a thick layer of snow. The monkeys are usually quite happy to share their little slice of heaven with human soakers.

Located in the City of Bath in southwest England, the springs at Bath were first discovered in 836 by the British king Bladud who built the first baths. After centuries of use, the water that flows through the Roman Baths are now considered unsafe for bathing, partly because the water passes through the original lead pipes. However, the nearby Thermae Bath Spa allows modern-day bathers to experience the waters via a series of more recently-drilled boreholes.

Nestled in a rocky canyon of southwestern Colorado, Ouray’s 250 foot public pool contains over a million gallons of crystal clear natural hot springs water, free from the strong smell of sulfur typical of many hot springs. If you visit Ouray, be sure to drink lots of water, as soaking in these baths 8,000 feet above sea level will quickly dehydrate flatlanders and contribute to altitude sickness.
