They call hot springs mineral waters rising from the ground with more than 5 ° C surface temperature. These waters come from underground layers of earth found at higher temperatures, which are rich in different mineral components and allow their use in therapy as baths, inhalations, irrigation, and heating. Usually found along fault lines as along the fault plane can be introduced groundwater warming at a certain depth and then rise as vapor (which may condense to reach the surface forming a geyser) or hot water. The hot springs are places surrounded by two major factors, one is the tranquilad and the other is relaxation. In the world there are hot springs which are the centers of attention for tourists and locals.
From the southernmost part of the continent in Chile, to the other end of the land in New Zealand, that is, the 5 most amazing and impressive thermal Planet.
- Termas Geometric in Chile. Naturally discharged into a stream of half a kilometer long in the middle of native forests of the Villarrica Volcano National Park in Chile. There are approximately 17 rock pools in which hot water at an ideal temperature is collected, toilets and lockers near each pool, and a barbecue to eat sanduich, drinks, tea, coffee, hot chocolate, spring water with lemon and cucumber .
The thermal waters of Termas Geometric present a moderate temperature (45 ° C) to high (89 ° C) and a moderately alkaline pH. Due to its high content of Ca they are moderately hard and low alkaline water.
For their sodium content, chlorides and sulfates are water-chlorinated-sodium sulfated.
- Blue Lagoon in Iceland. A young, still forming, and geology rich in volcanoes, glaciers, gorges, lava flows, cliffs, craters and waterfalls land. The geothermal water is abundant in the country, offering its inhabitants and travelers great opportunities to test their benefits.
- Pamukkale in Turkey.

The tectonic movements that took place in the fault depression of the Menderes River Basin not only caused frequent earthquakes but also led to the emergence of numerous hot springs. Were those waters, with its high mineral content – chalk in particular – that created Pamukkale. Among the most ancient rocks can be found crystalline marble, quartzite and schist, dating from the Pliocene period, while the top layer is the Quaternary. The latest deposits of calcium carbonate give the place a dazzling white appearance. These sources, well known in ancient times, were described by the Roman architect Vitruvius. The Phrygian Greeks attributed to their therapeutic waters, granted by the gods, especially Asklepios (demigod of medicine) and his daughter Hygieia (Goddess of health, hygiene and healing), under the protection of Apollo (god of medicine and healing).

Called bloody baths, because they have a reddish color is striking, but this color is given by the high amount of iron contained in these warm waters. The bloody baths, have a slope of 130,000 kiloliters of hot springs that come from inside the earth, to get an idea, with this amount of water would fill 3,600 swimming pools 25 meters long.
