(5 Km.) Reykjavik: After walking around the shopping area of the capital, we go to the suburbs to visit the complex of the pearl. It is an edifice built on a hill, where there are exhibitions, lectures and on top of that there is a restaurant with magnificent views of the capital. It was built over the hot water tanks that provide the entire capital. This water is channeled from the central of geothermal Svartsengi, 45 km far, and from which the water loses only 2 degrees of temperature.

Reykjavik - Perlan

(31 Km.) Kleifarvatn: It is a lake located in an area with lots of geothermal activity. It lies within the nature reserve Reykjanesfólkvangur, much of which is formed by extensive lava fields. In the access road to the lake can see some of drying cod. It is a good area for trekking.

(49 Km.) Bláa Lonid (Blue Lagoon): Blue lagoon or blue lake is a natural ecosystem with geothermal waters, discovered by chance in the late seventies, are beneficial for psoriasis, and attract a growing mass of people. As ecosystem, the Blue Lagoon appears to be unique. The original element of this lake is the composition of thermal water: 2/3 of sea water and 1/3 of rainwater, while geothermal waters are typically composed entirely of storm water.

Bláa Lonid (Blue Lagoon)

The biology of the Blue Lagoon is simple: there are only a few species. You might think that the salinity, temperature and pH would be tolerated by most living organisms, but it seems that the combination of these factors, which must be added the heavy precipitation of silicon, to prevent Most organisms grow on it. We did not find more than a few species of microorganisms such as bacteria and green algae, but these species are present in large numbers. Green and white algae growth does not seem to be limited by the low concentrations of nutrients such as phosphates and the low concentration of nitrogen. Blue Lake water purufied itself and quickly destroys the contaminant bacterias brought by the bathers such as bacteria from skin or intestinal origin. The lake water is pumped by a geothermal station of production of water and electricity. This water, part of which is made up of filtered sea water is pumped over a thousand meters deep. Because of its high salt concentration, can not be used directly for heating. Therefore it is only used to heat water from the source before re-launch into the lake without being contaminated. Its temperature is about seventy degrees Centigrade and concentrations of salt is about the same as that of seawater. About a thousand tons of water reach to the lake every hour. This water is evacuated by infiltration in the lava of the soil. Silicate and algae are the main components of the mud that has helped many suffering from psoriasis. Its properties were discovered accidentally in the late seventies by an affected given that he liked hot baths in the lake. While there has been no scientific explanation until now, the Icelandic dermatologists have found excellent results in those with psoriasis who bathe in their waters for years.

(18 Km.) Njarðvík: Come to this population in which sleep the first night and from which we will go in the morning at the airport in Keflavík (7 km) to return the car and fly back to Barcelona.
