The Hengill/Nesjavellir area in South Iceland is an outdoor sports paradise, with a variety of 160 km of marked and challenging hiking and biking trails in a region of high-temperature geothermal areas, hot springs, volcanic craters, lava fields, rivers and lakes. Besides hiking and mountain biking, you can also go fishing on Lake Þingvallavatn (Iceland's largest lake), visit Þingvellir National Park, tour the Hengill geothermal power plant and go horseback riding (price of activities not included in our tours).

Famous for a geothermal power station Nesjavellire every year, thousands of visitors are received at Nesjavellir for the purpose of educating them about the operation. The excellent reception hall offers an excellent opportunity to get acquainted with this technical and engineering achievement.
Because of the special geological situation in Iceland with the high concentration of volcanoes, geothermal energy is very often used for heating and production of electricity. The energy comes rather cheap. So in the wintertime, some sidewalks in Reykjavík and Akureyri are heated and on the road between Reykjavík and the International Airport at Keflavík (40 km long), the lights on the lamp posts are on the whole night.

In Iceland, there are three major geothermal power plants which produce about 17% (2004) of the country's electricity. In addition, geothermal heating meets the heating and hot water requirements for around 87% of the nations' housing.
