Much of Iceland is wild and inaccessible. The best (sometimes the only) way to see this dramatic country is by helicopter. Typically, tours circle dormant volcanic craters, land on immense glaciers and permit passengers to observe spectacular waterfalls and geothermal activity at close range. It is even possible to overfly the infamous Eyjafjallajökull volcano, whose eruption in 2010 became global news. The leading Icelandic company, Norðurflug, operates Eurocopter and Bell Jet Ranger helicopters that carry four to eight people and have maximum flying times of three hours.
