Great Tours: Iceland

Iceland was born from volcanoes erupting in the ocean roughly 25 million years ago-and its story continues to be shaped by them. Explore how the various types of volcanoes, active volcanic zones, history of eruptions, and the continued expansion of the mid-Atlantic ridge make Iceland a geologically active region like few others on our planet.

Beyond capturing the hearts and minds of photographers, geologists, and mountaineers, Iceland's glaciers are deeply rooted in the country's culture and history. First, look backward in time to learn how Iceland came to have so much, well, ice. Then, plunge into a world of ice tunnels, ice caves, and other extreme features.

The waters hugging Iceland's coasts play an important role in the country's culture and economy. Investigate some of the many lakes, rivers, lagoons, waterfalls, hot springs, and geysers to be found. Among them are the Jökulsárlón glacial lagoon; Gullfoss, the most visited waterfall in the country; and the thriving business of the Blue Lagoon.

Travel back in time to the cultural birth of Iceland, which began with the arrival of the first humans. Where did these people come from? What ancient documents help scholars understand early Icelandic settlements, and how do modern tools corroborate these sources? And another thing: What happened to all the Icelandic sheepdogs?

Iceland represents a great example of how, when humans arrive at a new place where none presumably lived before, their footprint is large-and often destructive. Follow along as early Nordic settlers grow grains and cereals, then turn to sheep farming. Also, explore the impact of early settlers on the extinction of the Icelandic walrus.
