Iceland

Sitting in the North Atlantic and hugging the Arctic Circle, Iceland is the northernmost nation on Earth. This land of glaciers, volcanoes and rugged coastline is a prime spot for eco-tourism. Thanks to the jet stream, Iceland is actually relatively warm, considering its near-Arctic location. Summertime trekking, ice climbing, glacier walking, wildlife tours, dog sled expeditions and trips to volcanoes are on the agenda for nature-minded visitors. Iceland is perfect for people who want to see unique, almost otherworldly, landscapes. However, one of its best attractions of this northern nation is actually located in the North Atlantic waters off Iceland's shores. Whale watching is possible year-round, with many boats leaving directly from the capital city of Reykjavik.
