3. Greenland

Greenland has the ultimate capacity to surprise. Not the place to visit in the depths of winter, in summer the island is pleasantly green and, in some places, actually floral, while still being dominated by mountains, glaciers and ice shelves. The landscape is stark but that’s part of its charm. There are few people and even fewer roads, so getting around is all part of the eco-friendly adventures to be had in Greenland. Take to the kayak, dog sled or bush plane to explore glorious coastlines to see whales, seals and walrus, or head inland to the plateaus and plains to see reindeer, polar bear (don’t get too close) and oxen. This is a land where nature still rules – but the people are more than friendly and welcoming.
