National Geographic Explorer follows in the wake of Eric the Red, from Iceland across the Denmark Strait to Greenland. While Iceland’s volcanic landscape is the world’s youngest and most dynamic, the rocks of Greenland are the oldest yet discovered on the planet. Southern Greenland has a dramatic coast with few inhabitants, innumerable fjords cut between the towering mountains and glaciers tumbling down from the gigantic icecap. Each new landing will present opportunities for discovery: hikes on the wild tundra, Zodiac or kayak forays amid icebergs and marine mammal sightings (we’ll search for the blue whales which frequent these waters.) And we explore Greenland’s ancient past: seeing the famous 15th-century Qilakitsoq mummies at the Nuuk National Museum, and walking amid two of the most important historical sites on the Viking trail. An optional extension in Iceland is available.
