Cruise Prince Christian Sound, a beautiful fjord system that connects the Labrador and Irminger Seas. In Greenland, soak in the 100⁰ natural hot springs at Uunartoq, see polar bears in Nanortalik, cruise Tasermiut Fjord, and hike the trails out of Narsaq, an agricultural town rich in cowboy and Nordic history. In Newfoundland, experience one of North America’s oldest settlements at St. John’s and don’t miss Quidi Vidi, the village-within-a-city.
