There are a lot of scenic coastal routes up this way. We were just up in Newfoundland , where we spent a week on the west coast, mainly in Gros Morne National Park That place is just stunning. We also went up to L'anse Aux Meadows, which is the site of the only Viking settlement in North America - preceding Christopher Columbus by about 500 years. Almost smoked a moose on the highway too...
Great trip!
