Set off on a bus tour to the best of historic Quebec and then venture outside the city to visit a thundering waterfall. Drive to the site of New France, the first settlement in Quebec. Pass the oldest Catholic Church in North America and, of course, make your way to Chateau Frontenac and stroll along Dufferin Terrace, a romantic boardwalk overlooking the St. Lawrence River. Then, head to Montmorency Falls and stand before a roaring cascade that's 1.5 times higher than Niagara Falls.
