    Canada is a land filled with fascinating places and amazing adventures. The only problem: Narrowing down your choice of destinations. Here are several of the best places to visit in Canada for any traveler determined to discover the true north.

Churchill, Manitoba

Set on the shores of Hudson Bay, this subarctic（靠近北极的）town has earned international fame as the polar bear capital of the world. So plentiful are the bears that the town actually has a “polar bear prison,” which holds bears that are resistant to people's instruction and wander into town until they can be released back into the wild. Encountering a polar bear in the wild is no doubt an unforgettable experience.

Banff and Lake Louise, Alberta

Set inside the borders of the vast Banff National Park, Banff and Lake Louise is one of the best places to visit in Canada. Here you'll find a Rocky Mountain wonderland; a place of electric blue glacial lakes, waterfalls, and abundant wildlife (from elk to bighorn sheep). Stay either in Banff, the busy center of the area and home to classic hotels like the Fairmont Banff Springs (one of Canada's greatest hotels), or hike trails up into the mountains—and unparalleled(无与伦比的)silence-are just steps away.

Bay of Fundy, New Brunswick

Recently shortlisted in a massive international competition to name a new seven wonders of the natural world, the tides on this big bay, make it truly one of the best places to visit in Canada. The most extreme tides on earth, they rise and fall more than 50 feet in some places. These can be seen most dramatically at a place like Hopewell Rocks, unique stone formations that, at low tide, form towers on dry land but become islands as the water rises.

Quebec City

The oldest walled city in North America, Quebec City holds both British charm and culture alongside its unmistakable French-Canadian character. It also bears the distinction of being the place where, as every good Canadian history student knows, Wolfe defeated Montcalm on the Plains of Abraham, securing Canada for the British Empire.
