The province of Ontario lies in southeastern Canada, between the open plains of Manitoba to the east and the soaring peaks of Quebec to the west. Canada's most populated province, Ontario is home to the vibrant cities of Ottawa and Toronto. Visitors can explore points of interest easily on a hop-on hop-off bus tour, such as the Canadian Museum of History, Notre Dame Basilica, Parliament Hill, and the Royal Ontario Museum. And, in true Canadian style, the open wilderness is never far away. Take a private or small-group tour—summer or winter—to discover pristine forests, shimmering lakes, and deep valleys. Many travelers come to admire the cascading waters of Niagara Falls (by sea or air), but Ontario also plays host to a number of natural attractions worth your attention. Delve into Algonquin Park (home to native bears, beavers, eagles, and moose) on a 3-day canoe tour. For something even more adventurous, take to the Ottawa River on a white-water rafting adventure. Fly over Thousand Islands on a helicopter tour for a bird's-eye view of Boldt Castle and the St. Lawrence River; or casually stroll among the vineyards at Niagara-on-the-Lake, where pinot noir and merlot grapes thrive. In the winter months, enjoy high-octane thrills on the snow and ice in Ontario's Georgian Bay.
