Fall in central and eastern Canada is a time of incredible beauty. As the weather turns cooler, the decidual forest goes through a spectacular metamorphosis, from vivid green to deep-red, orange and yellow. To catch the height of the fall colours, we start by exploring Algonquin Park on foot along scenic trails over bluffs and along cliffs. Then we switch to canoes on the countless lakes in the park. We paddle for five days into the park's more remote corners, keeping an eye out for moose, loons, otter and possibly wolves (we have a 50/50 chance of seeing them). We return to Toronto and take a side trip to Niagara Falls before flying to Winnipeg where we board the Churchill Express for a two-day ride through a wintry landscape to Hudson Bay. Along the freezing shores, polar bears await the colder weather to wander off on the ice. We wait along with them for two days, observing the great bears from the safety of custom tundra-buggies. The Hudson Bay lowlands have much more to offer than just bears. During day hikes (in which we carefully avoid direct encounters with polar bears) you'll get up close to unique arctic landscapes: lichen-clad forests of stunted spruce and extensive marshlands. We watch wildlife rarely seen from the buggies: arctic hare, arctic fox, caribou, and migrating birds. With the wind in your face, and crunching snow underfoot, you'll get a real taste of the arctic! Northern lights blaze across clear night skies to cap our days' outing. The trip is led by a multilingual wildlife biologist and is a treat for wildlife enthusiasts and photographers alike.
