Polar bears are not zoo animals, and a walrus could sink your kayak. Botswana's Makagaigadi Salt Pans, an area so flat and empty you can see the curvature of the Earth. It's not for everyone. The area, in the far north of Quebec, is 400 miles from the nearest town and has 22 hours of daylight in summer.
Stays are in traditional round canvas tents.
Polar bears are very nice, but they have to feed.
