A range of approaches are used for close-range bear watching in the northern hemisphere. Some guides are prepared to lead clients on foot to watch bears at close range Elsewhere, for example, in parts of Alaska and Kamchatka, there are raised viewing platforms next to rivers where brown bears congregate to feed on salmon at particular times of year. These are open wooden structures and the bears almost certainly could, if they wished, climb or destroy them, but they have no reason to do so since fish are plentiful. Similarly, it is possible to watch brown bear at very close rage from an inflatable dinghy in the Khutzeymateen Inlet in northern British Columbia, Canada, because the dinghy drier knows the individual bears well and keeps the boat at a sufficient distance that it could outspend the bears if they should, in fact, turn aggressive. In searching for polar in and around Svalbard north of Norway, however, guides will typically keep inflatables at a greater distance since polar bears can swim extremely well and may indeed see humans as potential prey. In watching black bear from sea kayaks in Southern Alaska, in contrast, the minimum approach distance is set by the bears, which run away if the kayaks approach too closely. Finally to watch polar bear at Churchill on Canada’s Hudson Bay, where the bears are extremely hungry as they gather to wait for the sea ice to from, tourists must be physically protected from attack either inside giant tundra buggies where the windows are too high for bears to reach, or inside a caged lodge where bears are unable to push their way between the bars to get at the tourists inside.
