Much of the national park, part of the Hudson Bay and James Bay lowlands, is a flat plain covered by an extensive layer of peat; a layer of permafrost lies underneath. The treeless tundra consists mainly of wetlands—lakes, streams, bogs and rivers.
Polar bears congregate in the northern part of the park near Churchill around October, as they wait for freezing weather and the time when they can return to the ice in search of seals, their main food. The females dig their dens, and their young are born in late November and in December. The area around Churchill is one of the world's best places for viewing polar bears in their native habitat. Specialized tundra vehicles take visitors for close-up encounters.
The park, along a migratory flyway, also is a popular spring and fall feeding spot for waterfowl and shorebirds, including such rare species as the king eider, Ross' gull and gyrfalcon. Many build their nests here on the coast of Hudson Bay during the summer.
Churchill, in a somewhat remote location in northern Manitoba, can be reached by air and rail from Winnipeg. Since Wapusk is a wilderness park, it has no roads or trails. In order to visit the park, it is necessary to be part of an organized tour group, and several commercial operators provide tours into the park by plane or helicopter.
