Pukaskwa is known as a destination of unsurpassed beauty on the largest freshwater lake in the world. The park also contains many inland lakes and wetlands connected by streams that flow into the major rivers that, in turn, drain into Lake Superior. The White and Pukaskwa Rivers are the largest rivers in the park. Inland lakes support various communities of native fish including brook trout, yellow perch, northern pike, walleye, and white sucker. Waterfalls present along the coast have naturally prevented the spread of many non-native fish species from entering inland waters.
