Lake Superior Provincial Park, Ontario, Canada


This park on the spectacular eastern shore of Lake Superior protects about 1600 km2 of forest, bogs, shore and some islands.


The forests in different parts of the park differ considerably. The park lies in the transition zone between the temperate deciduous and the boreal forests. Temperate species like Opens internal link in current windowAcer saccharum (sugar maple) and Opens internal link in current windowBetula alleghaniensis (yellow birch) dominate in the south and boreal species Opens internal link in current windowPicea glauca (white spruce), Opens internal link in current windowAbies balsamea (balsam fir), Opens internal link in current windowBetula papyrifera (paper birch) and Opens internal link in current windowPopulus tremuloides (quaking aspen) in the north1. Most of the former forest type in the park was logged, either before or after the park was created – logging there ended in 1992, 48 years after its creation – while a larger portion of the boreal forests has survived untouched2. In the northwest, there are “boreal rainforests” near Lake Superior (see Opens internal link in current windowMichipicoten parks).


Highway 17 runs through the park. There are many hiking trails starting from the highway. The Lake Superior shoreline can also be canoed. Camping is allowed only at designated sites.
