This backcountry park is a massive tract of northern Ontario lowlands, centred on Kesagami Lake and following the Kesagami River for about 80 kilometres, almost to its mouth. One of the most northerly parks in the province, Kesagami is just south of the tree line. Stunted black spruce and the occasional balsam, fir, and larch tree are scattered about the terrain which is frozen for much of the year.

A low rolling kame terrain -- a short ridge of sand and gravel deposited from the water of a melting glacier -- is one of several signs of continental glacial action here. Other natural features are peat cliffs, pillars, and undercuts created by the erosion of the organic soil mat.

The park is home to moose, bear, wolf, otters and martens. Woodland caribou reside around Kesagami Lake.

Park Facilities and Activities:
130 kilometres northeast of Cochrane and 90 kilometres southeast of Moosonee, the park is accessible only by water or float plane via adjacent waters or Kesagami Lake itself or the Harricanaw River which flows into the Kesagami River. The canoe route is unmaintained. There are no park facilities but a commercial lodge occurs in the park. Canoeing, camping, and fishing are permitted here. Hunting is not.

The park was originally regulated in 1983, with a subsequent update of the boundary in 1984.

This wilderness class park is designated by regulation under the Provincial Parks and Conservation Reserves Act, 2006.
