Northern Ontario is well-known for its many pristine rivers and lakes. The Kapuskasing River is no different. It offers a beautiful setting to many sporting activities. The river merges with the Mattagami River, flowing north (as part of the Arctic watershed) towards James Bay and Hudson Bay. The largest body of water, Remi Lake, is situated just east of Kapuskasing. Along with the Opasatika system, it is the most popular recreation area of the region.

Fishing is popular year-round in Kapuskasing. The local fresh water sport fish species are the walleye and pike. Walleye (yellow pickerel) is a favorite among local anglers. Coarse fish such as yellow perch, white sucker and lake whitefish are also common in these lakes and rivers. Although species preferring cold water are not as common, small brook trout can be found in O'Brien Creek.

Kapuskasing boasts a wide variety of wildlife consisting of both large and small animals. The preferred large game includes moose and black bear, while the favoured small game includes ruffed grouse, spruce grouse, sharptail grouse and snowshoe hare. Commercial fur-bearing animals such as beaver, lynx, otter, mink, marten, weasel, muskrat, wolf, fox and red squirrel are also common in the area. 

Several species of waterfowl live in the region of Kapuskasing including golden-eye duck, mallard, mergansers and ring-necked duck. Other migratory birds such as the Canada goose also make regular stops in the area.
