Entiako Park is comprised mostly of gently rolling topography, with little physical relief other than the Fawnie Mountains in the northeast.
Forests are predominantly older pine, and the dry, cold growing conditions are inhospitable to most plants. Lichens, however, are abundant in the park, growing where other plants cannot survive. The lichens provide the primary winter forage for woodland caribou, who spend their winters in Entiako Park and summers in Tweedsmuir Park.
An isolated wilderness area, Entiako Park is home to a wide range of wildlife including moose, grizzly bears and wolves. Visitors to the area are few, but those who come enjoy the opportunity to boat, fish, hunt or hike in a truly remote wilderness.
