Pukaskwa National Park is a national park located south of the town of Marathon, Ontario in the Thunder Bay District of northern Ontario, Canada. Established in 1983, Pukaskwa is known for its vistas of Lake Superior and boreal forests. The park covers an area of 1,878 km² and is the largest national park in Ontario. This park was named after the Pukaskwa River. The highest point in the park is the peak of Tip Top Mountain which is the third highest point in Ontario. Thousand year old rock structures known as Pukaskwa Pits which were created by the original inhabitants of this area can be found on many of the park's cobblestone beaches.  A small population of Woodland Caribou can be found in the park. 

There is a campground at Hattie Cove located at the north end of the park which can be accessed via Highway 627, the only road access into the park. There are also a number of backcountry campsites located along a hiking trail which follows the north shore of Lake Superior.
