Gitnadoiks River Protected Area is located in the heart of the Kitimat Ranges of the Coast Mountains. The Kitimat Ranges are characterized by dome-like granite mountains with many sheer bare faces and numerous waterfalls. Elevations within the park range from about 100 metres in the valley bottom to about 1,800 metres on the surrounding ridges and peaks.
Angling enthusiasts should take note of the excellent sport fishing opportunities available in the park. At least 13 species of fish occur in the area, including Pacific salmon (five species), rainbow and cutthroat trout, Dolly Varden char, and mountain whitefish.
