The Muddy Creek route to Peters Dome is a six-day out-and-back trek with numerous water crossings and an unblazed remote backcountry route.
To reach the hiking trailhead, use the National Park bus from the main visitor center to the Wonder Lake bus stop.
The route begins by following the McKinley River to a passible section near the muddy River. The trek passes through spruce and adler taiga forest. Expect plenty of rocky creek crossings, which should only be attempted during dry season. Follow Muddy Creek south to Peters Glacier, which is on the north side of Mt McKinley. Keep an eye out for moose, grizzley and the national bird -- the mosquito.
Note, a backcountry permit is required. A map, navigation skills and compass skills are essential.
Overall, Peters Dome is the 34th most popular hiking trail of all 54 hikes in Alaska.
