The Anderson Pass / Sanctuary Pass loop is a six day trek along an unblazed remote backcountry route through pristine valleys and tundra of the Alaska Range.
To reach the hiking trailhead, use the National Park bus from the main visitor center to the Sanctuary River stop.
The route begins by heading south through a wide valley and up to the headwaters at a high pass. After a steep ascent of West Fork of Windy Creek, the route proceeds to Foggy Pass and then on to Easy Pass. Then after following the West Fork Of The Chulitna River, ascend over Anderson Pass which has vistas of Mt McKinley. The route ends at the Eielson Visitor Center where a bus returns to the main visitor center.
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, Anderson Pass / Sanctuary Pass is the 33rd most popular hiking trail of all 54 hikes in Alaska.
