The Andrews Creek Trailhead outside of Winthrop, WA offers access into the Pasayten Wilderness through the Andrews Creek drainage.  At the trailhead riders will find ample parking for trailers as well as hitch rails. The corrals are in an advanced state of decay and are not safe for use. Highline-able trees are scattered through the area. A vault toilet is located across the road in the hiker’s parking area. Stock water can be sourced nearby in Andrews Creek.

Andrews Creek trail (504) is 16 miles long and runs from the trailhead to the Spanish Camp patrol cabin where it intersects with the Boundary Trail (510). The entirety of the trail has been impacted by the 2003 Fawn Creek Complex fire.
