Mineral Wash–Bill Williams River Trail Professional Review and Guide
"Most people who visit the Swansea region will travel via the well-used Swansea Road or the Parker-Swansea Road. However, for those with high-clearance 4WDs who want a little more driving excitement, there are two alternative routes into and out of the region. One is from the north, via Rawhide Mountains Trail; the other is through the Bill Williams River National Wildlife Refuge and along Mineral Wash.
Special Attractions: Fording the Bill Williams River many times; Bird-watching in the Bill Williams River National Wildlife Refuge; Varied, remote desert scenery from arid mountains to riparian valleys. High-clearance 4WDs are required. This trail has either a rough, rutted surface, rocks up to 9 inches, mud and deep sand that may be impassable for inexperienced drivers, or stream crossings up to 18 inches deep. Certain sections may be steep enough to cause traction problems, and you may encounter very narrow shelf roads with steep drop-offs and tight clearance between rocks or trees."
