The Jack-Ash trail is named for a proposed connection between the cities of Jacksonville and Ashland Oregon. The current Phase 1 of the envisioned long distance non-motorized trail connects portions of the historic Sterling Mine Ditch Trail to existing roads and historic trails, and 4.7 miles of new trail construction up and over Anderson Butte. The trail offers a multitude of vistas and vegetation types for equestrian, mountain bikes, and hikers. The trail does utilize existing and historic sections of road along it's path. Equestrian and bike users are reminded to avoid use after significant precipitation to prevent damage to the trail.
