Trailheads
The Forest Service recreation layer records no trailhead within a third of a mile of this trail's line. Many trails start from a road pullout or another trail with no trailhead record. The forest's recreation pages list the trailheads it does publish.
Distance is from the point to the nearest part of the trail line. Season text is what the forest wrote and is often a season name rather than a date. The recreation page link goes to the Forest Service site, which may redirect to the forest's recreation index.
