Grayback Road

Grayback Road is an out-and-back along a broad gravel remnant of the old Rim Road, mostly through forest with creeks, wildflowers and scenic openings. The park lists it at 8 miles round trip; the mapped Grayback path runs about 4.6 miles one way, so walking its full length out and back comes closer to 9 miles. The public descriptions do not name a turnaround, so treat the distance as approximate and allow about four hours. Choose it for a quieter, longer walk rather than a quick viewpoint stop.

Park at Vidae Falls Picnic Area, then cross East Rim Drive to the closure bar opposite the Crater Peak Trailhead. That is the Grayback Road start. The wide gravel track follows the old road to a junction with Grayback Drive and returns the same way. Its broad surface feels more like a former road than a narrow hiking tread. The park describes forest, creeks, wildflowers and scenic views, but does not say where those features fall along the route or identify a named destination.

This route follows a surviving corridor of the historic Rim Road, the early road that once let visitors circle the caldera. By 1919, roughly 35 miles of rim road were in place; later, modern Rim Drive superseded it. The Grayback section keeps little of the old road beyond its width, so the history is in following that broad line through the forest.

Hikers share this route with bicycles and horses, and leashed dogs are allowed. Grayback is the park’s only trail specifically identified for mountain biking. At this elevation, snow and ice commonly cover high-elevation trails from December into June; during that season the park says trails are unmarked and unavailable for winter or spring hiking. Check current access before setting out.
