Reviewed 2026-10-22. Fresh state operator update explicitly says the entire trail and all parking areas are open, while warning improvement work is not finished and additional temporary closures will follow. It specifically names Marysville and Judkins facilities. The Fall River Trestle–Grainville vegetation issue is separate and is not used to promise all trail tread is comfortable or paved. This is a source review, not a same-day inspection. Recheck the linked manager before travel.
Map and Directions
Use the named public start and its posted parking signs. The map reference identifies the facility or selected trail area; it is not a surveyed parking stall or navigable route line. Bicycle and e-bike rules can differ; only ordinary bicycle use is established unless noted.
