Mount Rainier National Park and the Grove of the Patriarchs closure are affecting autumn visits near Ashford from 5 October 2026. The National Park Service has closed the parking lot while crews prepare a replacement bridge, with work continuing through 31 October.
Grove of the Patriarchs closure runs through 31 October
The closure covers the Grove of the Patriarchs parking lot seven days a week from 5 October to 31 October 2026. The park says geotechnical drilling and other preparation work will support a new bridge and trail route to the grove.
Helicopters will transport equipment during the work. Operations are scheduled from 7am to 5pm every day, including weekends, and temporary closures near the work zone can last up to 30 minutes. The National Park Service construction schedule also says Stevens Canyon Road will close to all visitor traffic at 7am on 26 October 2026.
Flood damage shapes the current access plan
The Grove of the Patriarchs is an island site in the Ohanapecosh River. A severe flood in November 2021 caused major structural failure of its 1961 suspension bridge, which was removed for safety.
The grove itself is closed to recreation, so the October work adds a parking restriction to an existing trail closure. The replacement project is scheduled for the 2027 and 2028 seasons, while preparation work in October 2026 brings the first major visitor effects linked to that project. The timing connects a short-term access change with a longer rebuild of the route to the island.
Mount Rainier National Park lies in Washington State, with its headquarters address in Ashford. The park rises to 14,410 feet (4,392 m) at Mount Rainier and includes the Wonderland Trail, subalpine meadows, glaciers and old-growth forest. The mountain is an active volcano and the most glaciated peak in the contiguous United States, according to the park overview.
October road restrictions extend beyond the grove
Visitors approaching the area should distinguish between the parking-lot closure and the wider road changes. Stevens Canyon Road may close temporarily during helicopter operations, while SR 123 near the junction can operate with a single lane during construction hours.
On 26 October 2026, Stevens Canyon Road will close to visitor traffic at 7am. The park directs visitors to use the Nisqually Entrance on the west side as an alternative route for entry and exit on that day.
