How to get to Mowich Lake with the Fairfax Bridge closed

You cannot drive to Mowich Lake, and as of October 8, 2026, the only legal way to get there is on foot. The State Route 165 Fairfax Bridge, south of Enumclaw by way of Buckley, Wilkeson and Carbonado, carried the one public road to Mowich Lake, Tolmie Peak, Spray Park and the Carbon River corner of Mount Rainier National Park. It has been closed to cars, bicycles and walkers since April 2025, and the Park Service's Carbon River and Mowich page says there is no alternate route. What the park names instead is a walk on the Wonderland Trail, about 27 miles from the Westside Road to Mowich Lake, which for most people means a backpacking trip on a wilderness camping permit and not a day hike. That walk begins in what the park's road report calls an active geohazard zone, where it warns of rock fall and tells hikers and cyclists to pass through with caution and not linger.

Add the park's numbers together and the 6.5-mile round trip to the Tolmie Peak lookout now runs to about 60 miles on foot, car to lookout and back. At the lake itself, the park lists no closure of the trails or the walk-in camp as of October 8, 2026. The park's trail and camp conditions page listed Tolmie Peak as snow free in the summer of 2026, and of the walk-in camp at Mowich Lake a report dated June 25 notes, for whoever turns up, "Bear box in. Toilet open." What is shut is 494 feet of steel and timber over the Carbon River gorge, three miles south of Carbonado, and it belongs to the Washington State Department of Transportation, not to the park.

Is Tolmie Peak closed, and is the Carbon River entrance open?

As of October 8, 2026, the park lists no closure at Tolmie Peak, Spray Park or Mowich Lake. The Park Service says the area remains open to backpackers; what is closed is the road that reached it. By the park's figures it is 6.5 miles round trip from the north side of Mowich Lake to the Tolmie Peak lookout, and 6 miles round trip from the walk-in campground into Spray Park.

The park's hours page still lists the Carbon River entrance as open, with the old road inside it limited to feet and bicycles. But the ranger station there is closed until further notice, the only public road to it crosses the bridge, and the fire closure of fall 2026 begins farther up the valley.

Can you walk or bike across the Fairfax Bridge?

The bridge is closed to people on foot and on bicycles as well as to vehicles. The Department of Transportation, WSDOT, shut it on April 14, 2025, after an inspection, and eight days later made the closure permanent for every kind of traffic. Its release that day said photographs showed a support column "bent in two directions and starting to buckle." The planning study that followed lists bicycle and pedestrian-only designs among the ideas it considered; neither they nor a repair of the old span is among its two recommended options.

Is there a detour to Mowich Lake from Enumclaw?

There is no detour open to the public, from Enumclaw or anywhere else. The Park Service is flat about it: "There is no alternate trail or route open to the public to access Carbon River or Mowich Lake from outside of the park." The routes a mapping app may draw cross private land behind locked gates, it says, and the Foothills Trail does not yet reach the park.

The one road around the gorge is not for visitors. WSDOT describes it as a nine-mile gated logging road, owned by five private landowners, arranged for people who live south of the bridge and for emergency crews. "Under the terms of the agreement we have with the owners, we can't open it to the public," the department wrote on its blog in January 2026.

How far is the walk to Mowich Lake, and where does it start?

The Park Service names two routes, both on the Wonderland Trail, the 93-mile footpath around the mountain: about 27 miles from the Westside Road to Mowich Lake, and about 19 miles from Sunrise to Ipsut Creek Campground on the Carbon River. As of October 8, 2026, the park's pages list a closure on the second and none on the Wonderland Trail sections of the first, though its reports for those sections are dated June and July and it posts detailed trail reports only in summer. One trail that leaves the Westside Road, the Tahoma Creek Trail, is listed as closed by a debris flow and not recommended. The park's fire page, last updated September 21, 2026, lists the Wonderland Trail as closed until further notice from the Carbon River Suspension Bridge to the Sunrise side, and Sunrise Road is closed to private vehicles for the remainder of the 2026 season, according to the park's Alerts page, a notice newer than the Enumclaw to Sunrise guide on this site.

The Westside Road leaves the main park road a mile inside the Nisqually Entrance, about 63 miles and an hour and three quarters from Enumclaw by a routing engine run for this article. Cars may use its first three miles, typically from May to November, to a small lot at Dry Creek. Beyond that the old road is for feet and bicycles, and side trails climb from it to the Wonderland Trail, which runs north past backcountry camps at Klapatche Park, the North Puyallup River, Golden Lakes and the South Mowich River.

It is a summer route. The park says Mowich Lake is generally open from mid-July to mid-October, and that log footbridges wash out in fall and winter and are not replaced until the next year.

Do you need a permit, and is Mowich Lake campground open?

Every night out needs a wilderness permit, and the Mowich Lake campground is open only to walkers who hold one. The park's wilderness permit page says permits must be collected in person. In summer about two thirds can be reserved on Recreation.gov, at $6 plus $12 per person per night, fees the park sets and lists on that page, and the rest are issued at its wilderness information centers no more than a day ahead. The vehicle entrance fee, $30 as of October 2026, is separate, and the park takes cards only.

The Longmire Wilderness Information Center is scheduled to close for the season on October 12, 2026; in winter the park issues permits at the Longmire Museum. The Mowich Lake camp has 13 tent pads, no drinking water and no fires, and a listed season of early July to early October. The park planned to start removing its bear poles, which campers hang food from, on October 4, 2026, and asks late parties to carry a bear canister.

When will the Fairfax Bridge reopen?

WSDOT has closed the old bridge permanently, and nobody has set a date for a new one. WSDOT's planning study, finished in December 2025, kept two options: a new bridge just north of the old one, or a highway left closed. Both remove the 1921 span. The study put a new bridge at about $160 million and six years from first engineering to opening, and permanent closure with removal at $70 million to $80 million and three years. No construction money has been identified.

What exists is about $7 million for drilling, design and environmental review. In its January 2026 update, WSDOT estimated six to twelve months to gather soil and rock data, 24 months for federal environmental review, and 12 to 24 months of property, design and bidding work before a construction contract. The supplemental transportation budget signed on March 31, 2026 tells the department to move quickly and to give lawmakers cost estimates and timelines by January 1, 2027. As of October 8, 2026, WSDOT's news page showed nothing newer.

The 1921 bridge, and what Wilkeson and Carbonado lost

The bridge, which WSDOT's pages also call the Carbon River Bridge, opened on December 17, 1921, the agency says, and its National Register of Historic Places form says Pierce County and the state built it together to give the town of Fairfax its first road. The form describes a 240-foot steel arch and says it was "purported to be the highest span in the state" when new. WSDOT says the bridge was last painted in 1988.

The Courier-Herald reported in December 2025 that the hundreds of cars a day that once came through Wilkeson in peak season had dwindled to almost none. Enumclaw's City Council minutes record Resolution No. 1860 passing 6 to 0 on December 8, 2025, in support of Wilkeson's declaration of the closure as a public infrastructure emergency; the resolution, as the paper quoted it, names hardship in Carbonado too. This site has more on Carbonado, on Wilkeson's coke ovens and on the history of the Carbon River Road beyond the bridge.

Where to hike from Enumclaw instead of Mowich Lake

In fall 2026, with Sunrise Road shut to cars, the nearest thing to Mowich on Enumclaw's side of the mountain is Tipsoo Lake, at Chinook Pass on SR 410: a subalpine lake beside a parking lot, with the 3.4-mile Naches Peak Loop starting from it. The Washington Trails Association puts it about 44 miles from Enumclaw and says the Tipsoo lot needs no parking permit, while the Chinook Pass lot just east needs a Northwest Forest Pass. The highway was open on the park's road report of October 8, 2026, and closes each winter on no fixed date; when Chinook Pass closes has the pattern.

Before you go

Check three park pages on the morning you leave: road status, trail and camp conditions, and the wildland fire page. Call the wilderness information line, 360-569-6650, about permits and river crossings. For the bridge, WSDOT's planning study page has an email sign-up, and the next date to watch is January 1, 2027. And if your phone shows a road around the gorge, the Park Service has answered that one: it crosses private land, and the gates are locked.
