Second wildfire at Mount Rainier closes Pinnacle Peak Trail — what's still open

Mount Rainier National Park has closed Pinnacle Peak Trail for the second time in a week after the Plummer Peak Fire, which ignited Monday near the popular hiking route, continues to burn through subalpine forest east of Paradise. The fire follows last week's smaller blaze near the same area, raising questions about lightning activity and visitor access during what should be the park's busiest month.

The closure affects one trail in a park with more than 240 miles of maintained routes. Paradise, Sunrise, and the entire Wonderland Trail remain open, along with every major viewpoint and most of the park's infrastructure. If you were planning an August visit, you'll notice smoke in the eastern skyline and maybe a slight haze at higher elevations, but you won't lose access to the experiences that draw more than a million people here each summer.

Mount Rainier National Park

More glaciers than any other Lower 48 peak / Seattle's closest alpine escape

The 14,410-foot volcano looms over Seattle like a piece of the Arctic dropped into the Pacific Northwest. Twenty-five named glaciers wrap the summit, carving valleys that drop through subalpine meadows into temperate rainforest in less than a vertical mile. Paradise gets more annual snowfall than almost anywhere on Earth, yet by late July you can walk through waist-high wildflowers without encountering a single snowbank. The Plummer Peak Fire is burning about two miles east of Paradise in a zone that's visible from Pinnacle Peak Trail but invisible from the main Paradise visitor complex.

Rainier doesn't just dominate the horizon; it creates weather systems that begin at its summit and roll downslope like avalanches made of clouds.

Pinnacle Peak Trail is a four-mile round trip that climbs through meadows to a rocky summit with views across the Tatoosh Range. It's spectacular, but it's not irreplaceable. The Skyline Trail at Paradise covers similar terrain with better wildflower displays and no closure. If you're staying at Paradise Inn or camping at Cougar Rock, you'll barely notice the fire unless you're specifically targeting Pinnacle Peak. The Park Service is monitoring smoke drift, but prevailing winds this week are pushing it east toward Packwood, not west toward the visitor centers.

The fire is burning in a part of the park that already sees fewer visitors than Paradise or Sunrise. Pinnacle Peak shares a trailhead with Plummer Peak, and both routes are considered intermediate climbs rather than family hikes. If you're traveling with kids, your itinerary likely doesn't include either trail. The Trail of the Shadows at Longmire, Reflection Lakes, and the Grove of the Patriarchs are all open and unaffected. Ranger programs at Paradise are running on schedule.

What's worth watching is the cumulative effect of two fires in the same drainage within a week. Lightning is the likely cause for both, and August is prime fire season in the Cascades. The Park Service hasn't indicated any human-caused ignition, and the area is remote enough that accidental starts are unlikely. If you're planning a backpacking trip on the Wonderland Trail or any route east of Paradise, check current conditions daily. Fire perimeters shift fast in subalpine terrain, and closures can expand without much notice.

Sunrise, the park's highest road-accessible point, is 15 miles north of the fire and completely unaffected. The Burroughs Mountain Trail and Emmons Vista remain open, and visibility from Sunrise has been clear most mornings this week. If you were debating between Paradise and Sunrise for your August visit, this tips the scale slightly toward Sunrise, but only slightly. Paradise is still the heart of the park, and the fire isn't changing that.

The closure also doesn't affect the climbing season. Summit routes via Disappointment Cleaver and Emmons Glacier are open, though climbers are being briefed on smoke conditions during permit pickup at the ranger station. Most guided climbs are proceeding as scheduled, and no camps above 10,000 feet are impacted.

For visitors arriving this week, the practical advice is simple: bring your existing itinerary and swap Pinnacle Peak for Skyline, Comet Falls, or any of the dozen other trails in the Paradise area. The park absorbs disruptions like this better than most because its trail network is dense and its景观 doesn't hinge on a single viewpoint. You'll still see the volcano, the glaciers, and the meadows that define Rainier in summer.

The Park Service is updating closure information on its website and at entrance stations. If you're driving in from the Nisqually Entrance, rangers will have current fire maps and can recommend alternatives based on your fitness level and time constraints. The park's sheer size works in your favor here: a two-mile closure in a 368-square-mile park is a footnote, not a crisis.
