Search “is North Cascades National Park open” this week and you’ll mostly find scattered local news — a Whatcom County fire story here, a Skagit Valley update there, nothing that adds up to the full picture. The full picture is on the park’s own fire closures page, and it’s more serious than the coverage suggests: two wildfires that have been burning inside North Cascades National Park since early July have closed the entire Hozomeen area and the US–Canada border crossing that sits inside the park boundary. Not a trail. Not a campground. A border crossing.

Short version: yes, most of the park is open. Highway 20, Newhalem, Diablo Lake — all reachable. But the northern end, where Ross Lake meets Canada, is shut down in a way that’s unusual even by this summer’s standards.

Quick Verdict: North Cascades National Park, Aug. 31, 2026

Area	Status
Highway 20 / Newhalem / Diablo Lake	Open (not on the closure list — confirm conditions before you drive up)
Hozomeen area (docks, camping, public access)	Closed
US–Canada border crossing at Hozomeen	Closed to foot and vessel traffic
Ross Lake, Lightning Creek to the border	Closed to boats
Big Beaver Trail (Ross Lake to Little Beaver junction)	Closed
Little Beaver Trail (Ross Lake to Whatcom Pass)	Closed
Sourdough Mountain Trail	Closed
Border 2 Fire	7,633 acres (US side), 73% contained
Luna Fire	5,470 acres, 27% contained

In one sentence: The Border 2 and Luna fires have closed the entire Hozomeen area, the in-park US–Canada border crossing, and a long stretch of backcountry along Ross Lake, while Highway 20 and the park’s main developed areas remain open.

What’s Actually Burning

Two fires, both lightning-caused, both still active more than a month after they started.

The Luna Fire started July 2 in a rock scree southwest of Luna Camp on the Big Beaver Trail — steep, remote terrain that made early access genuinely hard. It grew slowly at first (392 acres by July 31), then picked up: 950 acres by August 2, burning on both sides of Big Beaver Creek. By August 19 it had reached 4,477 acres with zero containment, roughly 10 miles north of Newhalem, with 87 firefighters assigned and only “minimal growth” reported day to day. As of Aug. 31, the fire sits at 5,470 acres and 27% contained.

The Border 2 Fire started two weeks later, on July 16, east of Ross Lake near Little Jackass Mountain, right along the international boundary. It grew fast: 3,500 acres by July 31, past 5,028 acres by Aug. 2, and up to a combined 14,336 acres (US and Canadian sides together, with about 6,556 on the US side) by Aug. 14. By Aug. 20 the US portion had reached 7,296 acres at 43% contained. As of Aug. 31, it’s at 7,633 acres and 73% contained — real progress, but crews are still working it, not walking away from it.

The two fires are burning roughly 12 miles apart, Luna to the southwest, Border 2 up against the Canadian line. They’re not the only fire activity in the complex this month, either — Thunder Creek and Sisi fires have closed sections of trail near Stehekin, on the park’s southern end, though neither comes close to Border 2 or Luna in scale or in what it’s closed.

Is North Cascades National Park Open Right Now?

1. Yes, for the parts most visitors actually drive to. Highway 20 through Newhalem and Diablo Lake isn’t listed among the current closures. That’s where the scenic overlooks, the visitor center, and most day-trip itineraries live.
2. No, not Hozomeen. The entire Hozomeen area — docks, campground, public access — is closed, and has been since the Border 2 Fire put it directly in the fire’s path.
3. No, not the US–Canada border crossing at Hozomeen. Foot and vessel traffic across the border is prohibited while the fire burns on both sides of the line.
4. No, not Ross Lake north of Lightning Creek. Boats can’t get up to the border, which cuts off the water route to Hozomeen even for people not trying to cross into Canada.
5. No, not Big Beaver or Little Beaver Trails, from Ross Lake all the way to Whatcom Pass, plus Sourdough Mountain Trail and a long list of backcountry camps — Pumpkin Mountain, Luna, Beaver Pass, 39 Mile, Twin Rocks, Stillwell, Pierce Mountain, and boat-in sites at Boundary Bay, Silver Creek, Little Beaver, Cat Island, and Lightning Creek among them.

Why Hozomeen Is a Bigger Deal Than a Trail Closure

Most park wildfire closures this season have followed the same pattern: a trail here, a campground there, a road corridor if things get bad. Hozomeen is different. It’s not one attraction inside the park — it’s an entire region of it, the northern anchor of Ross Lake, and the only place inside North Cascades where you can walk or boat across an international border.

Closing that isn’t a matter of steering visitors toward a different trailhead. It removes an entire travel option — the cross-border backcountry route between Ross Lake and Manning Park in British Columbia — for as long as fire crews need the corridor clear. And with Border 2 still at 73% rather than fully contained after more than six weeks, and Luna sitting at just 27% after nearly two months, “as long as it takes” doesn’t have a date attached yet.

Washington’s statewide burn ban, which Gov. Bob Ferguson put in place Aug. 1 after the state topped 425,000 acres burned for the year, is the backdrop for all of this. It’s not specific to North Cascades — it covers campfires, debris burning, and agricultural burning statewide through Sept. 30 — but it’s the same signal Everglades and Mount Rainier posts have carried all season: wildfires have been closing bucket list trails across the West and beyond this year, and conditions aren’t easing up just because summer’s winding down.

What This Means If You’re Planning a Visit

A few things worth doing before you lock in a date:

• Plan around Highway 20, not Ross Lake’s north end. Newhalem, Diablo Lake, the scenic pullouts along the highway corridor — none of that is affected. If your trip was built around those, proceed as planned and just check conditions again close to your date.
• Cross off Hozomeen entirely for now. No docks, no camping, no border crossing on foot or by boat. If a cross-border Ross Lake–to–Manning Park itinerary was the whole point of your trip, that’s not happening this season.
• Rebuild Ross Lake backcountry plans around what’s open. Big Beaver, Little Beaver, and Sourdough Mountain are out, along with most of the boat-in camps on the lake’s northern half. The southern end of Ross Lake, reachable from Highway 20, is a better bet.
• Watch containment, not just acreage. Border 2 at 73% contained is meaningfully further along than Luna at 27%. If your trip touches the Big Beaver Trail corridor specifically, that’s the slower-moving one to track.
• Bring the statewide burn ban into your planning, separate from the trail closures — no campfires anywhere in Washington through Sept. 30, this park included.

Planning Around It

If you’re still deciding whether to book, here’s the actual tradeoff.

Go ahead and plan if: your trip centers on the Highway 20 corridor — Newhalem, Diablo Lake, the roadside viewpoints most visitors come for. None of that is touched by either fire.

Reconsider or reroute if: Hozomeen, the cross-border Ross Lake route, or Big Beaver/Little Beaver backcountry camping were the point of the trip. Those aren’t back this season, and Luna’s containment number says that corridor is still weeks out at best.

Either way: this is the same story that’s played out at Mount Rainier and the Everglades this month — a national park that’s genuinely open, with a specific, significant piece of it that isn’t. Read the actual status, not the headline, and check the park’s own page within a few days of departure rather than trusting a week-old article, including this one. If you’re weighing which Pacific Northwest park to prioritize this season, Glacier’s 2026 shuttle and access rules are worth a look too — different park, same theme of “open” meaning something more specific than it used to.

The Bottom Line

North Cascades National Park is open — Highway 20, Newhalem, and Diablo Lake are all reachable right now. What’s closed is unusually significant for a wildfire closure: the entire Hozomeen area, the US–Canada border crossing inside the park, Ross Lake north of Lightning Creek, and the Big Beaver and Little Beaver Trail corridor out to Whatcom Pass. Border 2 is 73% contained as of Aug. 31; Luna is at 27%. Neither is out. Check the fire closures page again close to your travel date, plan around the Highway 20 corridor rather than the park’s northern tip, and don’t assume this article — or any single one — is more current than what NPS is posting itself.
