The Booking Reality
Colonial Creek is the only developed frontcountry campground inside North Cascades National Park proper. Summer weekend sites book out months in advance. Reservations for July and August open on Recreation.gov at 7 AM Pacific on a rolling 6-month window. Friday-through-Sunday sites are typically gone within 15 to 30 minutes of release. If you're not logged into Recreation.gov with payment info saved before the booking window opens, you'll be refreshing a sold-out calendar.
Monday through Thursday sites are easier to secure, often remaining available 1 to 2 weeks out. The exceptions are holiday weeks - Fourth of July and Labor Day - where Tuesday and Wednesday fill alongside the weekend slots.
Goodell Creek Campground, located just outside the park boundary in the Ross Lake National Recreation Area, operates on a first-come, first-served basis and rarely fills completely except on peak-season holiday weekends. Newhalem Creek Campground, also in the NRA, takes reservations and tends to have more availability than Colonial Creek.
The park has no RV hookups at any campground. No showers either. Plan accordingly.

Colonial Creek Campground: Complete Guide
Setting and Atmosphere
Colonial Creek sits on both sides of State Route 20 at the south end of Diablo Lake. The campground is split into North and South loops, each with distinctly different character. You'll hear the creek from most sites - a constant low rumble that masks road noise from the highway. The forest canopy is dense Douglas fir and western hemlock, which means shade nearly everywhere and damp ground even on dry days.
The North Loop is quieter. Sites are more spread out, and the understory vegetation between sites provides better visual privacy. The South Loop is closer to the lake and the boat launch, which means more foot traffic and occasional boat noise during daylight hours.
Colonial Creek is the most popular campground in the park complex for good reason: it's the only one that puts you directly on Diablo Lake with trailhead access to the Thunder Creek and Diablo Lake trails.
Loop by Loop Breakdown
North Loop (Sites 1-49): These are the sites to target if you want privacy. The loop is one-way, narrow, and tight for larger RVs - anything over 25 feet will struggle with the turns. Sites 8 through 17 back up against the creek and offer the best sound insulation from the highway. Sites 25 through 33 are in a dense stand of old-growth hemlock with thick understory between neighbors. Sites 1 through 4 are closest to the highway and get noticeable road noise - skip these if you're a light sleeper. South Loop (Sites 50-94): These sites are more open and easier to access with larger RVs and trailers. Sites 60 through 72 have partial views of Diablo Lake through the trees - not full lake views, but enough blue-green water visible to make morning coffee feel intentional. Sites 50 through 55 are closest to the vault toilets and the generator hum from the maintenance area. Sites 80 through 94 are walk-in tent sites that require carrying gear 50 to 150 feet from the parking pullout. These walk-in sites are the best option for tent campers who want to avoid RV generator noise.Specific Site Recommendations
Best for families: Site 47 (North Loop) - flat, roomy, close to restrooms, and has a large tent pad. Site 72 (South Loop) - near the boat launch and a short walk to the lake. Best for solitude: Site 14 (North Loop) - farthest from neighbors on both sides, backed against the creek. Site 17 (North Loop) - similar setup with more understory screening. Best for RVs under 25 feet: Sites 35, 36, and 37 (North Loop) - pull-through, relatively level, minimal overhanging branches. Sites to avoid: Site 1 (highway noise, no privacy). Site 50 (right next to the vault toilet - the door latch is loud at night). Site 55 (generator noise from the maintenance area).Facilities Detail
Colonial Creek has flush toilets in both loops, but no showers. Potable water spigots are located near the restroom buildings. There is no dump station - the nearest one is at the Marblemount ranger station, 22 miles west. Garbage collection is at the entrance to each loop; pack out what you pack in is the stated policy, but bear-proof dumpsters are available.
What the Booking Site Doesn't Show
The road noise from SR 20 is more noticeable than you'd expect from the map. The highway runs between the North and South loops, and while traffic drops significantly after dark, the logging trucks start rolling again around 5 AM. This is especially true on weekdays.
Bear activity is regular. The park service reports multiple bear incidents at Colonial Creek each summer, usually involving improperly stored food. The food storage lockers at each site are mandatory - rangers check compliance during evening rounds.
The Diablo Lake boat launch at Colonial Creek South is currently inaccessible to powerboats due to silt accumulation. As of 2026, expect shallow or no water at the launch ramp. You may need to carry your boat to or from the water.
Cell service drops out at Colonial Creek. There's no signal on either loop. The nearest reliable signal is at the Diablo Lake Overlook, about 2 miles east, or at the Newhalem visitor center area.
Goodell Creek Campground: Complete Guide
Setting and Atmosphere
Goodell Creek is the raw option. Located just off SR 20 about 2 miles west of Newhalem, this 21-site campground has no potable water, no flush toilets, and no reservations. It's first-come, first-served by design, and it attracts a specific type of camper - the kind who doesn't mind vault toilets and filters creek water.
The sites are spread along a gravel access road that runs parallel to Goodell Creek. The forest here is second-growth mixed conifer, less dense than Colonial Creek, which means more sunlight and drier ground. The creek is audible from every site and provides a consistent white noise that covers the highway.
Site-Specific Notes
Sites 1 through 7 are closest to the creek and have the best sound environment. Sites 8 through 14 are more open and get better afternoon sun - good for drying gear but less privacy. Sites 15 through 21 are at the far end of the loop and are the most private, but they're also the farthest from the vault toilets.
There's no generator hour enforcement culture here the way there is at Colonial Creek. Expect generators running at odd hours. If quiet matters to you, bring earplugs.
Facilities Detail
Vault toilets only. No potable water - you'll need to bring your own or treat creek water. No garbage service - pack everything out. The nearest dumpster is at the Newhalem visitor center, 2 miles east.
Goodell Creek stays open year-round, but the road beyond it closes in winter. From November through April, you can access Goodell Creek but cannot continue east on SR 20 past the Ross Dam Trailhead. The campground gets very little use in winter - you'll likely have it to yourself, but snow is common at this elevation.
Newhalem Creek Campground: Complete Guide
Setting and Atmosphere
Newhalem Creek sits in the company town of Newhalem, which is Seattle City Light's operational base for the Skagit River Hydroelectric Project. The campground is 47 sites arranged along a loop road with the creek on one side and the town's infrastructure on the other.
This is the least "wild" feeling campground in the area. You can hear the power plant from some sites. The forest is managed - cleared understory, maintained paths, and a general sense of order that feels more like a state park than a national park campground.
But it has amenities Colonial Creek doesn't. Potable water. Flush toilets. A general store within walking distance. The North Cascades Visitor Center is a 5-minute walk away. If you're traveling with someone who needs creature comforts, this is your pick.
Site Selection
Sites 1 through 12 are along the creek and are the best in the campground - good sound, some privacy, and the coolest temperatures on hot days. Sites 20 through 30 are in the open and get full sun; these are the only sites in the area where you can reliably dry out gear. Sites 35 through 47 are closest to the road and the power plant - the hum is constant.
Facilities Detail
Flush toilets, potable water, and a dump station located at the campground entrance. There's a pay shower at the Skagit General Store in Newhalem - $5 for 5 minutes as of 2026. The store sells camping fuel, ice, basic groceries, and surprisingly good coffee.
Hozomeen Campground: Complete Guide
Setting and Atmosphere
Hozomeen is the wild card. Located at the north end of Ross Lake, accessible only by boat or by driving through Canada, this 57-site campground is free and first-come, first-served. The gate at the US-Canada border remains closed as of 2026 - vehicle and foot traffic across the border is prohibited. Visitors must enter through a designated port of entry.
This means Hozomeen is currently only accessible by boat from Ross Lake or by hiking the East Bank Trail. It's a destination for paddlers and backpackers, not car campers.
If you can get there, the setting is unmatched - sites are spread along the lakeshore with views of Hozomeen Mountain and the Picket Range. Vault toilets and hand-pump water are available. No fees. No reservations. No crowds.
Reservation Strategy
Recreation.gov Tactics
For Colonial Creek and Newhalem Creek, the booking window opens at 7 AM Pacific, 6 months out from your arrival date. The system releases sites in batches, not all at once. If you see "sold out" at 7:01, refresh at 7:05 and again at 7:15 - cancellations from the initial booking rush often appear in the first 20 minutes.
Create your Recreation.gov account ahead of time. Save your payment information. Have your preferred site numbers written down before the window opens. The site map on Recreation.gov is usable but slow - know which loop you want before you're clicking through the interface.
Cancellation Monitoring
Cancellations happen regularly, especially 2 to 3 weeks out when people finalize their summer plans. Set up alerts on Recreation.gov for your desired dates. Check the site at 7 AM Pacific daily - cancellations are released at the same time new bookings open.
For Colonial Creek, cancellations for Thursday and Sunday nights are more common than Friday and Saturday. If you can flex your schedule, look for Thursday arrival / Sunday departure patterns.
Walk-In Availability
Colonial Creek holds approximately 10 sites for walk-in first-come, first-served use. These sites are released at 2 PM daily. The line forms at the campground host site around 1 PM during peak season. If you arrive before noon on a weekday, you have a reasonable chance at a walk-in site. On Friday afternoons in July and August, expect the walk-in sites to be claimed within 30 minutes of release.
Goodell Creek almost always has availability on weekdays. On summer weekends, arrive before 11 AM to secure a site.
What to Know Before You Arrive
Bear Storage: Food storage lockers are provided at every site at Colonial Creek and Newhalem Creek. Use them. The park service fines for improper food storage - $125 per violation as of 2026. Do not leave food in your vehicle overnight. Bears in this area have learned to associate cars with food, and a broken window is the least of your problems if a bear gets inside. Fire Restrictions: Campfires are allowed in designated fire rings at all campgrounds, but fire restrictions vary by season. Check the park's fire restrictions page before you arrive. In August, when fire danger is highest, charcoal grills are often prohibited. Propane stoves and camp stoves are almost always allowed. Quiet Hours: Enforced from 10 PM to 6 AM at Colonial Creek and Newhalem Creek. Generator use is prohibited during quiet hours. At Goodell Creek, enforcement is less consistent - the campground host is seasonal and not always present. Cell Service: None at Colonial Creek. None at Goodell Creek. Spotty at Newhalem Creek - you might get a bar near the visitor center. The best signal in the area is at the Diablo Lake Overlook, about 2 miles east of Colonial Creek. Water: Colonial Creek and Newhalem Creek have potable water during the operational season. Goodell Creek does not - bring your own or treat creek water. Giardia is present in all surface water in the North Cascades. Filter or boil everything. Checkout Time: 11 AM at all campgrounds. The campground host will do a sweep starting at 11. Don't push it - they've seen every excuse. Vehicle Break-Ins: Break-ins are common at trailheads along SR 20. Remove valuables and electronics from your vehicle. Take the charging cables with you - thieves look for cables as a sign of electronics inside.
