Campgrounds near Custer, Washington
Custer sits in northwest Whatcom County, a few miles inland from Birch Bay and roughly 20 minutes north of Bellingham via Interstate 5. The Canadian border at Blaine is about 10 minutes north, which makes the area a common first or last stop for RV travelers crossing into or out of British Columbia.
The surrounding camping market is dominated by private RV resorts and one major state park. Birch Bay State Park anchors the area with saltwater shoreline on Birch Bay and freshwater frontage along Terrell Creek, all within a short drive of Custer. Private options closest to Custer include The Cedars RV Resort, Lighthouse By The Bay RV Resort, Beachside RV Park, Ball Bayview RV Park, and Birch Bay RV Campground, most offering full hookups suited to larger rigs.
The combination of saltwater beach, flat cycling roads, cross-border access, and a high concentration of full-service RV parks makes Custer a practical base for families who want hookups and a tide-flat shoreline within a short drive.
Things to do near Custer
The shoreline at Birch Bay is the main draw. Visitors head to the beach at low tide to harvest clams, mussels, and oysters, swim in the relatively warm shallow water on hot days, watch birds at Terrell Marsh, and set crab pots from the shore. Crabbing season at Birch Bay normally begins in mid-August, and a Washington recreational license is required for fishing and shellfish harvesting at state parks.
On land, the Birch Bay Drive promenade is flat and bike-friendly, and the half-mile Terrell Marsh Interpretive Trail with interpretive signs works well for short family walks. Day trips include Bellingham, the Birch Bay waterslide park, Peace Arch at the Blaine border crossing, and Mount Baker viewpoints inland.

Summer is the peak season at Birch Bay State Park. The campground is busiest on summer weekends and holidays, though summer weekdays can also fill up, while spring and fall are quieter, with sites generally available without much advance planning. Mid-August through September is the traditional window for crabbing and shellfish harvest, which drives extra demand at waterfront sites.
Winter camping is possible but stripped down at the state park. From September 16 through May 14, camping shifts to a first-come, first-served basis in the North Loop (sites 1-38). Water may be shut off during these months for winterization. The park is typically winterized by late November and de-winterized by late March, with a limited winter water supply available in the North Loop.
Private RV resorts in the Custer and Birch Bay area generally stay open year-round, though some amenities such as pools, laundry rooms, and planned activities run only during the warm-weather months.
How to book
Birch Bay State Park uses the Washington State Parks reservation system. Campsites are reservable for arrival dates from May 15 through September 15, and the park is open year-round for camping, though some sites are closed in winter. Reservations can be made up to nine months in advance and can be booked online or by calling (888) 226-7688. Summer weekends often book out as soon as the nine-month window opens, so set a reminder rather than waiting until the trip month.
A Discover Pass is required to park a vehicle for day use at Washington state parks, available as a one-day pass or annual pass. Camping fees include the day-use pass for registered campers. Private resorts including The Cedars RV Resort, Lighthouse By The Bay RV Resort, Beachside RV Park, Ball Bayview RV Park, and Birch Bay RV Campground book directly through their own websites or by phone.
What to expect on site
Birch Bay State Park offers 147 standard forested sites, 20 water and electric partial-hookup sites, two primitive sites, a trailer dump station, eight restrooms, and 18 showers, and accommodates RVs and combinations up to 60 feet in length. Sites sit in second-growth forest a short walk from the beach, so expect shade, cedar duff, and uneven afternoon sun for solar panels.
Full hookups are the exception at the state park and the rule at the private resorts in the area. Cellular service is generally usable along the I-5 corridor and weakens in the more wooded loops. Pets are allowed on leash at most properties, and at Birch Bay State Park pets are not permitted on designated swimming beaches.
Noise from the BP Cherry Point refinery and rail traffic can be audible at the state park, particularly in the eastern loop, so light sleepers may prefer sites farther west or a private resort closer to the beachfront.

Frequently asked questions about campgrounds near Custer, WA
How much does it cost to rent an RV in Custer, WA?
RV rentals in Custer typically range from about $90 to $200 per night for travel trailers, $150 to $275 for Class C motorhomes, and $250 to $400+ for larger Class A coaches. Because Custer sits right on the I-5 corridor between Bellingham and the Canadian border, you'll often find better value here than in busier Seattle metro listings. To score a cheap RV rental in Custer, book mid-week shoulder-season trips (April, May, late September), filter by Instant Book to see hosts with quick acceptance, and look for listings with unlimited or generous mileage included. Pro tip: many local hosts discount weekly stays by 10 to 20 percent, which makes a week at Birch Bay State Park surprisingly affordable.
parks.wa.gov/find-parks/state-parks/birch-bay-state-parkDo I need a special license to rent an RV in Custer, WA?
Good news: a regular driver's license is all you need to rent an RV in Custer, no Commercial Driver's License (CDL) or special RV endorsement is required in Washington State, even for larger Class A motorhomes. RVezy's approved driver guidance generally requires renters to be 25 or older, and your ID is verified through the platform when you book, so there's nothing extra to mail in. Visiting from outside the United States? Bring your home-country license plus an International Driving Permit (IDP) from your local auto association and you're set. Most first-time renters in Whatcom County are surprised how quickly the process moves.
help.rvezy.com/hc/en-us/articles/360039008774-Understanding-approved-driver-requirementsWhat protection is included with my Custer RV rental?
Every RV rental in Custer booked through RVezy includes a renter protection plan plus 24/7 roadside assistance, so you can roll out toward Mount Baker or the San Juans with confidence. At checkout you choose your protection level, with different plans offering different deductibles and coverage limits, so you decide how much peace of mind feels right (the host does not set this). The plan covers accidental physical damage to the RV, which is reassuring for first-timers learning to back into a site at Birch Bay State Park. Review the full details on RVezy's protection page before you finalize, so you know exactly what is and isn't covered on your Custer RV trip.
help.rvezy.com/hc/en-us/articles/34008759079835-RVezy-renter-protection-plans-in-detailWhat if I need to cancel my Custer RV rental?
You're not locked in the moment you book. RVezy has its own cancellation policy (set by RVezy, not the host) that includes a short money-back grace period right after booking. The exact refund depends on how far ahead of your trip you cancel, so review the policy on RVezy's Help Center before you finalize. If a host ever cancels on you, RVezy refunds your booking or offers travel credit so you're not left without a rig. The takeaway: booking your Custer RV trip is low-risk, and RVezy support is reachable if plans change before departure.
help.rvezy.com/hc/en-us/articles/360037736674-Understanding-the-cancellation-policy-for-guestsCan I bring my dog on a pet-friendly RV rental in Custer?
Absolutely, plenty of hosts offer pet-friendly RV rental in Custer. Just use the Pet-Friendly filter when searching listings, and you'll see options that welcome dogs (some welcome cats too). Whatcom County is a dream for dog owners: Birch Bay State Park allows leashed pets on trails and most areas (just not the designated swim beach), and the 3.5-mile Birch Bay Beach walkway is a favorite for sunset strolls with your pup. Pro tip: message your host before booking to confirm size, breed, or cleaning-fee details, then pack a towel for sandy paws coming off Drayton Harbor.
parks.wa.gov/about-us/rules-and-safety/park-rules-and-regulationsCan the RV be delivered to my campsite in Custer?
Yes, RV delivery in Custer is one of the most popular options on RVezy, especially for first-timers. Many local hosts will tow or drive the rig straight to Birch Bay State Park, The Cedars RV Resort, or even a private driveway near Blaine or Ferndale, then level it, hook up power and water, and walk you through every system before handing over the keys. Use the Delivery filter to see hosts who offer this service and check their delivery radius and fees on each listing. It's the easiest way to enjoy a Custer RV trip without ever driving the RV yourself, perfect for families flying into Bellingham International Airport (BLI), only 15 minutes south.
portofbellingham.com/156/Bellingham-International-AirportHow far can I drive on an RV rental from Custer?
Custer is one of the best launch pads in the Pacific Northwest for an RV road trip. From here, Mount Baker Ski Area is about 65 miles east, Deception Pass State Park is roughly 60 miles south, North Cascades National Park sits about 100 miles east via Highway 20, Olympic National Park is around 200 miles southwest, and Seattle is just 100 miles down Interstate 5. Most hosts include a daily mileage allowance (often 100 to 150 miles per day) with extra miles at a per-mile rate, and some offer RV rental with unlimited mileage. Pro tip: ask the host directly through the listing if you're planning a long loop, many will negotiate a flat mileage package.
nps.gov/noca/index.htmWhere are the best campgrounds near Custer, WA?
You're spoiled for choice for RV camping in Custer. Birch Bay State Park (5 miles west) offers 147 standard sites and 20 water-and-electric sites right on the saltwater bay, reservable mid-May through mid-September. The Cedars RV Resort in Ferndale has full hookups and big-rig friendly pull-throughs. Lynden/Bellingham KOA Holiday (about 12 miles east) is a family favorite with a pool and mini-golf. Sunny Point RV Resort in Ferndale serves up Mount Baker views, and Larrabee State Park (about 25 miles south near Bellingham) is open year-round with electric and sewer hookups. Pro tip: Birch Bay sites book out fast for July and August, so reserve nine months ahead through washington.goingtocamp.com.
parks.wa.gov/find-parks/state-parks/birch-bay-state-parkWhen is the best time to visit Custer, WA in an RV?
The sweet spot for RV camping in Custer is mid-June through mid-September, when daytime highs settle into the mid-60s to low 70s and the rain finally takes a break. July and August are the warmest and driest months, with average highs around 70°F and long Pacific Northwest sunsets stretching past 9 p.m. May, early June, and September are excellent shoulder-season picks: cooler (mid-50s to mid-60s) and quieter, with lower nightly rates. Winter RV trips are possible, but expect frequent rain, highs in the low 40s, and water shutoffs at Birch Bay State Park's reservable loop. For a classic family RV trip in Custer, target the last two weeks of July.
weather.gov/sew/I've never rented an RV before. Will I be okay driving in Custer?
First time renting an RV? You're in great hands. Custer sits in flat, rural Whatcom County right off Interstate 5, with wide shoulders, straightforward exits, and far less traffic than Seattle or Vancouver. Your host gives you a full walkthrough at pickup, covering the propane, water systems, slides, and backing-up tips, and they're a text away during your trip. RVezy's 24/7 roadside assistance is included if anything feels off. Pro tip: practice a few right turns in the Birch Bay Square shopping plaza parking lot before heading to your campsite, and you'll feel confident long before you reach the Mount Baker foothills.
wsdot.wa.gov/travel/real-time/traffic-camerasWhat happens if something goes wrong on the road?
You're never stranded. Every RV rental in Custer booked through RVezy comes with 24/7 roadside assistance as part of the renter protection plan, covering common headaches like flat tires, dead batteries, lockouts, and tow services. If a system inside the RV acts up (think furnace, fridge, or slide-out), your host is your first call, they know their rig best and can usually walk you through a fix in minutes. RVezy's customer support team is also available before, during, and after your trip if you need extra help. Custer's location near Bellingham means service shops and parts are close by, not hours away in the backcountry.
help.rvezy.com/hc/en-us/articles/34008759079835-RVezy-renter-protection-plans-in-detailCan I drive the RV across the border into Canada?
Custer is only about 7 miles from the Peace Arch border crossing into British Columbia, so cross-border trips are a natural question. Many RVezy hosts allow Canada travel (Vancouver, Whistler, and the Sea-to-Sky Highway are stunning RV destinations), but it depends on the individual host's insurance, so message them through the listing before booking to confirm. Travel into Mexico is not permitted on any RVezy rental. Pro tip: if Canada is approved, bring your passport, declare any food or firewood at the border, and consider the Pacific Highway crossing just east of Blaine to skip long summer waits at the main Peace Arch lanes.
cbp.gov/travel/us-citizens/know-before-you-goHow much should I budget for fuel on a Custer RV trip?
Fuel is usually the biggest variable cost on a motorhome rental in Custer. Most Class C motorhomes get 8 to 12 miles per gallon (MPG), Class A coaches around 6 to 10 MPG, and a campervan rental in Custer can stretch to 15 to 20 MPG. Washington gas prices typically run above the national average; as of recent months, regular unleaded in Whatcom County hovers around $4.10 to $4.60 per gallon, with diesel slightly higher. For a 4-day loop covering 400 miles in a Class C, plan for roughly $150 to $200 in fuel. Pro tip: fill up at the Costco in Bellingham or the Arco off Birch Bay Lynden Road for the cheapest pumps in the area.
eia.gov/petroleum/gasdiesel/How far in advance should I book a campground near Custer?
For summer weekends at the best campgrounds near Custer, book as early as you can, ideally the day they open up. Washington State Parks releases reservations exactly nine months in advance at 7 a.m. Pacific, and Birch Bay State Park's waterfront sites disappear within minutes for July and August dates. Reservations run through washington.goingtocamp.com (the official state system) with an $8 online fee. Private parks like The Cedars RV Resort and Lynden/Bellingham KOA accept reservations on their own websites and tend to have more flexibility 1 to 2 months out. Pro tip: weekday stays are far easier to grab last-minute, so a Sunday-to-Thursday trip is a smart play.
parks.wa.gov/passes-permits/reservations/making-reservationsWhat are driving conditions like around Custer?
Custer's local driving is genuinely easy: flat farmland, low traffic, and a straight shot to Interstate 5. Conditions get more interesting if you head east toward Mount Baker on State Route 542, a beautiful but winding two-lane mountain road with switchbacks at higher elevations, best driven slowly in larger RVs. Watch for fog on I-5 near the Custer Rest Area in early mornings, and expect heavier southbound traffic on Sunday afternoons returning from the border. Winter trips can bring rain, occasional snow at higher elevations, and slick bridges. WSDOT's real-time traffic and mountain pass reports are your best friend before you set out.
wsdot.com/travel/real-time/mountainpassesWhat amenities do campgrounds near Custer offer?
Campgrounds near Custer cover the full spectrum. Birch Bay State Park has a trailer dump station, potable water fills, flush restrooms, and 18 showers, with 20 sites offering water and electric hookups (no sewer at the site). Private parks like The Cedars RV Resort and Beachwood Resort in Birch Bay offer full 30/50-amp hookups, Wi-Fi, laundry, and pools. Most local parks have a dump station even if your site is dry. Pro tip: top off fresh water at your campground before you leave, the Mount Baker Highway has limited fill stations once you head east, and you'll want full tanks for boondocking near Glacier or Silver Lake Park.
parks.wa.gov/find-parks/state-parks/birch-bay-state-parkWhat's inside a typical RV rental from Custer?
Most RV rentals in Custer come stocked and trip-ready. Expect a full kitchen (fridge, stove, microwave, sink), a wet or dry bathroom with toilet and shower, sleeping for 2 to 8 depending on size, propane furnace, roof air conditioning, and seatbelted travel seats. Many hosts include linens, cookware, camp chairs, and outdoor mats; some upgrade with TVs, solar setups, generators, or Starlink Wi-Fi for working on the road. Campervan rentals in Custer (Class B) are cozier and easier to drive, while Class C motorhomes and travel trailers give families more space. Pro tip: check the listing's amenity list and message the host to confirm any must-haves before you book.
energy.gov/energysaver/recreational-vehiclesWhat add-ons and pickup options should I expect?
Hosts in Custer set their own add-ons, and the menu is generous. Common extras include generator use ($5 to $15 per night), propane top-offs ($30 to $50), bike racks, kayak racks, outdoor grills, bedding packages, and pet fees ($25 to $75 per stay). Most hosts offer pickup from their property in Custer or nearby Ferndale and Blaine, and many will deliver to your campsite for a per-mile fee. Mileage policies vary: some include 100 miles per day free, others bundle unlimited mileage. Pro tip: ask about a generator if you're heading to Birch Bay's standard (non-electric) loop, you'll want it for coffee mornings.
wdfw.wa.gov/places-to-goHow do payment and the security deposit work?
Payment for your RV rental in Custer is handled securely through RVezy at checkout, no cash or e-transfers to the host. You'll pay the trip total upfront by credit card, and the security deposit is pre-authorized (held, not charged) on your card shortly before pickup, typically ranging from $500 to $1,500 depending on the rig. As long as you return the RV in the agreed condition with the right fuel and tank levels, the hold is released within a few days of your trip ending. Pro tip: take date-stamped photos and a quick walkaround video at both pickup and drop-off, it's the simplest way to keep your deposit return smooth and stress-free.
help.rvezy.com/hc/en-us/articles/360038106214-How-the-security-deposit-worksHow should I prepare for cool, wet weather on a Custer RV trip?
Custer's maritime climate means rain is part of the charm, even in summer you can get a misty morning. The good news: nearly every RV rental in Custer comes with a propane furnace, and many hosts include shore-power adapters so you can plug into 30-amp or 50-amp hookups at parks like The Cedars RV Resort to run a space heater on chilly nights. For shoulder-season or winter trips (November through March, with highs in the low 40s), ask the host about heated holding tanks, tank-warmer pads, or skirting if you're staying put for several days. Pro tip: pack waterproof shoes and a lightweight rain jacket, you'll use them more than sunscreen.
