In desert parks like Big Bend, Death Valley and Joshua Tree, winter is the busy season. Big Bend's generally runs November through April and Joshua Tree's October to May, while Death Valley's winter camping season runs mid-October to mid-April. The snow parks in this guide keep one or a few campgrounds open to RVs, sometimes just a loop or two, with fewer services.

Rio Grande Village in Big Bend, Furnace Creek and Sunset in Death Valley, Mammoth in Yellowstone and Moraine Park in Rocky Mountain all take RVs in winter. The fine print is what catches people: booking can switch to first-come, first-served, some dump stations close and Mammoth's length limit drops to 30 feet. Dates and fees change yearly, so check each park's site before you commit.

Winter RV Campgrounds at a Glance

Individual sites within each campground vary.

What Changes When Parks Go to Winter Mode

Fewer sites. Yosemite's Upper Pines normally runs only its first two loops in winter (about 90 campsites), and Bryce Canyon's North Campground and Cades Cove in the Smokies open only part of theirs.

Dump stations vary. Bryce Canyon closes its North Campground dump station in winter, and Yellowstone says its dump stations may close when temperatures drop below freezing. Rocky Mountain keeps the Moraine Park dump and fresh-water fill available all winter. For no-hookup stays, the water and waste planning in the boondocking guide, written for BLM and national forest land, carries over.

Nobody shovels your site. Rocky Mountain and Grand Canyon's Mather Campground don't plow campsites, and both parks tell campers to pack a shovel.

A full campground doesn't mean a free pullout. Yosemite, Yellowstone and Joshua Tree all prohibit sleeping in your vehicle in pullouts or along the road, and Big Bend allows no boondocking. Line up a backup outside the park with this guide to finding RV parks and campgrounds.

Holidays still fill up. Big Bend is often full over Thanksgiving week and the Christmas season, and Yosemite can get very busy in late December and early January.

Generator rules vary. Texas Springs in Death Valley bans generators outright, so check each campground's posted hours.

Warm-Winter Parks Where Winter Is Peak Season

For a first winter park trip, start in the desert, where winter is the main season and the hard part is usually getting a site.

Big Bend National Park, Texas

Big Bend requires camping reservations. Base at Rio Grande Village. The concessioner-run Rio Grande Village RV Park has 25 full-hookup sites with a 38-foot maximum, and NPS calls it the only full-hookup camping in the park. Book it by phone; the number is on the NPS Big Bend camping page.

The NPS-run Rio Grande Village Campground runs at full capacity from November 1 through April 30, with no first-come, first-served sites. Low-hanging branches rule out some sites for tall or long rigs. Park records for Rio Grande Village average highs in the low 70s in December and January, with lows around 30°F.

Leave Chisos Basin to small rigs. The park recommends against motorhomes over 24 feet and trailers over about 20 feet because of the narrow, winding road and small, unlevel sites. From January 1 to April 15, stays are capped at 14 nights total in the park. For more Texas options, see the Texas RV camping guide.

Death Valley National Park, California

Furnace Creek is the one to book, open year-round with reservations for the mid-October to mid-April season up to six months ahead.

Every other NPS campground there is first-come, first-served, paid by card at an automated machine. Furnace Creek and Texas Springs are typically full on weekends and holidays, but Sunset, the park's largest campground, almost always has sites, even in peak season. Sunset and Texas Springs typically open in late fall and close in mid-April, and Texas Springs takes up to 35 feet in total length. The Death Valley camping page lists stay limits.

Joshua Tree National Park, California

Black Rock and Cottonwood matter most to RVers. Both take reservations on Recreation.gov, from the same day up to six months ahead, and they're the only campgrounds in the park with water and a dump station. The first-come, first-served campgrounds (Hidden Valley, White Tank and Belle) are full nearly every weekend from September to May, and White Tank and Hidden Valley cap combined length at 25 feet. A vehicle towing a trailer counts as two vehicles, and so does a motorhome towing a car. Sites usually allow two, and the park has no overflow parking.

Everglades National Park, Florida

The park's two drive-in campgrounds, Flamingo and Long Pine Key, are both reached from the Homestead entrance. Flamingo is the RV pick, with 65 large pull-through RV sites, 41 T-Loop sites with electrical hookups, solar-heated showers and two dump stations. Camping options expand around mid-November, and every site is open by mid-January. From December through April, reservations through Everglades Guest Services are highly recommended.

Long Pine Key is open seasonally from about November into spring, with water and a dump station. Check site length when you book either one; current details are on the Everglades camping page. Dry-season temperatures run from the low 50s to the upper 70s. For longer stays, see the Florida snowbird destinations guide or the Florida Keys RV camping guide.

Hot Springs National Park, Arkansas

Hot Springs is a different kind of winter stop. Gulpha Gorge Campground is open year-round and every site has full hookups, including 30- and 50-amp electric. Sites aren't pull-through, and the 60-foot maximum includes vehicle length. Reserve early; the campground fills quickly even in fall and winter.

Snow-Country Parks That Keep an RV Campground Open

Expect fewer open campgrounds, thinner services and roads that can close behind a storm.

Grand Canyon National Park, South Rim

Mather Campground is open all year with a 30-foot limit, and only a handful of its sites fit a 30-foot trailer. It takes reservations through its winter season (typically December 1 to February 28), and unbooked sites go first-come, first-served at the kiosk, one night at a time. Check that the dump and water fill at Camper Services is operating.

Trailer Village, the South Rim's full-hookup RV park, was listed as closed due to a water shortage at this writing, so check its status before counting on hookups. The Grand Canyon South vs North Rim guide covers the rest.

Zion National Park, Utah

Watchman Campground is open year-round, with reservations up to six months ahead, while South Campground closes for winter. The winter perk: in the non-shuttle season, usually December through February, private vehicles can drive the Zion Canyon Scenic Drive, apart from a holiday shuttle near the end of December. Rigs over the Zion-Mt. Carmel Highway limits can still reach Watchman through the South Entrance. The Zion RV camping guide has those limits and the shuttle details.

Yosemite National Park, California

Upper Pines is Yosemite's only campground on reservations all year. Wawona and Hodgdon Meadow switch to first-come, first-served in winter and can fill on holidays and weekends. Only Wawona's Loop A stays open then, and NPS lists the Wawona dump station as summer-only. The Valley and Wawona stay reachable by car all year, while Tioga Road and the Glacier Point road close, usually sometime in November. The Yosemite RV camping guide has the booking calendar and tunnel limits.

Great Smoky Mountains National Park, Tennessee and North Carolina

Cades Cove and Smokemont are the park's two year-round campgrounds. Neither has hookups or showers. In the off-season, Cades Cove opens only sites C1–12 and C26–61, and Smokemont keeps Loops A and B open along with its dump station. US 441 can close for snow, wind or other severe conditions. Smokemont's listing says it doesn't approve refunds for 441 closures. The Great Smoky Mountains RV camping guide covers drives and gateway towns.

Yellowstone National Park, Wyoming, Montana and Idaho

Mammoth Campground is the park's only year-round campground, first-come, first-served from mid-October into spring. From mid-October through April its length limit is 30 feet for RV plus vehicle, versus 45 feet from May to mid-October. Fishing Bridge RV Park, the only campground in the park with water, sewer and electrical hookups, is closed in winter.

The only road generally open year-round to regular vehicles runs from the North Entrance at Gardiner, Montana, through Mammoth and Tower Junction to Cooke City. Most other park roads close to regular vehicles from early November to late April. Daytime temperatures range from zero to 20°F, and sub-zero temperatures are common. Mammoth in winter suits RVers who already know how their rig handles deep cold.

Rocky Mountain National Park, Colorado

Moraine Park is the park's only winter campground, first-come, first-served from about mid-October, when summer reservations end. No campsite in the park has a water hookup, but the dump station and fresh-water fill stay available through winter. Pay with Recreation.gov's Scan and Pay or in person at the Beaver Meadows or Fall River entrances. Firewood and ice aren't sold in the campground in winter, so stock up in Estes Park.

Bryce Canyon, Arches and Capitol Reef

Bryce Canyon. North Campground is open year-round and reservable up to six months ahead, while Sunset Campground closes for winter. North's open loops shrink through the winter, and only Loops A and B take vehicles over 20 feet, so check what's open for your dates. Water at the campground is seasonal, so check whether it's on. The park sits at about 8,000 feet, and after snowstorms the main road closes temporarily at mile marker 3 while crews plow. The park's winter page has the details.

Arches. Devils Garden, the park's only campground, is first-come, first-served from November through February, paid with Scan and Pay or a self-registration envelope. Its roads and parking spurs are paved.

Capitol Reef. Fruita Campground is reservable year-round, and the park says there's less demand in winter and it's easy to secure a campsite. The dump and potable-water fill station is free with a campsite reservation, and from December 1 through February 28 the stay limit is 30 days instead of 14.

Two More Park Service Sites Worth a Winter Look

Neither of these is a national park. Both are National Park Service units with solid winter RV camping.

Organ Pipe Cactus National Monument, Arizona

Twin Peaks Campground has 174 RV sites, four of them large enough for RVs up to 45 feet. There are no hookups, but there's a dump-and-fill station, potable water and free solar-heated showers. Reserve on Recreation.gov up to six months ahead. Peak-season stays (November 15 to April 15) are limited to 21 consecutive days, and winter highs reach the 60s.

Padre Island National Seashore, Texas

All camping here is first-come, first-served year-round, with no reservations. Malaquite Campground's sites are 40 feet long and 18 feet wide, and campers self-register at the kiosk. The park has no electric or water hookups, but an RV dump and freshwater fill station sits next to the Malaquite entrance. Stays max out at 14 consecutive nights and 28 per calendar year. Winters are short and mild, with occasional strong cold fronts and gale-force winds. Rules are on the Padre Island camping page.

Roads, Chains and Length Limits

Measure the whole rig. Death Valley's Furnace Creek listing counts total length as vehicle plus trailer or RV plus tow vehicle. It warns that the park can cancel a reservation on arrival if the rig doesn't fit. Rocky Mountain adds the hitch. Compare your full setup length with every posted limit.

Some roads have their own limits. The Zion-Mt. Carmel Highway caps single vehicles at 35 feet 9 inches and combined vehicles at 50 feet. In the Smokies, motorhomes over 25 feet and passenger vehicles towing trailers are prohibited on year-round Wear Cove Road and on the seasonal Roaring Fork Motor Nature Trail and Rich Mountain Road.

Yosemite chains. Expect chain requirements from November through March. When chain controls are in effect, every vehicle must carry chains, four-wheel drive included. The snow-tire exemptions at the R-1 and R-2 levels cover only cars, pickups and SUVs weighing under 6,000 or 6,500 pounds that aren't towing, and a trailer with brakes needs chains on its braking wheels. Follow the chain maker's instructions and the park's tire chain page.

Colorado's traction law. The state's Vehicle Traction Law can be activated in Rocky Mountain at any time. When it is, a four-wheel-drive or all-wheel-drive vehicle needs mud-and-snow, mountain-snowflake or all-weather tires with at least 3/16-inch tread, or chains or an approved traction device. A two-wheel-drive vehicle needs chains or an approved traction device whatever tires it has, so carry them either way. The park's road status page explains how to get current conditions.

Pick the rig for the campground. Nearly every limit here favors a shorter setup. If you're still shopping, the RV sizing guide walks through the tradeoffs.

Before a Cold-Weather Trip

How an RV handles freezing nights depends on the unit. Check your owner's manual and labels for its cold-weather limits and its guidance on the furnace, LP system, holding tanks and carbon monoxide alarm, then have a qualified RV technician look over the heating and LP systems before you go. Winterizing for storage is a different job, covered in the RV winterization guide.

Not a U.S. citizen or resident, like many Canadian snowbirds? Bryce Canyon, Everglades, Grand Canyon, Rocky Mountain, Yellowstone, Yosemite and Zion charge nonresidents 16 and older an extra fee unless they hold an annual or America the Beautiful pass, so check the NPS passes page first. For U.S. citizens and permanent residents 62 and older, NPS says a Senior Pass may provide a 50 percent discount on some amenity fees such as camping, but generally not on concessioner fees like those at the Rio Grande Village RV Park.

The week you go, check each park's alerts and current conditions.

If a winter park trip has you thinking about a rig that fits more of these sites, the RV quiz can help narrow down a size. A local dealer can walk you through a specific unit's length, tank sizes and cold-weather equipment.
