Sold out? A legal plan B when the park campgrounds are full

Status: 2026-10-28. Stay limits and closures change. Check the agency pages in our sources before you go.

You set the alarm, you were online at 16:00, and Watchman was still gone in two minutes. It happens to many people. This page is the backup: legal places to sleep near each park on our five routes, and the rules that come with them. It is not a plan A. For a first fly-in trip in a rental RV, a booked site with water and a dump station beats a free spot on a dirt road. But knowing your options means one sold-out night won't ruin the trip.

Four kinds of plan B

What "dispersed camping" really means

Dispersed camping (also called boondocking) means camping on BLM or national forest land outside a developed campground. It's usually free and needs no booking [P1]. It also means you are completely on your own [P22]:

• No water, no toilet, no dump station, no trash bins, no host. Arrive with full fresh water and empty waste tanks, and take all your rubbish with you [P1][P22].
• Stay on designated roads. No driving off-road to find a spot. Use sites that already look used [P1].
• Toilets: use your RV toilet, a portable toilet or a waste bag. Around Moab this is mandatory [P1][P15].
• Distances: the BLM asks you not to camp within 1 mile of campgrounds, trailheads or picnic areas [P1]. Kaibab National Forest makes that a rule [P13].
• Fire: check current fire restrictions before you light anything [P1].
• Your rental contract may ban unpaved roads, and many dispersed areas are on dirt roads that turn to mud when wet [P2] [A — read your contract].

Stay limits and rules at a glance

On a road trip you rarely stay anywhere for 14 days. The rules that matter more are where you may camp and how far from the road [A].

Park by park

The parks in route order. "Private RV parks in …" means we know the towns have them, but we haven't checked any specific one [A]. For RV length limits inside the parks, see our size guide or the RV fit checker.

Zion (Springdale, Hurricane)

• In the park: Watchman and South campgrounds are "full almost every night" from mid-March to late November [P5].
• Plan B nearby: BLM Hurricane Cliffs east of Hurricane on SR-59/SR-9: 56 free designated sites, first-come, 14 days in 28 [P2]. BLM Red Cliffs and Baker Dam campgrounds near St. George, first-come [P4]. Sand Hollow State Park near Hurricane has RV sites with hookups, bookable up to four months ahead [P6][P7]. Private RV parks in Springdale and Hurricane [A].
• Watch out: "Not all sites are accessible to RVs or trailers" at Hurricane Cliffs, and roads can become impassable when wet [P2]. On March 23, 2026 the BLM decided to limit camping along much of SR-9 to designated areas and to build new campgrounds; no opening dates yet [P3]. The Red Cliffs road only takes vehicles under 12 ft high and wide [P4].
• Our take: In a rental RV, Sand Hollow or a private park in Springdale or Hurricane is the easier night. Use Hurricane Cliffs only if you arrive in daylight [A].

Bryce Canyon (Red Canyon, Tropic)

• In the park: The park campgrounds "can fill by noon on weekends May through October". No camping along the road or in pull-offs [P8].
• Plan B nearby: Red Canyon Campground (Dixie National Forest) on SR-12, about 4 miles east of US-89: 37 first-come sites, water, flush toilets, showers, a dump station ($10), $30 a night, late April to early October [P9]. Forest Service dispersed camping, by Dixie National Forest rules [P8][P10]. Kodachrome Basin State Park has RV sites with hookups [P7]. Private campgrounds in Bryce Canyon City and Tropic [P8][A].
• Watch out: Red Canyon takes no reservations, so arrive early [P9]. Dispersed: no more than 16 days within 10 miles of the same spot [P10].
• Our take: Red Canyon is a proper campground with water and a dump station, so it's the best first-come backup. Get there by late morning [P9][A].

Grand Canyon South Rim (Tusayan)

• In the park: There is no dispersed camping in the park. In 2026 Trailer Village is closed and Mather is dry camping only under Stage 4 water restrictions (details).
• Plan B nearby: Ten X (Tusayan-Montane), a Forest Service campground 2 miles south of Tusayan: 142 single and 18 double sites, 30 of them first-come, the rest on Recreation.gov; pull-through sites up to 35 ft. Recreation.gov says it "generally has open camping sites" [P11][P12]. Kaibab National Forest dispersed ("at-large") camping at least 0.25 mile from Highway 64 [P11]. Grand Canyon Camper Village in Tusayan, a commercial campground with hookups and coin showers, open seasonally [P11].
• Watch out: At Ten X, "RVs are not permitted to fill holding tanks", and there are no showers [P12]. The NPS page lists Ten X as open May 14 – September 30 and gives older site numbers than Recreation.gov, so check Recreation.gov for dates [P11][P12]. Kaibab dispersed: 14 days in 30, never within 1 mile of a developed site [P13].
• Our take: With Mather on dry camping, arrive with full water tanks wherever you stay. If you need power, Camper Village in Tusayan is the plan B [P11][A].

Arches and Canyonlands (Moab)

• In the park: Devils Garden (Arches) and The Needles (Canyonlands) fill early in season; Island in the Sky is first-come (details).
• Plan B nearby: The BLM runs more than 20 campgrounds around Moab, along SR-128 (Colorado River), SR-279, Kane Creek Road and SR-313 [P14][P15]. Most individual sites are first-come, $20 a night, with vault toilets but no water or electricity. Ken's Lake Loop A and Courthouse Rock sites 5 and 6 can be booked on Recreation.gov [P15]. Max RV length differs by campground: 40 ft at Goose Island, Big Bend, Horsethief and Ken's Lake, 18 ft at Drinks Canyon, no RVs at some [P15]. Dead Horse Point State Park has RV sites with partial hookups [P7]. Private RV parks in Moab [A].
• Watch out: First-come campgrounds near Moab "can fill by mid-morning during the busy season" [P14]. Many areas near Moab are closed to dispersed camping; where it's allowed, a portable toilet or waste bag is required [P15]. Flash floods: some canyons are "subject to extreme flooding" (details).
• Our take: Check the RV length in the BLM table before you drive out. For a first trip, Dead Horse Point or a Moab RV park is less stressful [P15][A].

Capitol Reef (Torrey)

• In the park: Fruita Campground has 71 sites, is reservation only and is full months ahead from mid-March through October. Cancelled sites can be booked the same day [P16].
• Plan B nearby: The NPS says the park "is surrounded by public lands where dispersed camping is allowed. Please use those areas when Fruita Campground is full" [P16]. Private RV parks in Torrey [A]. Even without a site, you can use Fruita's dump station and water fill for $5 [P16].
• Watch out: We have not checked the individual BLM and national forest areas around Capitol Reef for this guide, so we don't name spots. Ask at the visitor center [A].
• Our take: Keep refreshing Recreation.gov for same-day cancellations at Fruita; otherwise book a Torrey RV park as a backup [P16][A].

Yellowstone (West Yellowstone, Gardiner)

• In the park: No camping or overnight parking outside designated campgrounds. All campsites must be booked ahead, except Mammoth in winter [P17]. RV rental companies may not deliver or collect RVs inside the park [P17].
• Plan B nearby: There is no dispersed camping inside the park, so plan B means a gateway town [P17]. Baker's Hole (Custer Gallatin National Forest), 3 miles north of West Yellowstone: 73 sites, 33 with electricity, on Recreation.gov, May 1 – October 11, drinking water [P18]. Private RV parks in West Yellowstone and Gardiner [A].
• Watch out: Baker's Hole has no dump station and no showers [P18]. On the Gallatin, dispersed camping by vehicle is only allowed within 300 ft of routes marked for it on the Motor Vehicle Use Map [P18]. This is bear country, so store food in your RV [A].
• Our take: For Yellowstone, book a gateway-town RV park as soon as you know your dates, even before the park campgrounds. Long drives inside the park make a far-away plan B tiring [A].

Grand Teton (Jackson, Moran)

• In the park: Campgrounds are by reservation only. No sleeping in vehicles in pullouts or parking areas; overnight trailhead parking only with a backcountry permit [P19].
• Plan B nearby: Bridger-Teton National Forest: dispersed areas such as Toppings, Spread Creek and Pacific Creek [P20]. Grassy Lake Road (Rockefeller Parkway, between the two parks): 14 free first-come designated sites from mid-June, no water [P19]. Private RV parks in Jackson [A].
• Watch out: Bridger-Teton, Jackson district: no more than 5 days in 30 from May 1 to Labor Day, and not within ¼ mile of Curtis Canyon Campground [P20]. Grassy Lake Road sites have no water [P19].
• Our take: Spread Creek and Toppings fill up in summer. Have a Jackson RV park as your real plan B [A].

Rocky Mountain (Estes Park, Grand Lake)

• In the park: There are no same-day sales at the park's campgrounds [P21]. A campground booking includes your timed entry, so losing it costs you both [P21].
• Plan B nearby: Plan B means an RV park or campground in Estes Park or Grand Lake [A]. The surrounding Arapaho and Roosevelt National Forests allow dispersed camping only where the Motor Vehicle Use Map shows it (a dotted line beside the road), for up to 14 days in 30 [P22]. Colorado state parks are reservation only, up to six months ahead [P23].
• Watch out: We have not checked individual forest areas near Estes Park and Grand Lake for this guide, so we don't name spots. Without a site, you also need a timed-entry ticket for the next day (how it works).
• Our take: For a first trip, a private RV park in Estes Park is the realistic plan B. Book it when you book the timed entry [A].

Phoenix → Sedona → Grand Canyon: on the way north, Dead Horse Ranch State Park in Cottonwood can be booked up to 365 days ahead [P24]. Then see Grand Canyon above, and our Phoenix route.

When a private RV park is the only sensible plan B

Dispersed camping can be lovely. But on a first fly-in trip there are nights when we would only book a private RV park or a developed campground [A]:

• The first night after pickup. You are jet-lagged, the RV is new to you, and you still need to shop. Hookups and a short drive help [A].
• Arriving after dark. Finding a legal dispersed spot on an unknown dirt road at night is how people get stuck [A].
• Tanks full or empty. If the grey or black tank is full, or the fresh water is low, you need a dump station and water first [A].
• A long RV. Several BLM campgrounds near Moab take only 18–24 ft, some no RVs at all, and not every Hurricane Cliffs site fits an RV [P2][P15].
• Heat, storms or kids. Power for the air conditioning, a shower and a safe place to wait out a flash-flood warning matter more than saving the cost of a site [A].
• Yellowstone, Grand Teton and Rocky Mountain in summer. Dispersed areas fill up and have short limits; the towns are the real backup [P17][P20][P22][A].

Our fallback order for a sold-out night

1. Set alerts and keep checking Recreation.gov for cancellations, especially in the last few days. Fruita, for example, releases cancelled sites the same day [P16].
2. Book a refundable private RV park or state park now, so you have a bed. Cancel it if a park site turns up [P6][P23][P24][A].
3. On the day: aim for a first-come Forest Service or BLM campground by mid-morning [P9][P14][P15].
4. Dispersed camping last, in daylight, on a dry road your rental allows, with full water and empty tanks [P1][A].
