National Park Service RV regulations — federal rules every visitor must know: the short answer
36 CFR Part 1 governs NPS administrative rules; 36 CFR Part 2 governs resource protection. Together they prohibit dispersed camping, restrict generator hours, regulate quiet hours, prohibit cannabis, and limit RV size at specific campgrounds.
- Designated campground only: 36 CFR §2.
- RV length limits: not every NPS campground publishes a maximum, and published maxima run well past 45 ft. Death Valley states that Sunset and Stovepipe Wells campgrounds have no RV length restriction and that Furnace Creek has sites up to 100 ft. Check the specific campground.
- Generator hours: Each NPS unit's superintendent compendium sets generator hours.
- Cannabis posture (federal Schedule I): Cannabis remains federally Schedule I.
- Wildlife distancing + food storage: 36 CFR §2.

36 CFR Part 1 governs NPS administrative rules; 36 CFR Part 2 governs resource protection. Together they prohibit dispersed camping, restrict generator hours, regulate quiet hours, prohibit cannabis, and limit RV size at specific campgrounds. We are NOT licensed legal advisors. Verify the cited statute or agency page before relying on a specific rule, and consult a licensed attorney in your jurisdiction for any legal question that affects your personal situation.
1. Designated campground only
The rule: 36 CFR 2.10 leaves camping to each park superintendent, who "may require permits, designate sites or areas, and establish conditions for camping" under 2.10(a), while 2.10(b)(10) prohibits "Camping outside of designated sites or areas." Designated areas count, not only numbered campsites: many units designate backcountry or dispersed zones, usually permit-only — Death Valley states that dispersed and backcountry camping "is permitted in some places within the park," and Big Bend, Canyonlands, Glacier and Grand Canyon run comparable backcountry programs. Read that unit's superintendent's compendium and backcountry page before you park, and never assume empty ground is legal.
What it means in practice: Book Recreation.gov 6 months ahead. Walk-up sites exist at many parks but fill by mid-morning.
- Specific federal land unit may have a superintendent's compendium that adds local restrictions.
- Tribal land adjacent to federal land operates under tribal jurisdiction — not federal.
2. RV size + length limits per campground
The rule: Not every NPS campground publishes a maximum RV length, and published maxima routinely run past 45 ft. Death Valley states that Sunset Campground and Stovepipe Wells Campground do not have RV length restrictions, and that Furnace Creek Campground has sites that can accommodate up to 100 ft in total length. Yellowstone's campground table lists RV + vehicle maximum lengths of 25 ft at Lewis Lake, 27 ft at Pebble Creek, 31 ft at Tower Fall, 35 ft at Indian Creek, 40 ft at Canyon, 50 ft at Grant Village, 60 ft at Bridge Bay and Madison, and 95 ft at Fishing Bridge RV Park. Yosemite publishes a maximum RV length of 40 feet and a maximum trailer length of 35 feet in Yosemite Valley, and states it does not enforce the length limits as long as the RV or trailer can fit on the parking pad in the site. Some sites remain inaccessible to rigs over 30 ft because of road geometry, so check the individual campground page for the site you intend to book.
What it means in practice: Verify the specific campground's max length BEFORE booking.
- Specific federal land unit may have a superintendent's compendium that adds local restrictions.
- Tribal land adjacent to federal land operates under tribal jurisdiction — not federal.
3. Generator hours
The rule: Generator hours come from each NPS unit's superintendent compendium under 36 CFR 1.5; 36 CFR 2.12 itself sets no hours, only a 60 dBA at 50 ft ceiling for an electric generating plant. Where a unit publishes windows the evening block runs 5 pm to 7 pm — Mount Rainier is 8 am to 10 am, noon to 2 pm and 5 pm to 7 pm; Yosemite and Joshua Tree are 7 am to 9 am, noon to 2 pm and 5 pm to 7 pm. Other units publish no windows at all: Death Valley allows generators 7 am to 7 pm, Great Smoky Mountains sets generator quiet hours 8 pm to 8 am, and Rocky Mountain applies its 10 pm to 6 am quiet hours to generators. Read your unit's compendium before you run one.
What it means in practice: Tighter than state parks. Solar + lithium-house-battery rigs sidestep entirely.
- Specific federal land unit may have a superintendent's compendium that adds local restrictions.
- Tribal land adjacent to federal land operates under tribal jurisdiction — not federal.
4. Cannabis posture (federal Schedule I)
The rule: Recreational cannabis remains federally Schedule I; since April 2026, marijuana in FDA-approved products or under a state medical license is Schedule III. Either way, possession without federal authorization is prohibited on NPS land (36 CFR 2.35), and all federal land enforces federal law regardless of state legalization.
What it means in practice: Do not bring cannabis onto any NPS unit even in CO / CA / NV / etc.
- Specific federal land unit may have a superintendent's compendium that adds local restrictions.
- Tribal land adjacent to federal land operates under tribal jurisdiction — not federal.
5. Wildlife distancing + food storage
The rule: 36 CFR §2.2 — feeding wildlife is prohibited. Bear-country parks require hard-sided food storage (RV qualifies; cooler does not).
What it means in practice: Keep coolers and food locked inside the RV at all times in bear country (Glacier, Yellowstone, Sequoia).
- Specific federal land unit may have a superintendent's compendium that adds local restrictions.
- Tribal land adjacent to federal land operates under tribal jurisdiction — not federal.
Enforcement reality
Federal enforcement of these rules happens at federal-land entry stations (NPS gates, BLM patrols, USFS rangers, USACE locks), at international borders (CBP processing), and via federal court for serious violations of statute. Day-to-day enforcement is typically courteous and educational on first contact; repeat violators or commercial-scale violations escalate quickly. Federal officers carry their own statutory citation authority distinct from local police; a federal citation cannot be 'fixed' through state court channels. Routine encounters at NPS visitor centers, BLM field offices, and USFS ranger districts are educational opportunities — officers prefer to issue warnings + correct conduct, especially when the visitor demonstrates good faith.
Typical fines: Federal misdemeanors typically $100-5,000 per violation; serious violations escalate to federal felony with possible imprisonment. Civil compromise of forfeiture (vehicle, equipment, wildlife) can stack on top of the criminal penalty.
- Federal violations may be reported to your home-state DMV via Driver License Compact for traffic-adjacent infractions.
- Civil + criminal penalties stack for repeated or willful violations.
- Federal land-management agencies maintain visitor-history records that affect future permit eligibility.
- A federal misdemeanor conviction may affect employment, security clearances, and firearm rights in some contexts.
Foreign visitor notes
Foreign visitors are subject to federal law identically to US citizens. Bring a valid passport, your home-country driver license, and an International Driving Permit (IDP) issued in your home country before arrival. The rental vendor's onboard documentation typically satisfies state-level operator competency, but federal officers can request your federal-immigration status documents (passport + I-94) at any federal land unit.
Border crossings into the US (from Canada or Mexico) require CBP declaration of every person, every item, and every vehicle. Cannabis cannot cross either border legally regardless of state or province legalization. Firearms require pre-clearance both directions. Bear spray, certain food products, and some plants are restricted.
Foreign visitors should also be aware that federal-land rules apply identically regardless of language proficiency. Major NPS visitor centers offer multilingual handouts (typically Spanish, French, German, Japanese, Mandarin) but interior trail signage is English-only at most units. Download the official park map in your preferred language before arrival.

Cultural + accessibility notes
Tribal sovereignty
Federal land managed by BLM, USFS, NPS is distinct from tribal land. Tribal land operates under tribal sovereignty and the relevant tribal nation's own statutes — not federal land-management rules. Federal regulations do not automatically extend to tribal land; tribal regulations do not extend to federal land. Verify per-tribe rules separately, ideally with the tribal natural-resource office. Travel that involves a tribal land permit (Navajo Nation, Hopi, Pueblo nations, Wind River, etc.) is administered entirely by the tribe.
Lgbtq trans license
Travelers whose driver license name or gender marker does not match current presentation should carry passport (federal ID) alongside the state license. Federal land officers generally follow federal anti-discrimination guidance; state and county officers vary. For travel safety, document your federal-level identity proof carefully and know the closest federal court if a state-level interaction escalates.
Foreign visitor
Federal law applies identically to foreign visitors. There is no separate 'tourist exception' for federal regulations. Foreign visitors carry the same compliance obligations as US citizens for cannabis prohibition on federal land, firearms transport rules, wildlife transport, and border-crossing declarations. Language barriers are not a defense; bring an English-speaking traveling companion or a translation app to any federal-land interaction if your English is limited.
What Multi-agency federal doesn't tell you
What official federal pages typically do NOT publish in a single place: the practical interplay between federal rules and state law. A renter who reads only the state DMV page does not learn that federal rules override the state's cannabis legalization on federal land. A renter who reads only the federal page does not learn that the state's stricter inspection rule applies on top. The official content is technically correct in each silo but creates a false sense of complete information.
Federal regulations also rarely surface the rental-contract dimension. The rental vendor's contract terms layer ON TOP of federal + state law. All three apply simultaneously to a given booking. A vendor can prohibit conduct that federal law permits (e.g., off-pavement driving) and the contract controls between renter and vendor regardless of what the federal page says.
Finally, federal pages rarely surface the day-to-day enforcement reality. The statute says X is prohibited; the field officer issues warnings vs citations vs arrests based on context, demeanor, and the operational impact. Renters who understand this can navigate gray areas with significantly more confidence than the bare statute would suggest.
- Federal supremacy: Federal law preempts conflicting state law on federal land — including cannabis legality, firearm rules, drone operation.source
- State law layer: State law applies on state land + roads + most private property within the state; vendor contract layers on top.source
- Tribal sovereignty: Tribal land operates under tribal jurisdiction — neither state nor federal land-management rules automatically apply.source
- Vendor contract control: Rental vendor's contract terms can be stricter than statute; they control between the parties.source

NPS — 36 CFR Part 2 (Resource protection)Federal citations are handled in US District Court or a federal magistrate court near the violation. You typically have an option to pay the fine by mail (for minor infractions) or appear. Some categories require appearance. Failure to address can result in a federal warrant. Keep the citation paperwork and contact the issuing agency to confirm your options.
Congress.gov — federal statute lookupNo. Each agency operates under its own enabling statute and regulations. NPS is most restrictive (36 CFR Part 1 + 2 + park-specific superintendent compendium). USFS is in the middle (each forest's Travel Management Plan controls OHV; dispersed camping permitted in most). BLM is most permissive (default dispersed camping, 14-day stay limit).
