America’s national parks are treasured lands set aside for recreation, exploration, and preservation. As you plan your next camping trip, hike, or road trip through one of these natural wonders, you may wonder: can you smoke in a national park? I
t’s a fair question; the answer is more nuanced than a simple yes or no. This comprehensive guide will walk through the ins and outs of smoking policies across the U.S. National Park System.
We’ll cover the basics of federal regulations, specific rules in individual parks, where you can and cannot light up, and how to be a respectful smoker so everyone can enjoy these shared public spaces.
Are You Allowed to Smoke Tobacco in A National Park?
The short answer is no, you cannot smoke tobacco in a national park. The National Park Service (NPS) banned smoking in all national parks in 1983 to protect visitors, employees, and resources from the impacts of tobacco smoke.
This federal regulation applies to all NPS lands, including parks, monuments, battlefields, historic sites, lakeshores, seashores, recreation areas, and more. It prohibits the smoking of not just cigarettes but cigars, pipes, and all other tobacco products.

Why Does the NPS Have Such Strict Anti-Smoking Laws?
There are a few key reasons why the NPS prohibits smoking park-wide:
- Fire danger – Carelessly discarded cigarettes have ignited damaging fires in extremely flammable natural areas. Smoking and all tobacco use is a significant cause of human-caused wildfires.
- Secondhand smoke – Many parks aim to protect all visitors from exposure to secondhand tobacco smoke in recreation areas.
- Resource impact – Cigarette butts are non-biodegradable litter that harms wildlife and scenic landscapes. Tobacco also contains toxins that can leach into soils and waterways.
- Employee health – Park employees should not be subjected to smoke inhalation hazards in their workspace.
By banning smoking, the NPS helps fulfill its mission of preserving parks unimpaired for future generations. The smoke-free policy helps make the parks cleaner, safer, and more enjoyable.
So, What Does The No-Smoking Policy Entail?
The NPS smoking ban means tobacco use is prohibited in these areas:
- All buildings, facilities, restaurants, gift shops and visitor centers
- All lodging, including hotels, campgrounds, and backcountry campsites
- All vehicles and public transportation
- All outdoor areas like trails, picnic areas, scenic overlooks,
- All park beaches, swimming pools, boat docks and marinas
Those caught smoking in non-designated areas may face fines of $100-$5,000 and possible jail time. Smokers must go to designated smoking areas outside park boundaries to light up.

Are You Allowed to Smoke Marijuana in A National Park?
No, marijuana smoking and possession is illegal in national parks, even if it is allowed by state law. As federal lands, national parks fall under federal laws that prohibit marijuana.
The legal status of cannabis is complicated since some states have decriminalized or legalized marijuana. However, federal law and NPS regulations banning controlled substances override state law.
Rangers can charge those caught with marijuana with federal offenses. Penalties include fines up to $5,000 and six months imprisonment. So, it’s best not to bring marijuana into any national park.
Can You Vape In A National Park?
No, vaping and the use of electronic cigarettes are prohibited by the NPS tobacco-free policy. The smoke-free rules apply to vaping devices like e-cigarettes, vape pens, and mods.
Although vapes don’t contain tobacco, the NPS bans them for emitting secondhand vapor, including chemicals, and resembling smoking mannerisms that can trigger former smokers.
Those caught vaping in national parks face the same penalties as all other tobacco users. Vaping is only allowed in designated outdoor areas outside the park.
Some Popular National Parks and Their Smoking Laws
Here are some extra details on smoking and vaping policies for three of the most visited national parks:
Great Smoky Mountains National Park
As its name suggests, the Great Smoky Mountains were plagued by chronic smoke pollution. Thus, it vigorously enforces its no-smoking policy with fines over $100 for first offenses. Smoking is permitted outside the park on nearby roads, not within park boundaries.
Yellowstone National Park
Being an explosive area, Yellowstone prohibits smoking or vaping anywhere except designated areas like parking lots. Up to 80% of wildfires are caused by human activity like cigarettes.
Yosemite National Park
Yosemite does not allow smoking or vaping in all lodgings, campsites, trails, buildings, public transportation, or outdoor areas. There are designated smoking spots outside the park.

Conclusion
Smoking tobacco, marijuana, or vaping is prohibited inside all national parks by the National Park Service.
This stringent smoke-free policy aims to eliminate fire danger, secondhand smoke, litter, and employee health impacts for an improved visitor experience.
Although you cannot smoke within park premises, there are designated smoking areas outside park boundaries by state and local laws. When visiting a national park, it’s essential to fully comply with the tobacco-free regulations or risk facing civil penalties.
