14 National Parks With Rules That Sound Like They Were Written by a Prankster

1. Death Valley National Park

In Death Valley, you’re literally not allowed to give birth in the Saline Valley Hot Springs. Yes, someone decided that was a real problem. That absurd-sounding rule is seriously on the books to avoid biological—or medical—nightmares in that remote spot. They also ban using the pools when sick, require waterproof diapers for toddlers, and keep pets at least 50 feet away from those springs.

You might think this rule came from a stand‑up comedian, but trust me, it’s legal. It’s clearly intended to protect both human safety and the fragile ecosystem of the springs. The specificity—”no giving birth”—makes it feel like a prank, but it’s enforceable. So if you’re pregnant, stick to dry land when visiting Saline Valley.

2. Grand Canyon National Park

At Grand Canyon, you cannot bring your dog—or cat—on a rafting trip down the Colorado River. Not even your faith‑obedient feline. Service animals only. Not because someone disliked Vernon, your poodle, but because the rapids and environment are hazardous for pets and wildlife.

It’s a ban so explicit it sounds satirical: “No pets on your rafting trip.” But it reflects a thoughtful safety standard. They literally prohibit domestic animals below the rim except certified service animals. Makes you wonder if some folks tried taking Buster kayaking once and it ended poorly.

3. Shenandoah National Park

In Shenandoah, you must bury human waste at least three inches deep—and not within 10 yards of a trail or stream. Too shallow, and you’re breaking federal law. That rule ensures water supplies and hiking paths don’t get contaminated—and preserves the Leave No Trace ethos.

The rule’s tone is hilariously specific: “No burying less than three inches.” It’s clearly nerdy enough to make you chuckle. But it’s also enforced under federal sanitation regulations. It’s practical, detailed—and surprisingly rigid.

4. Yellowstone National Park

Yellowstone forbids walking on thermal features—no matter how tempting that hat on the steaming bacterial mat might be. Flip‑flops meet hot sulfuric crust, and that equals fines or jail. Tourists have actually been arrested for walking across the Grand Prismatic Spring mats to retrieve hats.

It sounds like a prankster made the sign, but the rule is deadly serious. You could permanently scar a colorful microbial mat—or your foot. Rangers and courts crack down because these are fragile, dangerous systems. So stay on the boardwalk, folks.

5. Joshua Tree National Park

Joshua Tree bans all balloons unless you have a permit—yes, even water balloons or helium balloons. It’s because they’re considered litter and a hazard to wildlife, or fire risk in that desert environment. No whimsy allowed without prior approval.

It feels absurd—balloons in a national park? But the rule is real. It’s aimed at preventing ingestion by animals or spark‑igniting windblown debris. So leave the piñata at home unless you cleared it with park management.

6. All National Parks: No Teasing Animals While They Breed

Animalia Bio

It’s federally illegal to tease, scare, feed, or harass animals that are nesting, breeding, or resting. So no catcall to a bison giving birth. It’s a broad rule so oddly phrased it sounds like an animal‑rights improv session.

Yet “teasing” is specifically mentioned in federal wildlife statutes. It’s designed to protect wildlife during sensitive phases. The rule is enforceable across every park. You might laugh, but disturbing mating elk could get you cited.

7. All National Parks: No Swearing or Obscene Gestures

Cursing, obscene speech, or gestures (like flipping the bird) are prohibited—under disorderly‑conduct laws that apply on federal land. Yes, your profanity could land you in hot water. It’s weird to think what feels like a harmless rant could be illegal.

This rule sounds like a Victorian joke—but it’s embedded in federal codes tied to public alarm or obscene acts. Park rangers technically could cite you for foul language. So maybe save the marine biology similes for your lodge back home.

8. All National Parks: Don’t Build Cairns or Disturb Existing Ones

Adding or moving rock piles (cairns) is forbidden since parks use them for critical trail navigation. Helps keep future hikers from going off course. Building your own spa tower is apparently illegal.

The rule sounds like silly OCD, but it’s there to prevent confusion or harm. Random cairns can mislead rescue teams or hikers. It protects both you—and the integrity of navigation systems in remote terrain.

9. All National Parks: No Drones or Hovercraft

Flying drones—or operating hovercraft—is banned outright unless explicitly pre‑approved for filming. So no buzzing above Yosemite’s cliffs taking cinematic footage unless you asked nicely first. It’s abrupt, but intended to protect noise‑sensitive wildlife and visitor experience.

That rule feels like satire: “No drones, period.” Yet it’s official NPS policy from 2014 onward. Enforced nationwide. Wildlife disturbance, privacy concerns, accidents—all reasons the rule exists.

10. All National Parks: Don’t Touch Dead Fish—or Other Dead Wildlife

You aren’t allowed to handle or disturb dead fish or carcasses you find. Gross, but crucial—rotting animals can spread disease and signals disturbances in the ecosystem. If you spot a dead fish, you’re supposed to report it to a ranger instead of pawing it.

It sounds over‑specific—like a trolling rule—but it’s legitimately enforced to protect public health. Some parks list it explicitly under wildlife protection regulations. So keep your mitts off dead trout, okay?

11. Zion National Park

Zion uses timed‑entry reservations to limit crowds—if you don’t get a slot, you’re stuck waiting in a holding pen outside. You can’t just roll up; you need a permit for some hikes like Angels Landing. It feels like Disneyland had a hand in drafting the rulebook.

It sounds like park access is being gamified, but it’s done to preserve the fragile trails and reduce wait‑line chaos. It’s enforceable—you will be turned away without a reservation. Civic amusement park vibes with canyon views.

12. Glacier National Park

Some areas of Glacier ban camping near lakeshores or streams—campfires must be within designated rings. You can’t just pitch up wherever you want—even if it seems picturesque. It’s about minimizing erosion and protecting wildlife water access.

It’s peculiarly specific: “no camping within X feet of water” and “no open pinecone fires.” It sounds like a prankster over‑thinking picnic etiquette. But rangers enforce it for safety and ecological reasons.

13. Everglades National Park

Pexels

Feeding or approaching alligators—even with permission—is illegal. You literally can’t lure a gator closer (to take a selfie). That rule sounds like reverse‑zoo instructions, but it’s deadly serious.

It’s federal law under wildlife harassment statutes. It’s meant to keep both you and the gators safe—and wild. Park signage warns: roadkill looks juicy but resist the impulse, or you may face prosecution.

14. Arches National Park

Climbing or walking on the natural arches is prohibited in many areas, especially sensitive sandstone fins. You can’t bounce across Landscape Arch for the ‘Gram. That was banned after Dean Potter’s stunt in 2006; hiking on arches can cause collapse or injury.

The rule sounds like “don’t walk on grandma’s antique” but applied to rocks. It’s enforceable and posted. If you disobey, you risk fines—and possibly triggering museum‑worthy rock implosions.
