We all know that heading out into the wilderness can put your safety at risk, but Zion National Park has many undetected dangers that are easy to overlook.
Before you set off on your next trip to Utah’s desert oasis, you’ll want to know what you’re up against.
Today, we’re talking about seven hidden hazards in this stunning destination.
Let’s roll!
About Zion National Park
Established in 1919, Zion National Park was the first of its kind in Utah. However, Indigenous Americans had inhabited the land for around 8,000 years. Basketmaker Ancestral Puebloans and Parowan Fremonts lived among the soaring sandstone cliffs long before the National Park Service was on the horizon.
Located in the southwestern corner of the state, Zion spans multiple geographic districts. In addition to the desert landscape, you’ll also find woodlands, coniferous forests, and riparian zones. It’s no wonder millions of travelers make the pilgrimage here each year.
While you’re probably already familiar with the dangerous wildlife in Zion National Park, animal encounters aren’t the only threat to your safety here. Actually, many other factors pose greater risks than a mountain lion attack.
Don’t head off to see the towering geological formations without checking out these seven hazards you’ll face when you enter Zion.
In case you didn’t know: These Are the Most Dangerous Creatures in Zion National Park
#1 Dehydration and Heat Exhaustion
The desert climate of Zion National Park makes dehydration a top danger to visitors. In the height of summer, temperatures can reach 115 degrees Fahrenheit. It doesn’t help that shade can be hard to find.
Hiking is one of the most popular activities in the park. You’ll have over 90 miles of trails leading to captivating scenic overlooks, slot canyons, and beyond. But you need to be prepared for anything.
Even if you plan a short jaunt, pack twice as much water as you think you’ll drink. After all, one wrong turn could mean more hours under the burning sun. Having a backpack with a bladder is especially useful for these excursions. You can sip throughout the day and top it off at the five refill stations throughout the park.
It’s important to note that the natural water sources throughout Zion aren’t safe for drinking. Several species of cyanobacteria live in North Creek, La Verkin Creen, and the Virgin River. Filtration methods won’t remove them, so you must get your H20 from a safe source.
#2 Hypothermia
Excessive heat isn’t the only temperature to worry about. Even during the summer, nighttime temperatures can drop to near-freezing. In fact, you can see a difference of more than 30 degrees from day to night.
In 2022, a man and woman in their early 30s suffered from hypothermia while camping without adequate supplies. After attempting to hike out in the early morning, visitors located the man and helped him to safety. Sadly, his wife was found dead further up the trail.
This incident isn’t typical, but it’s a stark reminder that even young, healthy campers are susceptible to death from exposure.
Wearing plenty of layers can keep you comfortable during the day and warm at night, should you find yourself out in the elements after dark. Avoid getting wet unless you have a dry change of clothes handy.
Emergency blankets are lightweight, compact, and only cost a few bucks. Plus, they could save your life. Go ahead and throw one in your pack before your next outdoor adventure.
#3 Inclement Weather
While it’s often warm and sunny in Zion National Park, dangerous storms can appear out of nowhere. When this happens, the hydrophobic soil can’t absorb water, and flash floods occur.
This event is treacherous enough on its own, but it can be particularly deadly in the park’s slot canyons. In another 2022 incident, a hiker exploring The Narrows died after losing her footing during a flash flood. Her body was later found in the Virgin River.
It’s wise to check the weather before trekking out into the wilderness. If you see storms in the forecast, consider altering your plans. Backcountry campers should find a site on high ground away from low-lying areas where water could flow during a downpour.
Monsoon season takes place from July through September. This is when you’ll see the most heavy rain and lightning. However, unexpected storms can appear at any time, so keep your guard up year-round.
#4 Falls
Falls are the leading cause of death in America’s national parks, and Zion is no exception. In fact, over half of the destination’s 43 fatalities between 2010 and 2020 were due to these incidents.
Naturally, staggering cliffs and selfie-worthy vistas are a dangerous combination. Drop-offs range from a few hundred feet to several thousand. Focusing on your screen to capture the perfect shot could be deadly. Now, we’d never tell you not to take pictures of the majestic landscape. But we’ll advise you to keep your distance from any ledges and never step backward towards a steep cliff.
Additionally, avoid getting lost in the scenery when you hit the trails. Instead, watch where you step and stop frequently to take in the sights. After all, you’ll enjoy them more when you give them your full attention.
Remember to stick to established paths, as well. One wrong step could be your last.

#5 Rockfalls
Rockfalls are another of Zion National Park’s many dangers. These episodes are hard to predict, especially if you’re not a geologist. Causes range from precipitation to temperature changes and even seismic events. Of course, sometimes there’s no discernable source at all.
The park’s enormous cliff faces make these incidents even more treacherous.
The Weeping Rock area is particularly active. It actually closed down in 2020 after a rockslide dislodged over 400,000 cubic feet of debris. A geological survey later found that the zone still threatened the safety of Zion’s visitors.
Hikers caught a similar occurrence on film near the end of 2024.
Although it isn’t always an option, try to keep your distance from cliff faces when you’re in the canyons. If you see small rocks coming down the mountain, assume more are on the way and leave the area as quickly as possible. Finally, if you can’t escape the danger zone, shelter behind the largest boulder you can find until the movement stops.
#6 Dangerous Drivers
While deadly traffic accidents are rare in Zion National Park, drivers pose a significant danger to both animals and other visitors. Rangers get reports of collisions with mule deer and other wildlife every year.
The destination’s striking scenery is certainly tempting, but narrow, winding lanes and steep canyons provide plenty of reasons to keep your eyes on the road. Fortunately, you’ll find tons of overlooks to pull over and enjoy the sights.
In addition to wildlife and plunging cliffs, you’ll want to be especially careful around the Zion-Mount Carmel Tunnel. This has been the site of many major and minor accidents. Pedestrians and cyclists aren’t allowed, but Zion’s park rangers direct traffic here, and speeding drivers frequently threaten their safety.
Construction on the tunnel began in the 1920s. Needless to say, it wasn’t designed for modern-day RVs. If your rig measures more than 7’10” wide or 11’4” tall, you must get a permit to travel through.
#7 Animal-Transmitted Diseases
Our final danger in Zion National Park is one you can’t see with the naked eye. However, you can usually detect their carriers.
Many animals in the park carry diseases that can spread to humans. And it doesn’t take a bite to contract them. Diseases like bubonic plague and salmonella often live on the skin and fur of critters like deer and rodents. Petting them can put you at risk. Of course, you shouldn’t get close enough to touch the wildlife anyway, but this is another good reason to keep your distance.
Additionally, feces and urine can transmit illnesses like hantavirus, leptospirosis, and lymphocytic choriomeningitis. That’s why washing your hands before eating or touching your face is essential. You never know what kinds of creatures you’ve unknowingly come into contact with.
