National parks draw millions each year, offering adventure, but with that comes inherent risks. While these breathtaking landscapes captivate us, they also conceal the dangers that nature can unexpectedly present.
Throughout history, national parks have seen numerous fatal incidents, from falls and drownings to attacks by wildlife and other mishaps. These events have deeply affected the families and loved ones of those lost.
It's vital to remember that such fatalities, though tragic, are exceedingly rare. Every year, millions explore national parks safely. These destinations are typically secure and enjoyable. Still, visitors must remain vigilant and heed the risks of outdoor pursuits, following guidelines and warnings to stay safe.
Let’s delve into ten chilling and unfortunate deaths in national parks, the events leading to each one, and the valuable lessons they offer. Armed with this knowledge, you’ll be better prepared for your next adventure in these extraordinary national parks.
10. A Fatal Fall from Half Dome, Yosemite National Park

Half Dome, one of the most recognizable landmarks in Yosemite National Park, witnessed a tragic incident when Danielle Burnett, a 29-year-old woman, lost her footing while hiking and fell over 500 feet (152 meters) to her death. She was tackling the steep final section of Half Dome, a difficult ascent that involves using metal cables to ascend the challenging granite slope.
Danielle's heartbreaking death highlights the critical need for proper safety precautions in national parks. The Half Dome cables have long been considered a dangerous stretch for hikers. Her death marks at least the 12th fatality on this climb.
Over the years, numerous safety measures have been introduced to enhance the protection of climbers. These include cables along the route with the suggestion to use a safety harness, though it's not mandatory. Wooden beams have also been installed to provide support and offer hikers opportunities to rest. Additionally, the daily number of permits has been capped to limit the number of hikers on the trail at any given time.
9. Grizzly Bear Attack, Glacier National Park

Glacier National Park, located in Montana, is a stunning natural wonder that attracts millions of visitors each year. Its expansive trails, panoramic views, and majestic wildlife are among the park's many draws. However, the tragic incident we discuss here serves as a stark reminder of the potential dangers posed by wild animals.
Brad Treat, a 38-year-old U.S. Forest Service officer, was mountain biking with a friend when he unexpectedly encountered a grizzly bear. The sudden collision sent him flying from his bike, where he was mauled by the bear while his friend went to find help.
Though such incidents are uncommon, they highlight the need for caution when interacting with wildlife in national parks. Visitors should always remain vigilant and prepared for unexpected animal encounters. If you come across a bear, the Forest Service recommends the following actions:
- Remain calm and speak to the bear while slowly raising your arms
- Pick up small children
- Try to appear as large as possible
- Never run or attempt to climb trees
- Do not mimic prey behavior
- Allow the bear an escape route and slowly move away
8. A Fatal Fall from Angel's Landing, Zion National Park

Angel's Landing offers breathtaking vistas, but it is also recognized as one of the most hazardous trails in Zion National Park. The route features steep cliffs, narrow passages, and sharp inclines, demanding hikers to rely on chains for support.
Despite its dangers, Angel’s Landing remains a favorite hiking destination in Utah's Zion National Park. Over the years, several fatalities have occurred on this trail, leading authorities to urge hikers to exercise caution or avoid it altogether if they lack experience.
One such tragic event took place in 2017 when Tate Volino, a 45-year-old man, lost his grip on the treacherous trail and plunged 1,000 feet (305 meters) to his death. Incidents like this emphasize the critical need for hikers to assess their limits and follow safety protocols in national parks.
7. Flash Flood, Zion National Park

Flash floods are a frequent hazard in slot canyons and low-lying areas of national parks, particularly in Zion's narrows. Always check the weather forecast before embarking on any hike and be mindful of the park’s flash flood alert status. Being well-informed and prepared can make all the difference, as flash floods can strike with minimal warning.
In 2015, a group of seven hikers was swept away by a flash flood while exploring Keyhole Canyon. The storm, which unleashed over half an inch of rain within just one hour, caused the tragic incident. According to park authorities, all canyon hikers are given safety guidelines when they collect their permits. However, once deep within the canyon, there's no way to contact others if conditions rapidly change.
If you ever find yourself in an area susceptible to flooding, watch for these warning signs to stay as safe as possible.
- Formation of puddles
- Change in the water color of a flowing stream
- Increase in debris around an existing water source
- The sound of rushing water
While we all hope you never face such a situation, if you do notice the signs of a flash flood or are caught in one, knowing what to do could save your life. Your best chance is to seek higher ground. Though it’s ideal to exit the canyon, remember that outrunning a flash flood is often impossible. Other survival tips include:
- Avoid swimming or trying to cross the floodwaters
- If possible, steer clear of climbing rocks or ledges, as they could trap you or force you into deeper waters if the floodwaters rise.
- If you become stranded, stay where you are and allow the water levels to decrease.
6. Lightning Strike, Rocky Mountain National Park

Lightning strikes pose a significant risk in national parks, especially in high-altitude regions. Park officials recommend checking the weather forecast beforehand and avoiding hikes during thunderstorms or strong winds. If you find yourself in a thunderstorm, it's essential to take shelter in a low area or inside a building if one is nearby. Stay away from open spaces, tall trees, and metal objects, as these are prime targets for lightning strikes.
A tragic incident occurred in 2014 at Rocky Mountain National Park in Colorado, when a group was struck by lightning. The strike resulted in one fatality and seven injuries. Though it's fortunate that so many in the group survived, hikers and backpackers should always be mindful of the weather and plan their trips with care to avoid such dangerous situations.
5. Fall from the Grand Canyon, Grand Canyon National Park

In April 2018, a 35-year-old man tragically fell to his death while trying to take a photo near the edge of the Grand Canyon in Arizona. As he backed up to capture the shot, he lost his balance and plummeted 1,000 feet (305 meters). This incident is one of many fatal falls that have occurred at the Grand Canyon over the years.
The Grand Canyon is one of the most visited national parks in the United States, drawing millions of tourists each year. However, its steep cliffs and rugged landscape can be hazardous, particularly for those who get too close to the edge. On average, about a dozen people lose their lives in the park annually, with many of these fatalities resulting from accidental falls.
Visitors are advised to stick to marked trails, stay at a safe distance from the edge, and supervise children and pets closely at all times.
4. Drowning, Great Smoky Mountains National Park

During a hot summer hike, it might be tempting to take a refreshing dip in the park’s natural waters, but the National Park Service strongly advises against swimming or engaging in water activities as there are no designated swimming areas. In the event of an accident, help might take hours to arrive.
In 2022, a tragic drowning occurred near the Sinks in the Great Smoky Mountains National Park. A 61-year-old man fell into the water while kayaking and, unfortunately, did not resurface. Park officials were alerted to the incident soon after.
This heartbreaking event serves as a stark reminder of the risks associated with natural bodies of water, especially in areas with powerful currents or deep pools. Even subtle shifts in rocks and deceptively slow-moving currents can quickly turn a pleasant outing into a tragic incident. Park officials urge visitors to swim in pairs, avoid jumping or diving from high cliffs, and always use proper safety equipment.
3. Fallen Tree, Great Smoky Mountains National Park

While this type of accident is exceedingly rare, the death of a seven-year-old girl makes it even more tragic.
In July 2022, park rangers were called to the Great Smoky Mountains National Park shortly after midnight. A father was camping with his three daughters when a red maple tree, 2 feet wide (0.6 meters), crashed onto their tent, killing his seven-year-old daughter. Fortunately, the rest of the family remained physically unharmed.
Though investigators were unsure why the tree fell, they confirmed that this was the first fatality in the park's history caused by a tree falling on a tent.
2. Heatstroke, Joshua Tree National Park

In 2018, a hiker tragically lost their life to heatstroke while trekking through Joshua Tree National Park in the scorching California desert. This serves as a serious concern when exploring the park, as temperatures can soar beyond 100°F (37.8°C).
This unfortunate event underscores the peril of hiking in extreme heat, especially in dry, desert environments like Joshua Tree National Park. To avoid heatstroke while hiking, it’s crucial to stay hydrated by drinking ample amounts of water and electrolyte-rich beverages like sports drinks. Wearing light, breathable clothing and a wide-brimmed hat also offers protection against heat exhaustion.
If someone begins exhibiting signs of heatstroke, such as dizziness, confusion, or a rapid pulse, get them to a shaded area, offer cool water, and seek emergency medical help immediately. To prevent heatstroke, gradually acclimate to the environment by easing into physical activity and avoiding strenuous exercises during the hottest parts of the day.
1. Plane Crash, Denali National Park

Denali National Park is famous for its untamed wilderness and breathtaking landscapes, but it also presents dangers for those who don’t exercise proper caution. Visitors are urged to adhere to park guidelines and stay aware of the risks associated with backcountry exploration and other outdoor activities.
In 2018, a tragic accident occurred when a small sightseeing plane, carrying a pilot and four passengers, crashed in Denali National Park. Unfortunately, all five individuals aboard were killed. What makes this incident even more heartbreaking is that although the crash site was initially located, rescue efforts were impossible. Following an earthquake in the region, part of the mountain collapsed, causing the crash site to be lost forever.
