1. North Cascades National Park, Washington
With its jagged peaks, steep cliffs, and remote wilderness, North Cascades is often dubbed the “American Alps.”
It’s also one of the least-visited parks, which means fewer rescues when things go wrong.
The most significant dangers here come from unpredictable weather, avalanches, and getting lost in the backcountry. If you’re hiking or climbing, always check the weather and carry a map—cell service is spotty, and trails can quickly become treacherous.
Survival tip: Stay on marked trails, and be prepared for sudden weather changes. Carry extra layers, even in summer!

2. Mount Rainier National Park, Washington
Mount Rainier, an active volcano, looms near Seattle and is a magnet for climbers. But don’t be fooled by its beauty—this park is dangerous, especially for those attempting to summit.
The combination of high altitude, crevasses, unpredictable weather, and volcanic hazards makes it one of the riskiest climbs in the U.S.
Survival tip: If you’re planning to summit, make sure you’re experienced or go with a guide. For hikers staying lower, stick to well-marked trails and avoid areas prone to landslides.

3. Sequoia National Park, California
Home to the world’s largest trees, Sequoia National Park also harbors its share of risks. The park’s elevation, rugged terrain, and remote areas mean hikers are at risk of altitude sickness, dehydration, and getting lost.
In the winter, heavy snowfall can trap visitors, making it nearly impossible to leave.
Survival tip: Acclimate to the altitude before setting out on long hikes, and always carry plenty of water. In winter, make sure to check road conditions and carry tire chains if needed.

4. Crater Lake National Park, Oregon
Crater Lake may seem peaceful, but the park’s high elevation, steep cliffs, and extreme winter weather pose serious threats.
Snowfall can reach up to 500 inches a year, and even in summer, the weather can shift from sunny to stormy in minutes. The rim’s steep drop-offs also make falls a major danger.
Survival tip: Stick to designated trails, and avoid standing too close to cliff edges—one wrong step can lead to a dangerous fall. Be prepared for rapidly changing weather.

5. Death Valley National Park, California
True to its name, Death Valley is one of the hottest places on Earth, with summer temperatures soaring above 120°F.
The extreme heat, lack of shade, and limited water sources make it incredibly dangerous for unprepared visitors. Dehydration, heatstroke, and vehicle breakdowns in remote areas are common hazards.
Survival tip: Avoid visiting in the peak of summer. Bring plenty of water, avoid strenuous activities during the hottest parts of the day, and ensure your vehicle is in top condition before venturing into the park.
