1. Cactus to Clouds Trail – San Jacinto Peak
Starting from Palm Springs at 520 feet, this 21-mile trail ascends over 10,000 feet to San Jacinto Peak. It’s one of the steepest and most grueling hikes in the U.S., with extreme temperature variations and seasonal hazards like snow and ice. Summer heat can exceed 110°F, while early spring still has icy, dangerous conditions at higher elevations. Rescue operations are frequent due to heat-related incidents.
2. Half Dome – Yosemite National Park
The final 400-foot ascent involves a steep climb using steel cables. Since 1919, there have been 10 confirmed deaths on this section, with the latest fatality occurring in July 2024. Most accidents happen when the rock is wet, and hikers are advised to check the weather before attempting the summit.
3. Tenaya Canyon – Yosemite National Park
This route is notorious for its steep, polished granite walls and fast-moving water. Hiking here involves dangerous exposure to heights, mandatory swims, and slippery surfaces. The canyon has claimed lives due to its challenging conditions. Wikipedia

20. Mount Tom – Eastern Sierra
This relatively lesser-known peak in the Eastern Sierra can be deceptively dangerous due to its remote nature and rugged terrain. While the ascent is challenging and strenuous, what makes it particularly hazardous is the unpredictable weather and lack of easy access for rescue teams. The steep rock faces, narrow ridgelines, and frequent rockfall make it a trail that demands respect. Several hikers have encountered trouble here due to poor route-finding or sudden storms, and it’s not uncommon for people to become disoriented in the high-altitude environment.
Preparing for the Worst: A Survivalist’s Mindset
While these trails are undeniably breathtaking and offer unparalleled adventure, they also present very real and dangerous risks that should not be underestimated. As a survival prepper, I always approach these trails with the mindset that my life may depend on the gear I carry, my knowledge of the terrain, and my ability to make decisions under pressure. Here are some survival prepper tips that could very well save your life if you find yourself on one of these deadly hiking trails:
1. Know Your Limits
Don’t overestimate your abilities. These trails aren’t the places to push your boundaries. Many of these hikes require expert-level fitness, endurance, and mental toughness. If you’re not in peak physical condition, you might want to reconsider or choose a less challenging trail.
2. Weather Check
Weather can be your worst enemy, especially on California’s most deadly trails. Check forecasts not only for the day of your hike but for several days before. Some trails are in areas prone to sudden, severe weather changes—like Mount Whitney, where storms can brew quickly.
3. Proper Gear
Your gear can mean the difference between life and death. Waterproof clothing, layered outfits, emergency blankets, a first-aid kit, and adequate food and water are all necessities. I always recommend carrying more than you think you’ll need. A lightweight survival kit with fire-starting tools, an emergency whistle, and a headlamp can be lifesavers in an unexpected situation.
4. Water Management
Many of these trails, such as the Lost Coast Trail or Tenaya Canyon, lack reliable water sources. Carry enough water to last you the entire hike, and always bring a portable water filter or purification tablets in case you need to rely on streams or lakes.
5. Track Your Progress
There’s no shame in using a GPS device or a trail map. In remote areas, like the Rubicon Trail or Bishop Pass Trail, getting lost can be a death sentence. Many hikers underestimate the importance of navigation skills and end up in dangerous situations due to disorientation.
6. Tell Someone Your Plan
Before tackling one of these hikes, make sure someone knows your planned route and expected return time. Having a point of contact can be crucial if you get into trouble. I always make it a point to check in every 12-24 hours on long hikes to ensure that help can be dispatched if something goes wrong.
7. Altitude Awareness
Many of California’s deadliest hiking trails are in high-altitude areas, such as Mount Whitney or Mount Baldy. Altitude sickness can incapacitate you without warning. If you’re not accustomed to hiking at high elevations, take the time to acclimatize. This will give your body the time it needs to adjust to the reduced oxygen levels.
8. Know When to Turn Back
No matter how close you are to the summit, or how determined you are to complete the hike, always know when to turn back. The descent is often more dangerous than the ascent, and pushing too hard can lead to exhaustion, dehydration, or even fatal mistakes.
9. Safety in Numbers
Hiking with a partner is a good idea, especially on longer or more hazardous trails. If something goes wrong, having someone with you can make all the difference in the world. Additionally, if you’re inexperienced, consider hiking with someone who has more knowledge of the terrain.
10. Search and Rescue Awareness
Even in areas where Search and Rescue (SAR) teams are common, getting help isn’t always guaranteed. Many of the most perilous trails, like the Half Dome or Cactus to Clouds, are located in remote areas, and SAR operations can take hours or even days. Make sure you have the means to help yourself out of dangerous situations. Know how to use your gear effectively, and always err on the side of caution.
Conclusion: Respecting the Terrain
Hiking in California is a rite of passage for many outdoor enthusiasts, but it’s crucial to understand that not all trails are created equal. The rugged beauty of trails like Yosemite’s Half Dome, the Mount Whitney ascent, or the brutal climb up San Jacinto Peak may be alluring, but these routes should be taken seriously. Don’t let the call of adventure override your instinct to stay safe. With proper planning, gear, and mindset, you can experience the majesty of these trails without falling victim to their deadly challenges.
Remember: it’s not just about surviving the trail, but knowing when to turn back. No summit is worth risking your life for. Plan accordingly, prepare diligently, and always hike with respect for the unforgiving landscapes of California. Your life might depend on it.
