Yosemite National Park is renowned for its stunning landscapes, breathtaking waterfalls, and awe-inspiring granite formations. However, its beauty can be deceiving, as some of the park's trails are among the most dangerous in America. This comprehensive guide will take you through the most deadly hikes in Yosemite National Park, discussing the risks involved, tragic experiences, and essential tips for those daring enough to take on these challenging trails.

1. Half Dome

Overview

Half Dome is one of the most iconic rocks on the planet, and reaching its 8,836-foot summit is no easy feat. The Mist Trail to the top of Half Dome and back spans 16 miles, with a grueling 4,800-feet elevation gain and sections of wet and dangerous stairs. The most notorious part of the hike is the ascent up the cables, where hikers climb the last 400 feet to the summit without rock climbing equipment.

Tragic Experiences

Since Yosemite National Park was founded, the trail to the top of Half Dome has been the deadliest in the park. There have been more than 20 deaths on Half Dome itself, and this number jumps to over 60 when considering the trail leading up to it. The most common cause of death is slipping off the side of the ascent or descent in the cables section. Other fatalities include heart attacks while climbing the cables, lightning strikes, failed base jumps, climbing accidents, and even suicides.

In 2019, 29-year-old hiker Danielle Burnett tragically fell off the cable section on Half Dome, falling to her death. According to witnesses, Burnett began to slip on the somewhat wet rock, sliding past other hikers before falling 500 feet off the side of the rock.

Tips for the Journey

Despite the dangers of the hike, thousands of people reach the summit each year without incident. However, hikers should consider their conditioning and the weather before attempting the trek. The hike should only be done between late May and early October when the cables are up. Any moisture on the rock wall can make it very slippery and dangerous. In fact, most deaths on the cable section occur when hikers slip down the rock due to moisture or poor shoe grip.

2. Upper Yosemite Falls

Overview

The Upper Yosemite Falls Trail offers a challenging hike to the tallest waterfall in North America, with a total elevation gain of 3,018 feet over 4.2 miles. The trail is crowded and can be slippery during peak flow season, making it a demanding experience for even the most seasoned hikers.

Additional Challenges

For those seeking an extra challenge, continue an additional mile from the top of Yosemite Falls to Yosemite Point, a viewing spot with great views of Half Dome and the High Sierra.

3. Mist Trail

Overview

The Mist Trail is a 3-mile out-and-back hike with a 1,909-foot elevation gain, ascending two great waterfalls – Vernal Falls and Nevada Falls. Known for its spray, the trail can be slippery and treacherous, especially during peak flow season.

Gateway to Other Trails

The Mist Trail serves as a gateway to numerous other Yosemite hiking objectives, including Half Dome, Clouds Rest, and the John Muir Trail. Conquering the Mist Trail is a prerequisite for those seeking to experience these more challenging hikes.

4. Four Mile Trail & Panorama Trail Loop

Overview

The Four Mile Trail climbs 3,200 feet from the Yosemite Valley floor to Glacier Point over 4.6 miles, offering consistent views of El Capitan, Yosemite Falls, Half Dome, Royal Arches, The Sentinel, and Tenaya Canyon. The return journey via the 8.5-mile Panorama Trail descends into the steep Ilillouette Gorge before passing Nevada Fall and Vernal Fall. This loop is considered one of the most challenging hikes in Yosemite National Park.

Tips for Hikers

This hike is best suited for those in top physical condition and requires careful planning, including timing and supplies, to complete in a single day.

5. Clouds Rest

Overview

With a 14.5-mile round trip and a 1,775-foot elevation gain, Clouds Rest is considered one of the toughest hikes in Yosemite. The trail offers 360-degree views of Tenaya Canyon, Little Yosemite Valley, and Half Dome from its knife's edge granite summit.

Considerations

The biggest considerations when undertaking Clouds Rest are time and water. Bring plenty of both, and be prepared for a challenging day on the trail.

6. Mt. Dana

Overview

Located near the East Entrance of Yosemite, Mt. Dana is the second highest peak in the park, standing at 13,061 feet. The 6-mile round trip hike and 2,906-foot elevation gain make it a unique challenge, offering beautiful vistas and seasonal wildflowers.

High Elevation Concerns

The biggest consideration for Mt. Dana is elevation. Give yourself time to acclimate, and drink plenty of water before, during, and after the hike. If you experience symptoms of altitude sickness, head back downhill immediately.

7. Chilnualna Falls

Overview

Located in the Wawona/Yosemite South section of the park, the Chilnualna Falls trail is an 8.2-mile round trip hike with a 2,400-foot elevation gain. The trail leads hikers past a series of falls and cascades, making it a challenging yet rewarding experience.
