The Mount Whitney Trail is perhaps the most iconic and challenging hike in California, leading to the highest peak in the contiguous United States at 14,505 feet. This 22-mile round-trip hike requires significant preparation, including securing a permit, acclimatizing to the altitude, and packing adequate supplies. The trail begins at Whitney Portal and ascends over 6,000 feet, with steep switchbacks and rocky terrain. Hikers must contend with thin air and potential altitude sickness, making this trek both physically and mentally demanding. Despite the challenges, the panoramic views from the summit and the sense of accomplishment make it a bucket-list hike for many adventurers.
Half Dome – Yosemite National Park
Half Dome is one of Yosemite National Park’s most iconic landmarks and one of its most challenging hikes. This 14- to 16-mile round-trip trek requires hikers to ascend nearly 5,000 feet from the valley floor to the summit. The final ascent involves climbing the famous cable route, where hikers pull themselves up a sheer granite face using steel cables. This section is not for the faint of heart, requiring strength, nerve, and a head for heights. Permits are required to climb Half Dome, and preparation is key. The reward is a breathtaking 360-degree view of Yosemite Valley and the surrounding wilderness, a sight that makes the grueling effort worthwhile.
Rae Lakes Loop – Kings Canyon National Park
The Rae Lakes Loop is a challenging 41.4-mile circuit in Kings Canyon National Park that takes hikers through some of the park’s most stunning alpine scenery. The trail features over 7,000 feet of elevation gain, crossing high mountain passes such as Glen Pass at 11,978 feet. Hikers will encounter diverse landscapes, from lush meadows and crystal-clear lakes to rugged peaks and expansive forests. This multi-day hike requires endurance, proper gear, and backcountry experience. The pristine beauty of Rae Lakes and the surrounding High Sierra wilderness provides a truly rewarding experience for those who take on this demanding loop.
Telescope Peak – Death Valley National Park

Telescope Peak offers one of the most challenging hikes in Death Valley National Park, leading to the highest point in the Panamint Range at 11,043 feet. This 14-mile round-trip hike begins at Mahogany Flat Campground and involves a strenuous ascent of nearly 3,000 feet. The trail traverses diverse terrain, from desert landscapes to alpine forests, with panoramic views of Death Valley and the Sierra Nevada. The altitude and extreme temperature variations add to the difficulty, requiring careful planning and ample water supplies. The summit rewards hikers with unparalleled views of both the lowest and highest points in the contiguous United States—Badwater Basin and Mount Whitney.
Cactus to Clouds Trail – Mount San Jacinto State Park
The Cactus to Clouds Trail is known for its extreme elevation gain and is considered one of the toughest day hikes in the United States. This grueling 21-mile hike starts in Palm Springs at an elevation of 475 feet and ascends over 10,000 feet to the summit of Mount San Jacinto. The first part of the trail, up to the tram station, is particularly challenging due to the steep and exposed terrain. From the tram station, hikers continue to the summit, where they face further elevation gain and often snowy conditions. Proper preparation, including acclimatization and hydration, is essential for tackling this strenuous hike. The breathtaking views from the summit make the arduous journey a memorable achievement.
Clouds Rest – Yosemite National Park
Clouds Rest offers a challenging alternative to Half Dome, with fewer crowds but equally spectacular views. This 14.5-mile round-trip hike features an elevation gain of 1,775 feet, culminating at 9,926 feet. The trail provides diverse scenery, including forests, granite slabs, and exposed ridges. The final ascent along a narrow, rocky ridge can be intimidating, but the panoramic views of Yosemite Valley, Half Dome, and the Sierra Nevada are a rewarding payoff. Clouds Rest requires physical stamina and mental fortitude, making it a challenging yet exhilarating hike for those seeking a less crowded but equally rewarding Yosemite adventure.
Mount Langley – Sequoia National Park

Mount Langley is one of California’s lesser-known 14ers, offering a challenging hike with breathtaking views. The 22-mile round-trip trail starts at Cottonwood Lakes and ascends over 6,000 feet to the summit at 14,026 feet. The hike involves navigating rocky terrain, steep switchbacks, and potential snowfields, requiring physical endurance and proper acclimatization to the high altitude. The summit rewards hikers with panoramic views of the Eastern Sierra and the surrounding wilderness. Due to its remote location, Mount Langley sees fewer hikers, providing a more solitary and immersive backcountry experience.
High Sierra Trail – Sequoia National Park
The High Sierra Trail is a demanding 72-mile trek from Sequoia National Park’s Crescent Meadow to Mount Whitney. This multi-day hike traverses the heart of the Sierra Nevada, featuring diverse landscapes, including alpine meadows, rugged peaks, and pristine lakes. Hikers must contend with significant elevation changes, crossing several high mountain passes, including Kaweah Gap and Trail Crest at 13,600 feet. Proper preparation, including securing permits, packing adequate supplies, and planning for variable weather conditions, is essential. The breathtaking scenery and sense of accomplishment upon completing this challenging trek make it a truly epic adventure for experienced hikers.
These hikes represent some of the most challenging and rewarding trails in California’s national parks. Each offers a unique combination of physical demands, stunning scenery, and a deep sense of achievement for those who undertake them.
