America's 10 Most Dangerous Hikes

Like your life and limbs intact? Then you'd better get skilled before visiting these trails.

Horseshoe Canyon, Utah

Horseshoe Canyon, formerly known as Barrier Canyon, is in a remote area west of the Green River and north of the Canyonlands National Park Maze District in Utah, USA. It is known for its collection of Barrier Canyon Style (BCS) rock art, including both pictographs and petroglyphs, which was first recognized as a unique style here. A portion of Horseshoe Canyon containing The Great Gallery is part of a detached unit of Canyonlands National Park. The Horseshoe Canyon Unit was added to the park in 1971 in an attempt to preserve and protect the rock art found along much of its length.

Bright Angel Trail, Grand Canyon, AZ

The trail originates on the south rim of Grand Canyon and descends 4380 feet in elevation to the Colorado River. It has an average grade of 10% along its entire length. At trail's end, the River Trail continues another 2 miles to the Bright Angel Campground and Phantom Ranch. These two trails combined are the most common method used to access Phantom Ranch by hikers and mules.

There are two trails that cross or join this trail. The first being the Tonto Trail at Indian Gardens which leads towards the Monument Use Area to the west (the east leads to the South Kaibab Trail 4.7 miles (7.6 km) from the junction), and the River Trail which officially begins when the Bright Angel Trail reaches the Colorado River at the River Resthouse, although some consider that the Bright Angel Trail officially ends after crossing the Colorado River at the Silver Bridge.

Pikes Peak, Colorado

Pikes Peak is a mountain in the Front Range of the Rocky Mountains, 10 miles (16 km) west of Colorado Springs, Colorado, in El Paso County. It is named for Zebulon Pike, an explorer who led an expedition to the southern Colorado area in 1806. At 14,115 feet (4,302 m)[1], it is one of Colorado's 54 fourteeners. Drivers race up the mountain in a famous annual race called the Pikes Peak International Hill Climb. The peak is also the annual site of the Pikes Peak Marathon and Ascent foot races on the Barr Trail. An upper portion of Pikes Peak is a federally designated National Historic Landmark.

Mount Washington, New Hampshire

Mount Washington is the highest peak in the Northeastern United States at 6,288 ft (1,917 m). It is famous for its dangerously erratic weather, holding the record for the highest wind gust directly measured at the Earth's surface, at 231 mph (372 km/h) on the afternoon of April 12, 1934. It was known as Agiocochook, or "home of the Great Spirit", before European settlers arrived.

The mountain is located in the Presidential Range of the White Mountains, in Coos County, New Hampshire. It is the third highest state high point in the eastern U.S. and the most prominent peak in the Eastern United States.

While nearly the whole mountain is in the White Mountain National Forest, an area of 59 acres (0.24 km2) surrounding and including the summit is occupied by Mount Washington State Park.

Mount Rainier, Washington

Mount Rainier is an active stratovolcano (also known as a composite volcano) in Pierce County, Washington, located 54 miles (87 km) southeast of Seattle. It towers over the Cascade Range as the most prominent mountain in the contiguous United States and Cascade Volcanic Arc at 14,411 feet (4,392 m).

The mountain and the surrounding area are protected within Mount Rainier National Park. With 26 major glaciers and 35 square miles (91 km2) of permanent snowfields and glaciers, Mount Rainier is the most heavily glaciated peak in the lower 48 states. The summit is topped by two volcanic craters, each over 1,000 feet (300 m) in diameter with the larger east crater overlapping the west crater. Geothermal heat from the volcano keeps areas of both crater rims free of snow and ice, and has formed the world's largest volcanic glacier cave network within the ice-filled craters. A small crater lake about 130 by 30 feet (40 m × 9.1 m) in size and 16 feet (5 m) deep, the highest in North America with a surface elevation of 14,203 feet (4,329 m), occupies the lowest portion of the west crater below more than 100 feet (30 m) of ice and is accessible only via the caves.

Mount Rainier has a topographic prominence of 13,211 feet (4,027 m), greater than that of K2 (13,189 feet (4,020 m)). On clear days it dominates the southeastern horizon in most of the Seattle-Tacoma-Bellevue metropolitan area to such an extent that residents sometimes refer to it simply as "the Mountain." On days of exceptional clarity, it can also be seen from as far away as Portland, Oregon, and Victoria, British Columbia.

Huckleberry Mountain, MT

The Hike In Glacier National Park, you could spit and hit a grizzly. Well, almost–the park features the highest bear density in the Lower 48. One recent study counted 563 individuals, and researchers suspect the actual population may be even higher. That's .35 bears per square mile–or one bear within a one-mile radius of every backcountry campsite. Come summer and fall, aptly named Huckleberry Mountain becomes a magnet for hungry grizzlies, which are commonly found foraging the plump, purple fruit that ripens along the Apgar/Huckleberry Lookout Trail. "Large numbers of bears congregate there when there's a bumper crop," says supervisory ranger Gary Moses. In high huckleberry season, rangers often close the trail to dayhiking–but backpackers may still complete overnight trips in the area.

Kalalau Trail, Hawaii

The Kalalau Trail is a trail along the Nā Pali Coast of the island of Kauai in the state of Hawaii. The trail is very strenuous and runs approximately 11 miles (18 km) along the island's north shore from Keʻe Beach to the Kalalau Valley. An experienced, very fit hiker can complete the trail in about a day, but most people require two days and will camp along the trail.

The trail is located in the Nā Pali Coast State Park and access is controlled in the cause of conservation. A limited number of permits are issued for camping in Kalalau Valley every year. In spite of the efforts of the state of Hawaiʻi, many people hike the trail without paying money to the State Park office.

The trail starts on the north shore of the island, where the main highway ends at Keʻe Beach. The first two miles (3 km) of the trail are moderately strenuous and open to the public. This portion of the trail leads to Hanakapiai stream and beach. The trail beyond Hanakapiʻai is open only to those with camping permits.

The trail continues for approximately four miles to Hanakoa Valley, which is a hanging valley with no beach access. After Hanakoa, the trail turns more toward the dry side of the island. About five miles (8 km) later is Kalalau Valley, a large, flat-bottomed valley almost a mile across.

Buckskin Gulch, Utah

The Buckskin Gulch in southern Utah is one of the main tributaries of the Paria River, which is itself a major tributary of the Colorado River. It is the longest and deepest slot canyon in the southwest United States and may very well be the longest in the world. As such it is one of the premier destinations for slot canyon hikers, and receives a high amount of foot traffic. At over 13 miles (21 km) in length it is often visited in conjunction with the longer Paria Canyon, although some prefer to make a long day trip out of the hike. With a distance of 20 miles (32 km), hiking this canyon in one day is do-able but not easy. Wire Pass, a short tributary to the Buckskin, is an ideal alternative for a short day hike that still takes hikers through the narrow, curving features that are the hallmark of slot canyons.

Great Smoky Mountains, Tennessee-North Carolina

The Great Smoky Mountains are a mountain range rising along the Tennessee-North Carolina border in the southeastern United States. They are a subrange of the Appalachian Mountains, and form part of the Blue Ridge Physiographic Province. The range is sometimes called the Smoky Mountains or the Smokey Mountains, and the name is commonly shortened to the Smokies. The Great Smokies are best known as the home of the Great Smoky Mountains National Park, which protects most of the range. The park was established in 1934, and with over 9 million visits per year, it is the most-visited national park in the United States.

Half Dome, California

Half Dome is a granite dome in Yosemite National Park, located in northeastern Mariposa County, California, at the eastern end of Yosemite Valley — possibly Yosemite's most familiar sight. The granite crest rises more than 4,737 ft (1,444 m) above the valley floor.
