More than 2,000 natural sandstone arches, many of them recognizable worldwide, are preserved in Utah's Arches National Park. Temperatures can reach triple digits in the summer and can drop to below freezing in the winter
Arches National Park, Utah
Upper and Lower Antelope Canyon
The Snake River flows through Grand Teton National Park, and the jagged Teton Range rises above the sage-covered valley floor. Daytime temperatures during summer months are frequently in the 70s and 80s, and afternoon thunderstorms are common.
Visitors watch the sun rise at 10,000 feet in Haleakala National Park in Maui, Hawaii. If weather permits, visitors at the top of the mountain can see three other Hawaiian islands.
Grand Canyon National Park is perhaps the most recognizable national park. Nearly 5 million visitors view the mile-deep gorge every year, formed in part by erosion from the Colorado River. The North and South rims are separated by a 10-mile-wide canyon
Yellowstone National Park, America's first national park, was established in 1872. The park spans parts of Wyoming, Montana and Idaho. Grizzly bears, wolves, bison and elk live in the park. It is well known for Old Faithful and other geothermal features.
Glaciers. Rainforests. Hiking trails. Mount Rainier National Park, located in Washington state, offers incredible scenery and a diverse ecology. The park aims to be carbon neutral by 2016.

Washington state's Olympic National Park offers visitors beaches on the Pacific Ocean, glacier-capped mountain peaks and everything in between. Keep the weather in mind when visiting, though, as roads and facilities can be affected by wind, rain and snow any time of year.
Sequoia and Kings Canyon
A woman stands among a grove of a Giant Sequoia trees in Sequoia National Park in Central California. The trees, which are native to California's Sierra Nevada Mountains, are the world's largest by volume, reaching heights of 275 feet and a ground level girth of 109 feet. The oldest known Giant Sequoia based on its ring count is 3,500 years old.
Alaska's Denali National Park spans 6 million acres and includes the 20,320-foot Mount McKinley, North America's tallest peak. Many park visitors try to catch a glimpse of the "big five" -- moose, caribou, Dall sheep, wolves and grizzly bea
Kenai Fjords National Park
The National Park Service considers the 8.2-mile round-trip on Harding Icefield Trail in Alaska's Kenai Fjords National Park to be strenuous, saying hikers gain about 1,000 feet of elevation with each mile.
California's Death Valley encompasses more than 3.3 million acres of desert wilderness. In 1849, a group of gold rush pioneers entered the Valley, thinking it was a shortcut to California. After barely surviving the trek across the area, they named the spot "Death Valley." In the 1880s, native peoples were pushed out by mining companies who sought the riches of gold, silver, and borax.
Bison graze in Wind Cave National Park in the southern Black Hills of South Dakota. Millions of bison were slaughtered by white hunters who pushed them to near-extinction by the late 1800s. Recovery programs have brought the bison numbers up to nearly 250,000

America's Lesser-Known National Parks
Great Sand Dunes National Park and Preserve, Colorado
In this case, the name does not say it all. Sure, Great Sand Dunes features 30 square miles of flowing sand — Star Dune, the highest, is 750 feet — but within its 150,000 acres, you’ll also find forested trails, alpine lakes and the 13,000-foot peaks of the Sangre de Cristo Mountains. The biggest “crowds” come in late spring to swim in Medano Creek, a short-lived snowmelt stream that flows across the sand. Come summer and fall, those with a taste for adventure (and a high-clearance 4WD vehicle) can enjoy high-country hikes and fall foliage via the primitive Medano Pass Road.
Capitol Reef National Park, Utah
With famous neighbors including Bryce, Zion and Arches national parks, it’s not surprising that some visitors to southern Utah completely miss Capitol Reef. That’s too bad because within its 400 square miles stand the white reef-like domes that give the park its name, the monoliths of Cathedral Valley and the 100-mile-long geological wrinkle known as Waterpocket Fold. The park is also home to the largest fruit orchard (2,600 trees) in the National Park system, so after a day in the outdoors, head to the Gifford Historic Farmhouse in the Fruita Historic District for fresh-baked pies of peach, pear, cherry, apple and apricot.
Lassen Volcanic National Park, California
Mt. Rainier may be more imposing, but if you want to get a sense of the explosive energy beneath your feet, Lassen’s the place. (It also gets one-third as many visitors.) From the main park road, you can view the results of the 1915 eruption in the aptly named Devastated Area, experience ongoing hydrothermal activity amid the bubbling mud pots of Bumpass Hell or make the 2,000-foot climb to the summit for the big-picture view. For a more remote experience, head to the northeast corner of the park, where the 700-foot-high Cinder Cone rises above a moonscape of lava beds and painted dunes.
Voyageurs National Park, Minnesota
Talk about a water park: With just a few short roads that barely pierce its borders, this park in northern Minnesota is a boater’s paradise of bays, islands and passages. Those without their own watercraft can rent canoes to paddle to remote islands and campsites, visit historic sites via a pair of large tour boats or recall the days of the 17th-century voyageurs by joining a 26-foot North Canoe voyage. This year, the park is celebrating its 35th anniversary with a variety of special events, including several nighttime Starwatch Cruises on Rainy Lake on board the Voyageur tour boat.
Kobuk Valley National Park, Alaska
Less than 2,000 visitors last year, but almost 500,000 caribou each spring and fall. In other words, the only crowds you’ll experience at Kobuk will likely have antlers and four legs apiece. In fact, this roadless expanse, just north of the Arctic Circle, is so remote that the U.S. Geologic Survey still hasn’t named some of its river drainages. But for those who are prepared for a true wilderness experience, rafting the Kobuk River, hiking the Great Kobuk Sand Dunes or climbing among the Baird and Waring ranges that ring the park can be the adventure of a lifetime.
Big Bend National Park, Texas
The “Big,” of course, refers to the sweeping arc the Rio Grande makes along this park’s southern border, but it also applies to the park’s approach to diversity. At 800,000 acres, Big Bend is home to more species of birds (450), butterflies (180) and cacti (60) than any unit in the National Park system. It’d take years to see it all, but for a quick trip, hike the high-country trails of the Chisos Basin, float the Rio Grande between the sheer walls of Santa Elena Canyon and bone up on local history along the new Dorgan-Sublett Trail near Castolon.
Channel Islands National Park, California
The five islands of this park — Anacapa, Santa Cruz, San Miguel, Santa Rosa and solitary Santa Barbara — are just a boat ride or scenic flight from the sprawl of Southern California, yet feel worlds away. In fact, while 350,000 people visited the park’s visitor centers on the mainland last year, only one quarter of them actually made it to the islands themselves. Add in 125,000 acres of protected waters and you’ve got a park that’s part American Galapagos (145 species are found here and nowhere else) and part playground for hikers, divers, boaters and whale watchers.
Mesa Verde National Park, Colorado
With its cliff dwellings and stone villages, this park in southwest Colorado features some of the best-preserved remnants of the Anasazi people, who lived here from A.D. 600 to A.D. 1300. Unfortunately, many visitors zip in and out, driving the Mesa Top Loop Road or visiting well-trod ruins like Balcony House and Cliff Palace. This summer, however, the park is offering three new ranger-guided tours, including a two-hour, three-mile hike to Mug House; a six-mile, six-hour tour of the Wetherill Mesa area, and an eight-hour, eight-mile hike to several remote dwellings hidden in the recesses of Navajo and Wickiup canyons
Biscayne National Park, Florida
Although Biscayne lies on the doorstep of Miami, it’s actually part of the Florida Keys, a 172,000-acre expanse of crystalline water dotted with sea-grass shallows, patches of coral and 30 keys and islets. In summer, when winds are calm and the bugs are bad, stay on the water with a guided snorkel trip to the natural aquaria around Shark Reef or Bache Shoal; when fall winds pick up (dispelling the mosquitoes), take a three-hour tour to Boca Chita Key where you can climb the 65-foot ornamental lighthouse for panoramic views of the park, Key Biscayne and downtown Miami.
Gates of the Arctic National Park and Preserve, Alaska
No roads, no visitor facilities and no designated trails — if it’s solitude you seek, this 13,000-square-mile park above the Arctic Circle has your number. (Total number of visitors last year: 9,975.) Some visitors arrive by bush plane; others hike in via Anaktuvuk Pass, but all would be advised to plan ahead, either by using a guide service or being appropriately self-sufficient and wilderness-savvy. The rewards? Endless days under the midnight sun in summer, caribou migrations in spring and fall and panoramas of wild rivers, glacier-carved valleys and the craggy peaks of the Brooks Range year-round.
Great Basin, Nevada
Given Great Basin’s location — just off U.S. 50, aka The Loneliest Road in America — it’s hardly surprising that the park accounted for a measly .03 percent of visits (85,000) to the National Park System. Most visitors come to tour the limestone wonderland of Lehman Caves or hike amid the gnarled, 4,000-year-old bristlecone pines on Wheeler Peak. It’s also popular (relatively speaking) with stargazers who come to the park because it boasts some of the darkest night skies in the Lower 48. Consider joining them August 6–8, when the park will hold its first-ever Great Basin National Park Astronomy Festival.
Dry Tortugas National Park, Florida
Seventy miles west of Key West and surrounded by the turquoise waters of the Gulf of Mexico, Dry Tortugas saw just 52,000 visitors last year — probably because you have to take a ferry, seaplane or private boat to get there. Once on site, visitors can tour the hulking Civil War–era Fort Jefferson, stroll the beach of Garden Key (most of the other islands are closed to the public) and snorkel amid conchs, corals and kaleidoscopic fish. (Park personnel are monitoring the local waters for oil from the Deepwater Horizon spill, but are currently reporting no evidence of contamination.)
Wrangell-St. Elias National Park and Preserve, Alaska
The largest park in the National Park system spans 13.2 million acres, features nine of the 16 highest peaks in the country and boasts the continent’s greatest assemblage of glaciers, yet received less than 60,000 people last year. Crowds? Not a problem. Most visitors drive the 60-mile McCarthy Road to visit the rustic town of the same name, tour the Kennecott Mill site or hike up to the toe of Root Glacier. If that sounds too busy, opt instead for the lesser-traveled Nabesna Road, which offers equally stunning scenery and more chances to see wildlife.
Black Canyon of the Gunnison National Park, Colorado
Rocky Mountain National Park got 2.8 million visitors last year. Black Canyon of the Gunnison? Less than 175,000. Cut steep and deep by the thundering Gunny, the canyon’s near-vertical walls rise as high as 2,700 feet above the water and provide a vivid (and vertiginous) view of 2 billion years of geology. Most visitors stick to the more-developed, easier-accessed South Rim, so consider the more primitive North Rim for equally impressive views with even fewer people. “There’s only a quarter of a mile between them,” says Chief of Interpretation Sandy Snell-Dobert, “but it’s so much quieter.”
Theodore Roosevelt National Park, North Dakota
Let’s face it, without Teddy Roosevelt, the U.S. would probably have far less protected space than it does, so a visit to his one-time homestead is more than appropriate. (Besides, it gets half as many visitors as the better-known Badlands.) Most visitors hit the South Unit, snapping pictures of T. Roo’s cabin and the Painted Canyon, while others venture to the North Unit to see prairie dogs and river views. Only a handful make it to the remote Elkhorn Ranch Unit, which Chief of Interpretation Eileen Andes says features “the best view of the Little Missouri and maybe the best view in North Dakota.”
Isle Royale National Park, Michigan
Closer to Ontario than Michigan, this island park in Lake Superior is only accessible by boat or seaplane, which probably explains why it saw only 15,000 visitors last year. For day trippers, easy trails around Windigo and the lodging and tour services at Rock Harbor offer scenic views and glimpses of island history; for canoers, kayakers and backpackers, the bays, interior lakes and backcountry trails are as wild as they come. Ferries and water taxis can transport you to remote docks scattered along the 45-mile-long island; after that, you’re on your own.
Guadalupe Mountains National Park, Texas
Heading to Carlsbad Caverns? If so, consider adding a visit to Guadalupe Mountains National Park, which sits just an hour away, sees less than half as many visitors and offers some of the Southwest’s most surprising topography. Check out the unexpectedly lush vegetation in McKittrick Canyon, the 265-million-year-old marine fossils along the Permian Reef Trail and the backcountry trails off the park’s remote Dog Canyon entrance. Prefer some company? This summer, the park is offering its first Hike with a Ranger program, which will offer full-day backcountry hikes with a ranger on the last Sunday of the month.
National Park of American Samoa, American Samoa
They don’t come much more remote — or more scenic — than this little beauty, which is located 2,600 miles southwest of Hawaii, spread across four islands and blessed with tropical rainforests, pristine beaches and gin-clear waters teeming with fish. Start your visit with a scenic drive to Vatia on the main island of Tutuila, then hop a flight to Ofu or Olosega for beachcombing and snorkeling. More intrepid visitors should also visit Ta’u, the fourth island, which is considered the birthplace of the Polynesian people. “Access is difficult,” says Park Ranger Sarah Bone, “but the reward will pay for itself several times over.”
