Watching 1. Secret Yellowstone
National Geographic goes beyond the tourist hotspots and travels deep inside the 2 million acre national park to reveal the backcountry wilderness few have seen. Explore some of the 300 newly discovered waterfalls and learn how wolves, back after five decades of absence from Yellowstone, are helping restore the balance in the ecosystem alongside the grizzly bear and bison. Finally, discover how the geology of Yellowstone with its giant well of molten lava underneath the surface is sometimes more dangerous than the wildlife.
2. Secret Yosemite
Known for its steep granite cliffs, impressive waterfalls and the world's largest living trees—the Giant Sequoias—Yosemite attracts vacationers all year round. With more than 700,000 acres of land, this terrain is home to a host of wild creatures ranging from black bears, bobcats, foxes, snakes and a variety of bats. Discover this vast wilderness as National Geographic explores the life within the wilderness found beyond the postcard-perfect views.
3. Extreme Alaska: Denali National Park
Located near the top of the world, Denali National Park is home to more than six million acres of extreme wilderness. Venture beyond the tourist hotspots and join National Geographic on a low-to-high-altitude trek through Denali's breathtaking ecosystems. Elevation sets the rules in this subarctic land where only the most hardy creatures can survive.
4. Everglades
The Everglades is many things to many people, but above all else, it is a wilderness-1.5 million acres of the most extraordinary and unique habitat. 1,100 species of plants and 350 species of birds live here for at least part of the year, and some of those species live nowhere else on earth. We'll journey into the Everglades on foot, by airboat, on a helicopter and by kayak to see what secrets this wild space is hiding.
5. Grand Canyon
National Geographic joins a rare scientific expedition to explore the Grand Canyon's entire 277-mile length. Explore the canyon's geological history, study the microscopic colonies of vegetation that survive where no other plant can and examine its many unique creatures to unlock some of the mysteries of this wonder of the world.
6. Death Valley
Journey with National Geographic, from Death Valley's highest peak at 11,049 feet, to its lowest point, a staggering 282 feet below sea-level, and meet the scientists who are working to protect this wild place as the mercury rises.
7. Hidden Hawaii
America's newest marine sanctuary, Papahanaumokuakea Marine National Monument, encompasses the Northwestern Hawaiian Islands. The monument is bigger than all U.S. national parks combined--yet the majority of this environment has never been seen. What is in this vast marine conservation area? And, what will it take to protect it?
8. Canyonlands
Canyonlands is the little-known jewel of the American National Parks. This stark landscape of extraordinary features contains more than 300,000 acres of desert wilderness, towering spires and spectacular canyons. But this rugged terrain is more than a pretty picture--it is a history book of time. Its stories stretch from the geologic forces that created this land, to the beginnings of life on earth and from ancient people, to the cowboys and outlaws of the Old West. Venture beyond the tourist hotspots and discover the hidden secrets of Canyonlands National Park.
9. Glacier National Park
Glacier National Park in Montana is arguably America’s most stunning landscape, with carved massive glaciers and a melting ice cycle that supports ecosystems of more than 2,000 species of plants and animals. However, the glaciers are disappearing at a rapid rate and may be gone in just 10 years. Following the collapsing of the park's most prominent mountain of ice, National Geographic treks into the Continental Divide to uncover the hidden secrets of this transforming landscape.
10. Appalachian Trail
For more than half of the U.S. population, the Appalachian Trail is less than a day's drive away. Yet despite its proximity to many major cities, few truly know the splendor of this national treasure. National Geographic travels off the beaten track to discover the remote and often unknown corners of the 5-million-step journey.
11. Pacific Crest Trail
The Pacific Crest Trail zigzags some 2,650 miles from Mexico to Canada. It cuts through seven national Parks and 24 national forests as it travels through California, Oregon, and Washington. It's a trail of ever-changing obstacles--from some of the highest mountain passes in the west to some of the hottest desert in the country. The two to three hundred hikers who attempt the PCT each year often find out quickly if they have what it takes for the journey ahead.
