Areas designated specifically as national parks account for 63 of those locations. While well-known spots like Grand Canyon and Yosemite National Parks bring in more than 4 million visitors a year each, some of the lesser-known ones have minimal visitors, plenty to do, and much-needed peace and quiet. Be sure to add these least-visited national parks to your 2014 list of camping destinations.
Gates of the Arctic National Park and Preserve, AlaskaVisitors: 11,012 1 of 11
Alaska has long been a dream destination for many outdoor lovers, campers and hikers, and for good reason: this state is home to four of the largest national parks in the country, including Wrangell-St. Elias, which takes the number one spot.
Instead of visiting the most popular parks, take the road less followed--literally; there are no roads or trails in the Gates of Arctic National Park, but that shouldn't stop you from visiting.
At Gates of the Arctic, the number one least-visited national park, you're immersed in a pristine wilderness straight out of a storybook. But, it's not for the faint of heart. "Gates of the Arctic is one of the last truly wild places on earth," according to NPS.gov.
All camping here is backcountry, and you need to be taken in and out of the park by pre-arranged transportation, most often a plane. If you're up for an adventure, now's the chance to test your skills.
Lake Clark National Park and Preserve, AlaskaVisitors: 13,000 2 of 11
Another Alaskan gem, this park provides hundreds of miles of recreation and beauty that no camera could possibly capture. While there's no developed camping in this national park, there is a designated camping area in Port Alsworth, and you don't need a permit to pitch your tent and make basecamp there.
When you're not resting under the stars, you can fish or boat in all 51 miles of serene Lake Clark. Rent a canoe in Port Alsworth if you don't have one. If you want to stay on land, take a hike to Tanalian Falls, trek up Tanalian Mountain or stroll around Konstrashibuna Lake.
Isle Royale National Park, MichiganVisitors: 16,274 3 of 11
Escape from the world when you step into this national park, where you'll find scenic hiking, calm waters, and soul-shaking solitude. In fact, the only way to get there is by ferry and you need to make a camping reservation or you won't be able to stay for the night.
Once you arrive, and shake off the awe, start trekking. With a Michigan fishing license, you can catch breakfast, lunch and dinner, or just sit by the water for a relaxing afternoon in the sun. Don't forget to sign up for a guided, in-depth hike; take a trip to Daisy Farm Area, a historic settlement; or hop on a guided cruise tour.

Kobuk Valley National Park, AlaskaVisitors: 16,875 4 of 11
Great Sand Dunes National Park isn't the only place with dunes worth seeing. The Great Kobuk Sand Dunes, located in this park, rise more than 100 miles high and come in many different shapes and sizes. Unfortunately, the weather at this park is not always favorable, as rain, wind and snow are common occurrences, even in the summer months.
To stay here, you need to be a skilled backwoods camper. Similar to Gates of the Arctic, there are no roads or trails here, just miles and miles of untouched wilderness. If you're up for a backpacking adventure, head to the scenic Baird Mountains or float along the Kobuk River, stopping only the explore the land and sleep.

Dry Tortugas National Park, FloridaVisitors: 58,401 6 of 11
History buffs, this park is for you. Dry Tortugas is home to 19th century Fort Jefferson, the largest all-masonry fort in the country. Built as the gateway to the Gulf of Mexico, this fort has seen history that most can only read about in textbooks. As you tour around the fort, notice its unique brickwork and 2,000 arches.
This park is accessible only by boat or plane, and its clear, turquoise waters are a big draw for water lovers. Check out the ocean underworld with a snorkeling trip, grab your binoculars and enjoy "world class bird watching," or just sit back with your toes in the sand. End your night at Garden Key, the only campground on the island. Note that this is a 10-site, first-come, first-served, primitive campground, so it's important to plan ahead.
Great Basin National Park, NevadaVisitors: 92,893 7 of 11

Black Canyon of the Gunnison National Park, ColoradoVisitors: 175,852 10 of 11
Black Canyon is "big enough to be overwhelming, still intimate enough to feel the pulse of time," according to the National Park Service. You'll feel small as you stand next to 2,000-foot tall canyon walls, but don't let that stop you from lacing up your boots and seeing just what this park is made of.
For your best view of the park, take a hike along the rim. On the south rim you'll find four trails, which range from a 1-mile loop to a 2-mile round trip. If you want a longer hike, try the 5-mile Deadhorse Trail on the north rim. Or just find a spot next to the Gunnison River and sit back with a fishing pole in hand. At the end of the day you can relax at one of two developed campgrounds.
