Among America’s 61 national parks, some stand out as must-sees for most RV travelers: Great Smoky Mountains, Yosemite, Zion, and the Grand Canyon all come to mind as bucket-list sites. And indeed, these and other parks welcome millions of visitors each year. Yet there are many other lesser-known parks equally worth your time—parks with extraordinary wildlife and unique natural features that mere thousands of visitors experience annually.
We’ve rounded up the least-visited national parks and make a case for why each is worth a visit. Some are little-known, others are obscurely located, but all celebrate the beauty of America’s natural wonders—and, as a bonus, can be enjoyed with fewer crowds.

Most visitors come to see the ancient tree trunks, which are preserved by minerals they absorbed after being submerged in a riverbed nearly 200 million years ago. And they’re quite a sight: Over time, the huge logs turned to solid, sparkling quartz in a rainbow of colors—the yellow of citrine, the purple of amethyst, the red-brown of jasper. This mineral-tinted landscape also boasts painted deserts and striated canyons.

Mesa Verde is the largest archeological preserve in the U.S., with over 500 distinct sites and 600 cliff dwellings. Those dwellings were once the homes that native peoples used for several centuries. Today, visitors can explore the dwellings, learn about the native culture, and marvel at both the safeties and dangers offered by living several hundred feet off the ground, in structures tucked into small openings on the cliff face.

The only cave system on our list of least-visited parks is located in New Mexico beneath the Chihuahuan Desert. Carlsbad is not just one cave; more than 100 caves form the park, Carlsbad Cavern itself forming the natural entrance to the park as the tallest cave. The Big Room, a large limestone chamber, is nearly 4,000 feet long, 625 feet wide, and 255 feet high.

Located in the northern part of California, Lassen Volcanic is best known for the astounding hydrothermal sites within its bounds. Many established trails take you past—and through—those bubbling springs, including Bumpass Hell, an area with acres of bubbling mud pots. As the name implies, Lassen Peak is a volcano. On the side of the mountain, visitors can observe lava rocks left by its last eruption in 1917.

Deep in the heart of Southwest Texas lies the well-known, but rarely visited, Big Bend National Park. In spite of its remote location, Big Bend is worth the drive. The entire Chisos Mountain Range, a portion of the Chihuahuan Desert, and the Rio Grande form spectacular scenery here. Visitors enjoy hiking and backpacking and it’s a certified dark-sky park, offering an unparalleled view of the night sky.

The unique landscape of towering rock formations that form “pinnacles” is the result of volcanic activity in the area some 23 million years ago. Pinnacles offers hiking and climbing, with spectacular views; come during spring to see blankets of colorful wildflowers, and stay after sunset to take in the star-studded sky.

Congaree offers the opportunity to explore the largest intact expanse of old growth bottomland hardwood forest in the southeastern U.S. The park includes the area where Congaree and Wateree Rivers converge. Canoeing, hiking, and fishing are all popular pastimes and may be enjoyed in peace thanks to the sparse number of fellow travelers.
We can never have enough of nature.
