Ever worry that you will run out of places to explore in America? Lucky for you, there are 63 national parks and 424 national park sites across the country—it will take a long time to work your way through the 85 millions acres they encompass. And with additional sites being earmarked for conservation (West Virginia’s New River Gorge was just designated as a national park in 2021, for example), the list of destinations keeps growing and growing.

Remember, it takes some planning to visit the national parks, though the journey you make of it will be worthwhile. One way to optimize the experience is by targeting the lesser-known parks. Avoid the snaking lines at the Grand Canyon and take in the wrinkly sandstone at Capitol Reef. Skip the tortuous campsite-booking system at Acadia and sleep on the sands of Indiana Dunes. Smaller parks might mean fewer amenities and tour outfitters, but that’s where the real beauty of wilderness shines through. Let us know in the comments what your favorites and underrated choices are.

Guadalupe Mountains National Park, Texas

Guadalupe Peak in Guadalupe Mountains National Park is in Texas
Guadalupe Mountains is home to the four highest points in Texas and the bright-white Salt Basin. During the Pleistocene Epoch, this Salt Basin was covered by a shallow lake but today it’s dry most of the year. This photo captures one of the rare times when there’s water—this usually happens in the summer. While the Basin is covered in gypsum and salt, the nearby dunes consist of pale red quartz grains.

Indiana Dunes National Park, Indiana

Indiana Dunes National Park in Indiana is a refuge of sand dunes, wetlands, and woodlands. Canoes are welcome on the shores too.
While the Indiana Dunes maintain a legacy of modern scientific inquiry that began towards the end of the 19th century, this landscape had already been studied by Native Americans for thousands of years. Their vast knowledge of the region reveals an intimate past of research. Indiana Dunes National Park is one of nine parks that are within the federal government’s Great Lakes Inventory and Monitoring Network. National parks within the boundaries of Lake Michigan and Lake Superior are monitored and studied for wildlife and plant populations, changes in the landscape, and effects of pollution on the environment. Great Lakes Network scientists use the parks for science and use the science to make management decisions to help the parks. National Park Service

Petrified Forest National Park, Arizona

A slice of the Crystal Forest Trail in the Petrified Forest National Park. It was originally called First Forest as it was the first large accumulation of petrified wood reached from Adamana, Arizona. The petrified log segments continue to erode from the 216-million-year-old bed, which caps the exposures in the area, including Blue Mesa, Agate Bridge, and Crystal Forest. The historic access point built in the 1930s was closed in 1965 to reduce illegal petrified wood removal. Hallie Larsen/National Park Service
