Fox News Digital asked travelers in Las Vegas this week about the most surprising costs and fees they've seen during their trip as tourism numbers keep dropping for Sin City.

National Geographic has released its annual Best of the World travel list, featuring must-visit destinations around the world.

The 2026 round-up called out four locations in the United States -- including scenery and sites in North Dakota, Oklahoma, Hawaii and Pennsylvania.

Below are the U.S. states that NatGeo recommends visiting in the next year.

North Dakota's Badlands is known for its rugged landscape, including sweeping hills, prairie grasses, canyons and rock formations, as well as native wildlife.

The area is also home to Theodore Roosevelt National Park and will welcome the Theodore Roosevelt National Library on July 4, 2026.

According to NatGeo, Roosevelt "sought refuge" in the Badlands and hunted bison in 1883, which later shaped the president's character and thoughts on conservation as wildlife disappeared.

Next summer, the new library, measuring 93,000 square feet, will be "perched high on a butte" in the town of Medora, the publication shared.

The library will reportedly include interactive exhibits on Roosevelt's history and travels. The structure will also include a walkable roof covered in native vegetation that will be a part of a 1.3-mile trail toward the national park.

America's famous Route 66, spanning the country from Chicago, Illinois, to Santa Monica, California, will celebrate its 100th anniversary in 2026.

TOURISTS FLOCK TO SEE ICONIC LANDMARK FINALLY FREE OF SCAFFOLDING AFTER 200 YEARS

NatGeo recommends taking the "Mother Road" through Oklahoma, which has been getting an "Americana glow-up."

In the last four years, the Oklahoma Department of Transportation has invested more than $82 million on the state's 400-mile stretch of iconic roadway, including "re-lit neon signs, revived motor courts and roadside attractions," according to the article.

Taking the road through the Meadow Gold District along 11th Street will lead to indie retail locations, "campy outdoor statues," art galleries, "quirky" gift shops, record stores and western vintage boutiques.
