Drive down one of America's many highways, and you're bound to pass something interesting sooner or later. The country is famous for its quirky roadside attractions, which can take the form of anything from unique museums to giant balls of twine. To see which destinations are worth a stop on your next cross-country road trip, check out the list below.

Money.co.uk analyzed Instagram hashtags and TripAdvisor reviews to determine the 10 most popular roadside attractions in the United States. Salvation Mountain in Southern California earned the top spot from the website, and anyone who's been there can see why. The 50-foot-tall, 150-foot-wide mound in the Sonoran Desert is a folk art icon. More than 100,000 gallons of paint were used to decorate the mountain with depictions of nature and bible verses, and today it's a well-trafficked photo op.

No. 2 on the list is Seven Magic Mountains in the Nevada desert. This American Stonehenge consists of seven 30-foot-tall pillars made from neon-colored sandstones. The art installation is temporary, so tourists wishing to see it should plan their visits for before the end of 2021.

Not every attraction on the list was built by people. Wyoming's Devils Tower, which occupies the third spot, is the most popular natural rock formation to visit on American road trips, according to reviews and hashtags. But most of the landmarks are pure kitsch, like the world's largest beagle statue in Idaho and the SPAM Museum in Minnesota.

No matter where you're traveling in the country, there's likely a detour-worthy destination close by. After reading the full list of the 10 most popular roadside attractions in the U.S., check out these interesting stops in all 50 states and Washington, D.C.
