The road trip is an undisputed staple in the American vacation experience. Whether it’s a couple of hours or a couple of days, the journey is often just as much of an experience as the intended destination.

U.S. News rounded up some of America’s most unusual roadside attractions, from the downright cool to the borderline weird. Read on to see which of these oddities is worth the detour.

Situated in the remote desert of Southern California lies one of America’s most unique roadside attractions, Salvation Mountain. This labor of love comes from Leonard Knight, a local who wanted to create something that showcased his devotion to his faith that not only he, but everybody, could enjoy. The mountain, located off Highway 111 about 80 miles southeast of Palm Springs, is made of adobe clay and covered in thousands of gallons of colorful paint, featuring murals, messages and imagery depicting Bible verses. Should you choose to visit, avoid summertime, which sees daytime highs of 105 to 120 degrees. Salvation Mountain is open from dawn till dusk.

If you’re traveling to Arches or Canyonlands national parks, chances are you’ll run into Hole N” The Rock. Located just off of Highway 191 in Moab, Hole N” The Rock was once a 5,000-square-foot, 14-room family home that required 50,000 cubic feet of sandstone excavation. The home’s owners, Albert and Gladys Christensen, lived here until Albert’s death in 1957. Today, the home is vacant, but available for tours. You’ll also find a small zoo, a general store and plenty of southwestern souvenirs on-site. Tours of Hole N” The Rock cost $6 for adults and $3.50 for children ages 5 to 10, and the attraction is open from 9 a.m. to 5 p.m daily.

What’s more fitting for a roadside attraction than an homage to automobiles? That’s what you’ll find at Carhenge, a replica of Stonehenge. The cars featured are all vintage American automobiles, painted gray to imitate the historic English landmark. You’ll find this clever adaptation of the famous UNESCO World Heritage site in Alliance, Nebraska, just off of Highway 87. There is also a gift shop on-site, but note it is only open during the summer months. Carhenge is free to visit and it is open 24/7 year-round
