The Grand Canyon is one of the most visited natural wonders in America, but Arizona also offers a number of other sights worth seeing along the way. Traveling to the Grand Canyon in an RV affords you the chance to stop off and visit unique roadside attractions along the way to make the journey even more memorable. You could swing by "The Thing," a mysterious museum and souvenir shop in Dragoon, just off Interstate 10, for example.

Tour Biosphere 2 in Oracle

If you've ever seen the cult classic Bio-Dome, you will love Arizona State's Biosphere 2, a massive facility dedicated to studying Earth just north of Tucson. The 3.14 acre facility is completely sealed off, and scientists have been sealed inside for extended periods of time, just like in the Pauly Shore flick. Now, visitors are able to enter and tour the visitor center buildings to learn more about the project.

Cross London Bridge in Lake Havasu City

When you were a kid, there's no doubt you sang or at least heard the song, "London Bridge is Falling Down," but did you know that very same bridge is actually still standing? It's just not in London anymore. Time Magazine states the structure, which holds the Guinness World Record for the largest antique, was moved to Arizona in 1971. You might not be able to drive your RV across the nearly 200-year-old bridge, but you and your family can get out, stretch your legs and walk to the other side and back.

Grab a bite at the oddly designed Longhorn Bar and Grill in Amado

There's no rule stating you have to cook every meal at RV campgrounds on your road trip. It's fun to indulge and visit a restaurant or two on your vacation, especially if you want to dine at a place like the Longhorn Bar and Grill in Amado. Open since the 1970s, this restaurant is hard to miss, as the entrance is a giant longhorn skull and the building itself is shaped to look more like a rock than an eatery. RoadsideAmerica.com states the restaurant, despite its name and design, is not a steakhouse but serves Italian food. If you're craving a Texas steak, you'll find the Cow Palace Restaurant across the street. This establishment was a hot spot for celebrities in the 1930s.
