The Illinois stretch of Route 66 is home to several great roadside attractions, but nothing shouts "retro kitsch" louder than a massive Muffler Man. Snap a picture with the Gemini Giant the newly-reopened Launching Pad Drive-In in Wilmington. Named for the Gemini space program, he’s one of many similar statues made by International Fiberglass.

If you need a break from driving, pull over at the Fantastic Caverns in Springfield and explore an underground world. North America's only completely ride-through cave tour is absolutely worth the 55-minute tram ride.

The Blue Whale of Catoosa was built by Hugh Davis in the early 1970s as a surprise anniversary gift for his wife Zelta, who loved whales and collected whale figurines. Take time to wander around the remnants of this famed roadside wonder, and have a snack at one of the picnic tables.

Everything is bigger in Texas, so you may as well try your luck with the 72-ounce steak challenge at the Big Texan Steak Ranch in Amarillo. The current record-holder is Molly Schuyler, who devoured three steaks (plus sides) in just 20 minutes in 2015. The restaurant also features a shooting gallery, arcade games, a huge gift shop, and a bull statue out front.

The iconic Blue Swallow Motel in Tucumcari has been open since 1939. As far as vintage neon signage goes, it doesn't get much better than the Blue Swallow's classic sign. If you can, stick around until dusk, it’s worth the wait. And there’s a reason for the classic “Tucumcari Tonite!” campaign—there’s no better place to stop for the night. Many rooms at the Blue Swallow come with their own garage, so you can stow your car, grab a lawn chair, and sit outside to bask in the glow of neon.

The historic El Rancho Hotel in Gallup was built by Joe Massaglia in 1936 and has been featured in dozens of old Hollywood movies. The Western-style hotel is listed on the National Register of Historic Places and features wagon-wheel headboards and suites named after famous Hollywood Western stars. Even if you don't spend the night here, at least pull over to check out the epic hunting lodge-inspired lobby, which is full of antiques and Native American decor.

A forest in the middle of Arizona’s grassland may sound odd, but Petrified Forest National Park is unlike any other forest in the country. The park is packed with gems—quite literally, since the ancient wood has been turned into sparkly stone—that anyone, from the outdoor enthusiast to the science geek, can enjoy.

Drive through the Painted Desert and Petrified Forest National Park in the late afternoon and then stop at Wigwam Village Motel #6 for the night. The rooms of this charming historic motel—located inside individual concrete and steel teepees—are pure roadside kitsch. There are only three remaining Wigwam Motels, and the vintage cars parked outside of each room make this the best one for photos.

When Juan and Mary Delgadillo opened the Snow Cap Drive-In on Route 66 in Seligman in 1953, they probably didn’t anticipate it becoming a worldwide tourist attraction. More than 60 years later, Delgadillo's Snow Cap Drive-In is one of the most sought-out Route 66 destinations.

Roy's is located along a desolate stretch of the Mother Road in the tiny desert town of Amboy. The motel, cafe, and gas station has appeared in numerous movies and is one of the best photo ops along the entire route. The iconic neon sign has recently been restored so it looks great day or night.
