RealTravel (http://realtravel.com), a travel blogging and travel guide site that helps more than half a million people plan trips with advice from other travelers every month, today announces top 10 hidden -- and some not so hidden -- American treasures, according to RealTravel editors and newlywed bloggers Team Edwards.

1. Avenue of the Giants (Northwestern California)

It was by far one of the oddest sights we’ve experienced

Recommended in any California travel guide, the Avenue of the Giants is located just off highway 101 near Humboldt Redwoods State Park. This stretch of asphalt weaves back and forth under the 101 through the Redwood Forest where many of the tallest trees in the world reside. Upwards of 360 feet, these colossal trunks seem to disappear into the clouds as you gaze skyward in awe. Continuing along this route, you will reach the town of Meyers Flat, home of the famous Drive-Through Tree. Here, you can pay a small admission fee to enter the private property on which it stands, and then proceed to literally drive your car through a natural opening in the trunk of one of these mighty trees. A peaceful yet humbling drive, this route shouldn’t be missed.

2. World’s Largest Fountain (Fountain Hills, Arizona)

A suburb of Phoenix, Arizona, Fountain Hills hosts the world’s largest fountain. It’s located in the middle of a large pond and shoots a large stream of water over 600 feet (that’s two football fields!) into the air. “It was by far one of the oddest sights we’ve experienced," writes Team Edwards. “Apparently the fountain is on a schedule — on for 10 minutes, off for 10 minutes. Luckily, we happened on it while it was on. The pond and fountain were part of a beautiful park, complete with ducks and cactus gardens.”

3. Custer State Park (Custer, South Dakota)

Nestled in the Black Hills is Custer State Park, 71,000 acres of beautiful land and wildlife. Needles Highway, a narrow winding road that swerves through giant needle-like rock formations jutting 30 and sometimes 40 feet in the air, runs through the park. Full of wonderful photo opportunities, this scenic drive offers an amazing view of Mount Rushmore framed like a picture through the one-lane tunnels that lead you through the park, and the park also hosts another famous mountainside monument, the Crazy Horse memorial.

4. Ruby Falls (Chattanooga, Tennessee)

Just across the Georgia border lies Chattanooga, Tennessee, home of Lookout Mountain and the famous Ruby Falls, a natural waterfall located 1,500 feet underground. An elevator takes tour groups up nearly the height of the Empire State Building into the side of the mountain, where a guide leads you through the beautiful cavern. Along the way, tourists will pass several interesting geographical formations before arriving at the falls. Once there, climactic music pours from unseen speakers while giant spotlights illuminate the falls in an impressive reveal.

5. Badlands National Park (Southwestern South Dakota)

Team Edwards describes the terrain of the Badlands: “This destination has to be the strangest thing we’ve seen in all our travels. The geography here in this 20-mile stretch of road is equivalent to that of another planet. We pulled off the road and hiked down a trail out into the actual formations, walking around and climbing on the dunes. The ground is like a mixture of dried mud, sand and dust. Every time it rains or the wind blows, the landscape changes. It’s uninhabitable (except for the wild rabbit we saw), but breathtaking. There really aren’t words to describe this geographical oddity. It’s something you just have to experience for yourself.”

6. The Enchanted Highway (Regent, North Dakota)

If you’re looking for a fun thing to do in North Dakota, you must visit the town of Regent and the Enchanted Highway. Recently featured in Smithsonian magazine, the Enchanted Highway is a strip of small farm road with seven large scrap-metal sculptures, created by a local teacher-turned-artist Gary Greff in an effort to boost the town's economy. Each work of art reflects a North Dakota theme and is displayed on farmland that has either been donated or leased, and a semi-paved road leads up to each one, complete with picnic table and description of the piece.

7. James Pecan Farm (Brunswick, Missouri)

Brunswick, Missouri is home of the world's largest pecan. A unique “pop-up theater” is located here as well, the creation of a local man, Farmer James, which consists of a larger-than-life pop-up book of live theater. “This is a must see for anyone traveling through this area -- kids and adults alike will enjoy it,” says Team Edwards. “Farmer James also has plans for a mini-amusement park to help boost the Brunswick economy.” His farm and store can be found along Route 24, just west of Brunswick in northern Missouri.

8. Storybook Land (Aberdeen, South Dakota)

Hidden in the northern part of South Dakota, this free amusement park is based on nursery rhymes, children's stories and some movies. Team Edwards were enchanted by this fairytale park: “There were several things for kids to play on (slides, a giant pirate ship, monkey bars), and there were even a couple of petting zoos. If you crossed over into the other half of the park, you found yourself in the Land of Oz. Munchkinland, the yellow brick road and even the haunted forest guided the way to the Emerald City, where there were a few small rides, which you could ride for a dollar. We took the train ride around the park, where we not only got a great view of the park, but also got to see the small zoo nearby (complete with buffalo and reindeer)…the park, completely supported by donations and free to the public (with the exception of the rides and food), is a MUST for anyone traveling through South Dakota.”

9. Corn Palace (Mitchell, South Dakota)

Just south of Aberdeen lies the town of Mitchell, home to the Corn Palace. Acting as the town's functioning civic center, this building hosts important local events. The most unique thing about this building is the fact that every year, the town's residents decorate the outside of the building with different varieties of corn. The mural on the outside of the building changes every year (crop permitting) while another mural indoors depicts various aspects of the state's history. Tours are available, and a large gift shop occupies the indoor arena. The surrounding neighborhood is entertaining as well, with fun shops and great photo opportunities.

10. Whistle Stop Café (Juliette, Georgia)

Made famous in the 1991 film "Fried Green Tomatoes," the Whistle Stop Café is the pride of this charming town. Juliette itself is a quaint, back-roads place; with a great view of small-town Georgia and the sound of the train passing by, you really get the feel of the old South.
