We all want to venture into the unknown, follow unbeaten tracks and travel through the most remote and unspoiled nooks of the world. Still, there are some vistas in the world that must be seen at least once in a lifetime, and USA can boast an ample share of such.

Iconic, world-renowned and, above all, amazingly beautiful, the Golden Gate Bridge in San Francisco is another American spot worth travelling as far as to the southern edge of the country. The architectural marvel spanning the Golden Gate strait has become an internationally recognizable image of the city and, in fact, the entire nation.

The state of Hawaii is truly unique and Na Pali Coast is its precious jewel. Located along the northwest side of Kauai, the oldest inhabited Hawaiian island, the jaw-dropping coast is placed high on the must-be-seen list of the USA's wonders. The coast is best enjoyed when reached by hiking or boating. Picture-perfect Na Pali looks especially amazing when watched from a helicopter.

5. New York Skyline

By Stuck in Customs

No wonder New York City skyline is the most easily recognizable skyline in the world. No other city on the globe can boast such a spectacular silhouette comprised of 48 buildings exceeding 200 m. The view is certainly most fascinating at night. But mind you...it can easily become addictive.

Witnessing the Fire Falls in Yosemite Park is one of a kind experience because this natural phenomenon occurs only in February every year. So if you happen to be in the park in February, try to find the Horsetail Waterfalls set in the Yosemite Valley. The visual perception of a fire falls is created by the sun that illuminates the fall from behind. Don't worry if you don't manage to see this spectacular optical illusion though - the park itself is an absolutely marvelous place to visit anyways.
