If you're looking for a place to get away, Hawaii is the best choice.  When you're not exploring, there are plenty opportunities to relax and enjoy yourself.  Pearl Harbor is one of the most Historical places in America, and it's located in Hawaii.  It's a lagoon harbor and is the headquarters of the United States Pacific Fleet.  It was also bombed by Japan long ago.  One thing you'll find in Hawaii that you can't find anywhere else in America, is Volcanoes.  Hawai'i Volcanoes National Park is a place where you can walk around and observe small, safe, and managed volcanoes.  It would be an amazing experience.  Sea life park is also another place you should consider stopping by on your trip.  It lets you observe and interact with native animals in their natural habit while in a cultural environment as well.  The Ha'iku stairs, also known as the "Stairway to Heaven" is a steep hiking trial located on the island of O'ahu.  It's believed to be haunted and is very dangerous, yet a popular tourist attraction.  I hope you enjoy your stay, Aloha!
