Another thread triggered a thought in me about what are some activities and sights, unique to Hawaii or Oahu or even Waikiki? It seems sometimes visitors think Oahu is just like the Caribbean or Mexico with zip lines and parasailing, ATVs and water trampolines, etc as the common experiences that tourists partake in.
So what is unique in Hawaii, especially Oahu?
I can't think of anyplace else in the world that offers outrigger canoe surfing the way Waikiki does.
Hawaii is where Stand Up Paddling was "invented" and was the home of the modern rebirth.
The catamaran is a Polynesian innovation that brought the ancients from the South Seas to HI and few places have as many catamaran trips as Oahu does, not even in other spots in HI or the South Pacific.
Not a lot of people in the U.S. knew much about Hawaii and even fewer had ever heard of Pearl Harbor before Dec. 7, 1941, but by the end of the day everyone in the U.S. knew where it was and now the USS Arizona is the most popular site on Oahu, maybe all of HI.
The Polynesian Cultural Center is also unique to Oahu.
So what else is unique to Oahu and Waikiki?
