Hawaii is one of the most popular vacation destinations in the world. As such, some travelers think Hawaii is too touristy and over-crowded. While both of these observations are in many ways true, there are less touristy things to do in Hawaii. I grew up on Oahu and have experienced this island as both a child growing up and an adult returning home as a tourist. In truth, Oahu has changed and developed so much over the past several years that I barely know where to visit anymore.
