Black sand beaches in general are pretty neat but add in the environment of Hawaii and Waipio Valley and you have a magical place. This beach is open to the public but to reach this location a four wheel drive vehicle is required. There is actually someone that checks to make sure. The drive down is dangerously steep and rugged but once at the bottom there are many scatter trails that lead to the black sand beaches. If I had to pick my favorite location on the big island this would be it.
