There’s a lot of current and swell at South Point, the southernmost tip of both the Big Island and the United States. Not far from the spot where people jump off the cliff into the ocean (not all of them make it back alive!), there’s a hole in the cliff where water surges in and out. This spot also has an opening above and is a great place to watch this wave action. I particularly like the pink rocks and the frothy white water as the waves recede.
