Peepee Falls on the Wailuku River in Hawaii sends a steady stream of water that tinkles on the rocks below and sometimes splashes back a bit. You can call it Pe’epe’e as the locals do although this doesn’t sound like the real thing to us. However you won’t get much privacy when you need it because everyone there has come to Peepee for a reason. Just upstream is Rainbow Falls in case you are bored with looking at clear water, and fancy a spot of color in it.
