Spouting horn is a neat thing to go and watch. It is an old lava tube that when the tide is coming in and the waves start to crash in, it fills up and spouts out this mass of water. We watched it for awhile close up and then when we drove away we look behind us and saw that you could see the sunsetting. Then we realized that the spouting horn was jumping up still and looked like it was trying to touch the sun. Such a cool thing to watch.
