The water on the upstream side runs through an old lava tube. I'm told (but haven't seen myself) that when the water isn't too rough, you can carefully hike upstream through the tube to see two waterfalls. There's good parking for several cars just past the bridge in the direction away from Hilo (towards Pepeekeo).
