Picking it up, you notice that it's not a very fine grain, but instead more like small pebble sized. It's mostly smooth though, from the water breaking down those edges over time. There were several people on the beach, as the shape of this was very much like a wave pool. All of the water was funneled into this little cove of sorts. It was awesome. We stayed for just a few minutes, and proceeded up some rocks, and things just kept looking better.
