It's said to be dangerous due to the currents.
Right - I just was thinking it had more of a drop off which would make it harder to immediately get out of the water and then be moved by a strong current. Perhaps at certain spots it was deeper - but from photo appearances, it doesn't look more than waist-deep on an adult to me (all opinion, i've never been there). It also looks very calm in almost all the photos, but we can't know if that was the case that evening unless someone else was awake.
