I live in Waikiki, a block from this beach. We go all the time and swim in "the ponds", the walled off areas perfect for non-swimmers, kids and folks who don't want to be in over their heads. The water is OK, could be cleaner, lots of sunscreen on the surface. Over the wall is clean water, fairly shallow conditions and lots of rocks. Down by the Moana Surfrider and Royal Hawaiian Hotel, the beaches are really nice, great for body surfing, surfing lessons, etc. The beaches in Waikiki are always busy with lots to see! If you want cleaner more peaceful beaches, head out of town.
