And that worked for many decades, until the eco-wussies decided that the seals didn't have enough room on the entire rest of the California coast, and decided to banish the humans from enjoying this one protected spot.
My daughter, then about 10, was screamed at by the eco weanies around 2005 for daring to walk across that beach, even after the rope was ordered down and people were using it again.
My sense of "eco-weenies" is impotent delusional controllers. In reality they are more eco-criminals, cloaking themselves in "mother nature righteousness" to control others.
That beach is clearly man made. That the seals also prefer it rather than the natural coast suggests that these sad excuses for creative human beings could to better expending time, effort and expense to create a similar beach for seals. Of course that would require quite a bit more than lip service and posturing.
You don't want her walking where the seals hang anyway. The feces carries pathogens that infect people. Seals will attack a child as well, and can move faster than a child would expect, particularly when surprised.
