NO, NO, NO - these rocks on my picture just divide Coronado Beach into two parts: eastern and western.
As I said before I have never seen rocky beaches with people sitting/lying on the rocks (hehe) in the USA, is it exclusively European custom? Are these rocks put for European tourists? Hehe.
Not all beaches I visited along USA Pacific Coast were clean out of the season that is in April/May. But Coronado Beach was very clean (at least close to the Hotel Del Coronado) - do they clean it all the year round?
There were numerous trashes along the beach although there were few people.
Generally, the whole Coronado seems to be a very clean area.
I don't know but I saw lifeguards' vehicles driving along the Coronado Beach in April. Hmm... there were not female - lifeguards, I wonder why?
