Actually, Coronado Beach's path is probably getting more and more beaten now that it's been voted one of America's best beaches. It has a decidedly relaxed, family atmosphere and a stunning backdrop in the Hotel Del.
When I lived in San Diego, I used to usually go to either Solana Beach or Del Mar (at 19th Street), but Coronado is a great place for families.
If you wish to see more walk along the Coronado Beach towards... Mexico hehe. The border is easy to cross (southwards, southwards hehe).
It seems that Ursula found one beach boy hehe but where are beach girls? :-) Hmmm... what to say, look ladies hehe.
