i grew up going to balboa, the plus to balboa is not so much the beach, but the arcade place, they have some dinky rides, a place called pizza pete's or pete's pizza that has really good pizza, my DH likens it to new york style. . .
the negatives are the waves, they crash right there practically on the beach. . . and it has the drop off towards the water, and yes as a kid I "rode the beach!" up and down when a wave caught me off guard. . . the plus to this is you do not have to do the shuffle so much cuz the stingrays don't tend to hang out right there. . .
the beach on the other side of the the *****ula is corona del mar, I THINK IS THE NAME, and that has a nice beach, but nothing extra . . if you go to balboa they ahve all those boats that do the bay cruise, on one fo them it takes you past what i call the rocks, but there is a small alcove area where parts of gilligan's island was filmed. . . we thought that was cool . . .
