Pacific Beach Boardwalk
The long, narrow cement Pacific Beach boardwalk lines the beach and is full of skateboarders, rollerbladers, runners and bike riders. The boardwalk extends for three miles down to Mission Beach. This is a favorite place for college students from UCSD and SDSU, and young adults to exercise and have fun.
There are many interesting shops, restaurants, taco stands, and beach rental stores, especially at the northern end close to Grand Avenue, to enjoy on your Pacific Beach San Diego vacation.(source San Diego beaches and adventures)
