Since 2000. The Big Bay Boom July 4th Fireworks Show is back promising another spectacular display over San Diego Bay. Fireworks will be discharged simultaneously from barges placed strategically around the Bay off Shelter Island, Harbor Island, Embarcadero North, Seaport Village, Embarcadero South Marina Park, Coronado Ferry Landing and Imperial Beach. Listen to the simulcast on 105.7 The Walrus FM radio. The impeccably choreographed display will last approximately 17 minutes. Come to the waterfront to watch the show and the Port of San Diego strongly encourages carpooling or taking the San Diego Trolley. Stay tuned for more information about free shuttle and parking locations.
