Key Aspects:
- Carnival Cruise Line is an official sponsor of Big Bay Boom on July 4, 2026.
- The event in San Diego Bay is the largest fireworks show on the West Coast.
- Carnival Luminosa, Radiance, and Firenze will all be on hand for the show.
With 2026 the year the United States will celebrate its semiquincentennial (250th) birthday, it’s perfectly natural that America’s cruise line would get into the fun with its Fun Ship fleet.
Carnival Cruise Line will join in the festivities in a big way on the West Coast as the official cruise line sponsor of the Big Bay Boom, the celebration at the Port of San Diego. This will be the largest Fourth of July fireworks display on the West Coast, with a full day of outstanding programming and events leading up to the show.
Carnival will be part of the countdown activities before the show blasts off at 9 p.m., and the brand’s image and slogans will be featured throughout the day.
Furthermore, Carnival Cruise Line will be supporting various collaborations to support active-duty service members as well as veterans and military families.
“We’re honored to be part of such a historic milestone and iconic event in San Diego,” said Christine Duffy, president of Carnival Cruise Line.
“Being the exclusive cruise line sponsor of the Big Bay Boom gives us a meaningful way to celebrate our connection to this community, to our military families, and to the patriotic spirit that defines Fourth of July.”
On hand will be all three Carnival ships homeported from California at that time: Carnival Radiance, Carnival Firenze, and Carnival Luminosa.
Carnival Radiance will be on a 5-night Mexican Riviera sailing beginning on June 30 in Long Beach and will spend July 4 in Ensenada before departing to head for the celebrations.
Carnival Firenze will just be beginning a 3-night Baja cruise, leaving Long Beach on July 3 and spending July 4 as a fun day at sea.
Carnival Luminosa will be sailing from San Francisco and will depart on July 2 for her holiday sailing, spending July 4 in Ensenada before heading north for San Diego Bay.
Long Beach is just 100 miles north-northwest of San Diego Bay, while Ensenada is roughly 90 miles to the south.
All three ships will anchor in San Diego Bay in plenty of time for the fabulous fireworks, which will be launched from four separate barges for a truly spectacular show.
“We are thrilled to collaborate with Carnival for next year’s Big Bay Boom program and festivities,” said Chair Danielle Moore, Port of San Diego Board of Port Commissioners.
“Along with Carnival, their cruise ship guests, the local community and thousands of visitors, we look forward to enjoying another spectacular fireworks show and memorable Independence Day celebration across San Diego Bay.”
More Fun at Big Bay Boom
In addition to the 20-minute fireworks show choreographed to music, visitors will enjoy live entertainment, children’s activities, food concessions, dinner cruises, concerts, and more before the night lights up at Big Bay Boom.
As many as 500,000 or more people are expected to attend the event with viewing locations at various parks. Several operators are also offering harbor cruises for even more maritime viewing of the big show.
Unfortunately, guests onboard the Carnival cruise ships will not be debarking to spend time in San Diego, but they will certainly have prime viewing locations for the brilliant fireworks show.
