Lifestyle Travel Gwen Stefani, Vanessa Hudgens and More Celebs Celebrate Knott's Berry Farm's 100th Anniversary The California theme park reopened to the public on May 21, a year after shutting its doors due to the COVID-19 pandemic By Morgan Smith Updated on May 25, 2021 03:02 PM Share Tweet Pin Email After a year-long closure due to the ongoing COVID-19 pandemic, Knott's Berry Farm is back — and the California theme park has recruited a few famous fans to celebrate both the reopening and its 100th anniversary. Gwen Stefani, Terry Crews, Vanessa Hudgens and more celebrities shared their favorite memories from the park in a new video shared exclusively with PEOPLE, above, ahead of the park's grand reopening on May 21. "I love Knott's so much and I have so many amazing memories there," Hudgens says in the clip. "I remember when 'Ghost Rider' opened up and I rode it with my dad … we did it at least four times in a row, we loved it and I still love it." Jerod Harris/Getty She continues: "Now that he's gone, those are memories I will keep for the rest of my life." Hudgens' father, Greg, died of cancer in 2016. Stefani also treated her adorable sons — Kingston, 15, Zuma, 12, and Apollo, 7 — to a fun day at Knott's Berry Farm in December. "They rode Ghostrider four times and were also seen picking out candy and taffy in Camp Snoopy," an onlooker told PEOPLE at the time. 2021 marks 100 years since Walter and Cordelia Knott began farming 20 acres of land along Highway 39 (now known as Beach Blvd.) in Buena Park, California. In 1930, the pair discovered the boysenberry – a cross between a loganberry, red raspberry and blackberry.

Knott's Berry Farm — which features 40 rides and its Soak City waterpark — will be hosting a 100th-anniversary celebration called "The Knott's Family Reunion" this summer. The month-long event will include live music, special food and drink offerings, new costumed characters and the unveiling of its latest ride, "Bear-y Tales: Return to the Fair," a 4-D interactive dark ride that pays tribute to the classic attraction from 35 years ago.
