California theme parks have begun to reopen their gates after being closed for more than a year due to the pandemic. At first, only those living in California were allowed to visit the theme parks. Now state officials are welcoming out of state visitors with restrictions. The California Department of Public Health recently revised its Blueprint for a Safer Economy, which would allow out of state visitors so long as they are fully vaccinated.
While it is now okay for out of state visitors to visit certain theme parks in California, you may want to check what each park is doing. Sea World was the first to allow out of state visitors who are fully vaccinated. Disneyland Resort has not changed its policy, and will be restricted to California residents for now. Disneyland and Disney California Adventure will reopen on April 30, while Knott's Berry Farm will reopen on May 6 for its season passholders, and May 21 for all other guests. California's Great America in Santa Clara will reopen on May 22. Universal Studios Hollywood, Sea World, and Six Flags Magic Mountain are now open.
