California health officials have given Walt Disney Co's Disneyland and other theme parks the go-ahead to reopen at limited capacity from April 1 after a closure of almost a year due to the coronavirus pandemic.
Capacity will be limited to between 15 per cent and 35 per cent, the California Department of Health said on Friday.
Masks and other safety measures will be required and the parks initially will be open only to state residents.
Outdoor stadiums and ball parks will also be allowed to reopen at reduced capacity, starting April 1.
Ken Potrock, president of the Disneyland Resort, said the decision meant "getting thousands of people back to work and greatly helping neighboring businesses and our entire community".
"With responsible Disney safety protocols already implemented around the world, we can't wait to welcome our guests back," Potrock said.
He did not give a date for the reopening of Disneyland in the southern California city of Anaheim.
Disney in September said it was furloughing about 28,000 workers, mostly across its US theme parks in California and Florida.
Walt Disney World in Florida reopened in July last year, with limited capacity.
Friday's announcement follows a decline in coronavirus cases in California and the rollout of vaccines. A parking lot at Disneyland is being used as a mass vaccination site.
Theme parks such as Disneyland, Universal Studios, Legoland and Knott's Berry Farm protested strongly last October when California health officials ruled out any quick reopening of their attractions.
