More than 40 theme parks across the United States have set 2021 reopening dates after the coronavirus pandemic forced many of the amusement wonderlands to postpone their 2020 season openings or remain closed for the entire year.

Individual states in the U.S. have set their own COVID-19 health and safety reopening guidelines with California theme parks unlikely to return to full operation until spring or summer. Some California theme parks have partially reopened for special events without rides.

U.S. theme parks are hoping 2021 is better than 2020. At the moment, U.S. theme parks fall into three categories: Already opened, tentatively planning to return in the spring or still shuttered without a reopening date set.

Let’s start with what’s already open. All the major theme parks in Florida — Disney, Universal, Busch Gardens, SeaWorld, Legoland. As well as all the big parks in Texas — Six Flags and SeaWorld. Same goes for a few smaller parks around the country — Nickelodeon Universe (New Jersey and Minnesota), Adventuredome (Nevada) and Glenwood Caverns Adventure Park (Colorado).

California, New York, Illinois, Michigan and Massachusetts are the only states that have not allowed theme parks to reopen in the United States, according to the California Attractions and Parks Association.

Most major California theme parks have not set reopening dates — including Disneyland, Universal Studios Hollywood, Knott’s Berry Farm, Six Flags Magic Mountain, Legoland California, Six Flags Discovery Kingdom and Santa Cruz Beach Boardwalk.

SeaWorld San Diego has set a partial reopening date — but under zoo and aquarium guidelines with no rides. California’s Great America, which remained shuttered for all of 2020, is the first California amusement park to set a reopening date.

A couple smaller parks in upstate New York — SeaBreeze and Adventureland — have announced opening plans. A few parks in Illinois — Six Flags Great America and Santa’s Village — have done the same. Likewise for Six Flags New England in Massachusetts and Michigan’s Adventure.

Other New York amusement parks — including Six Flags Great Escape, Six Flags Darien Lake, Luna Park, Deno’s Wonder Wheel and Rye Playland — have not yet set reopening dates. Legoland New York plans to open in 2021 after the new theme park had its 2020 debut delayed by the pandemic.

Several smaller theme parks across the nation have not yet announced reopening dates for 2021 — including Idlewild and Conneaut Lake (Pennsylvania), Holiday World (Indiana), Mt. Olympus (Wisconsin), Lagoon (Utah), Lake Winnepesaukah (Georgia) and Canobie Lake (New Hampshire).

The reopening dates below should be considered tentative at best — as with everything else involving the coronavirus pandemic. Check out Coaster 101 for a continually updated list of U.S. theme park reopening dates.
