Six Flags America in Maryland is closing permanently at the end of its 2025 season, including its waterpark Hurricane Harbor Maryland. Additionally, Six Flags announced the planned closure of its Great America park in Santa Clara, California at the end of its 2027 season, a year before the lease ends. These closures are part of a strategic decision as both parks rank low on profitability and are not considered a fit with the company's long-term growth plans. Six Flags America has experienced reduced operations and maintenance lately as its final season winds down. The Maryland site is set to be sold for redevelopment after closure.
