Both Cannon Hall Park and Gardens and Elsecar Park received the national accreditation for their work this year.
It’s the first time that Cannon Hall is raising a Green Flag award since the attraction’s £4m Parks for People restoration project began.
Elsecar Park is also celebrating for the 13th consecutive year, with the ever-popular 18-hectare spot - which includes a reservoir, nature reserve and smoke-free play area - once again awarded for its park.
The two sites are among more than 2,000 sites across the county to win the Green Flag in a record-breaking year for the scheme.
Coun Tim Cheetham, cabinet spokesperson for place, said: “Cannon Hall Park and Gardens has always been a treasured place, right back from its creation in the 1700s, becoming a public park in the 1950s, to the present day when visitors regularly come to create special memories.
“Elsecar Park continues to be a firm family favourite and thanks must go to all our staff, and also the Friends of Elsecar Park, who put in so much time and effort to make it the park it is.
“In recent months our parks and open spaces have become more important than ever, for many being a lifeline in difficult times.
“Our dedicated teams have worked tirelessly to ensure that people not only have a safe experience but an enjoyable one and we are delighted that they have been recognised in this way.”
