People are being asked to be mindful of others when parking in Rossmore Park.
Images were posted online yesterday that showed a large number of cars double parking or being left along the main entrance avenue.
There's concern that this is making the Monaghan town park more dangerous for pedestrians, runners and cyclists.
Sinead O'Reilly from Friends of Rossmore Park said it's great to see the park so busy, but there's concern about the risks it could pose.
