Twin Rivers Caravan Park, at Foel, was listed on the online real estate property portal last month, marketed by Colliers International Property Consultants.
But site managers Anthony Ayre and Daniel Shipley have said the caravan park is not up for sale.
Mr Ayre said: "It was incorrectly put on, there has been an apology and it is not for sale.
"It has been taken off Rightmove and so we would like people to be aware of that. Colliers have also pulled it from their site."
The advert on Rightmove had highlighted the 128 holiday static caravan and lodge pitches and said the site includes an outdoor heated swimming pool, bowling green, tennis court, club building with bar and three bed bungalow.
The park was described as "an established holiday park occupying a scenic riverside setting".
The advert said 30 acres of upland ground, overlooking the park, were 'available by separate negotiation'.
