Clwyd MS Darren Millar has written to Denbighshire County Council urging them to scrap their plans for an overnight Motorhome Aire on a prominent part of Rhyl promenade.
Last month, Denbighshire County Council announced that it hopes to build six motor home overnight stops, with two in Rhyl and others in Prestatyn, Ruthin, Corwen, and Llangollen.
One of the sites proposed for Rhyl, on Marine Drive (East Rhyl), has been opposed by local residents and councillors Justine Evans and Brian Jones, who believe it will spoil the seafront and take away a much-used community space.
Residents on Marine Drive have been leading the 'Save Marine Drive Playing Fields' campaign against the proposal, which has received support from people across Rhyl.
Last Tuesday evening they held a well-attended public meeting at the Sun Verge to discuss protecting the green space.
On Thursday, Darren met will those leading the campaign and subsequently sent a letter to Denbighshire County Council urging them to review their plans for a Motorhome Aire on such a prominent, well-used site.
Speaking afterwards, he said:
"Without doubt Rhyl's biggest asset is its beach and wonderful promenade. We must protect these assets at all costs.
"Motorhome Aires are good in the right location, but this is not the right location.
"This is a beautiful un-spoilt spot which has been enjoyed by generations, and we need to ensure that it remains there for generations to come.
"On meeting some of the residents leading the campaign today, it was clear just how passionate they are about safeguarding this important community space.
"The Motorhome Aire may well generate an income for the Council, but there are plenty of campsites in the area already and we cannot afford to lose a much-loved and well-used community green space.
"I fully support local residents and will do everything within my power to make Denbighshire County Council see sense and scrap these plans."
Rhyl East County Cllr Justine Evans, who has been working with the residents in a bid to safeguard the greenspace, said:
"At a time when Denbighshire County Council is spending money creating new green spaces in Rhyl, such as at the Pocket Park at the bottom of the High Street, it seems ludicrous for them to be even considering getting rid of one on a prime site on Rhyl Promenade.
"Before it became the Balfour Beatty compound seven years ago, the proposed site was a vibrant community space enjoyed by people of all ages.
"It is crucial that we protect this shared community resource because once green spaces like this are lost, they tend to never be replaced."
