Carol Gillingham would like to see people stop playing on sand dunes in Kāpiti's Queen Elizabeth Park.
"I'm not having a go at anyone, I just want Joe Citizen who comes to the beach like I do, to think before they climb the dunes.
"There's plenty of other ways of having fun at the beach."
Her interest in highlighting the dunes protection was sparked after seeing "a father, two boys and a dog" playing on a sand dune near the Raumati South entrance of the park.
She acknowledged people had played on sand dunes over time and it was "probably a Kiwi thing" but times were different now.
"I just want people to stay off the dunes.
"I want them to realise that, although we grew up and it was always okay to climb up sand dunes, these sand dunes have been eroded by the sea and are going to get more eroded with rising sea levels and every time there's a large storm.
"People need to realise how fragile the dunes are and stay off them.
"And if you're down here with your kids, don't let them climb the dunes, and if they come here by themselves maybe have a conversation beforehand."
Carol, from Raumati South, said there were signs along part the coastal track saying 'Surf the Waves, Not the Dunes'.
"That is really pertinent.
"They put those signs up when they put the posts and wire fence along part of the track to stop putting hooning off down sand dunes wherever they liked, because there are allotted access points to the beach."
She said part of the coastal track was already heavily eroded and only "about two inches of sand track left".
Carol, who enjoys walking along the beach and in the park, was going to contact the Wellington Regional Council to suggest putting some of the signs near the Raumati South entrance.
"The signs would remind people when they're down there."
