Campaigners are to ask Prince Charles to support their fight to stop a new windfarm being built off the north Wales coast.
The turbines would be sited around nine miles off the coast
The group Save our Seascape (SOS) is opposing plans to build 200 wind turbines nine miles out to sea.
It says the giant turbines will mean magnificent sea views from Anglesey to Prestatyn are lost forever.
However, the energy company behind the Gwynt y Môr scheme says it understands concerns and is addressing them.
Npower renewables put plans for the windfarm, which would stretch from Prestatyn in the east to Penrhyn Bay in the west, on public display last September.
The company currently has a smaller project of 30 turbines called North Hoyle four miles of the coast of Rhyl.
It has not yet decided finally whether to submit a planning application
If Gwynt y Môr does go ahead, it will form part of the second round of larger offshore windfarm developments in the seas around UK, generating enough electricity each year to meet the demand of around 500,000 homes.
But S.O.S said the area's natural beauty will be lost if the scheme goes ahead. It is approaching people in Wirral and North Merseyside to involve them in the campaign and plans to write to Prince Charles to seek his support for their campaign.
Member John Lawson Reay said: "Npower renewables will submit their application to the Department of Trade and Industry in a few months' time.
"Consent could be granted early next year and within two or three years these 200 turbines will become reality.
"It means the magnificent sea views from Anglesey to Prestatyn will be lost forever.
Campaigners are to ask Prince Charles for his support
"It's tantamount to the murder of north Wales' biggest asset - its natural beauty," he said.
The campaign group said it was not against renewable energy, rather against wind turbines.
It is asking the government to look at alternatives such as tidal power, which it says energy providers admit could be the answer in areas like north Wales.
Richard Frost, a spokesman for Npower renewables, said if they were able to build a proper case for it, the scheme would make a significant contribution to electricity generation.
"We go through a process of consultation and we take pride in so far as we talk to people locally.
"We understand people's concerns and we have to address the views that people bring to us.
"There is no evidence that this would have an adverse effect on tourism," he added.
