How the National Trust Saved Cornwall's Coast – The Story of Neptune
The West Country, as all of us who live here are only too aware, has a lot going for it. The peninsula is adorned with a plethora of fine features, from fertile vales to the great high moors.
But it is the sea coast which acts as the most important mantle upon which the favourite jewels of our crown are displayed.
Ask any visitor which single element of the West Country he or she identifies with first and foremost and the reply will probably have something to do with the seaside.
Unspoilt coves, big broad surfing beaches, picturesque harbours, noble headlands…
Most visitors to the region will spend at least some time at the coast and it is generally recognised that the shores of the West Country are among the finest in England.
Yet there was a time when much of that coastline was under threat from development. And it was partly to prevent that happening that the National Trust launched one of Britain's most important conservation campaigns.
It was called Neptune.
The campaign that set out to save the coast
The National Trust's Neptune campaign was launched in May 1965 by Conrad Rawnsley, grandson of one of the Trust's founders, with the aim of preventing inappropriate development along unspoilt coasts.
At the time, a survey of the 3,000 miles of coastline in England, Wales and Northern Ireland found that approximately a third was already ruined and another third was considered to be of little interest. The remaining third – around 900 miles – was regarded as coastline important enough to save.
The original target was to raise £2 million through voluntary subscriptions. It was an ambitious undertaking.
But Neptune proved to be hugely successful, thanks to the generosity of landowners who gifted property, and members of the public who left money in their wills or made donations.
Over the decades the campaign has raised enormous sums and enabled the Trust to acquire and protect hundreds of miles of coastline.
The figures have grown dramatically since I first wrote about Neptune. On its 60th anniversary in 2025, the National Trust revealed that new detailed mapping showed it was caring for 896 miles of coastline in England, Wales and Northern Ireland – more than 10 per cent of the total. The campaign had raised more than £114 million.
And nowhere has the story been more impressive than Cornwall.
Saving Cornwall's wild coastline
More than a third of Cornwall's much-celebrated coastline came under National Trust ownership through the Neptune programme and other associated acquisitions.
That matters because owning a piece of coast is not simply a question of putting up a sign and collecting the car-parking money.
The Trust has to manage farms, footpaths, cliffs, beaches, wildlife, historic monuments and buildings – and it has to cope with the increasingly obvious effects of coastal erosion and a changing climate.
The result is a remarkable patchwork of protected land stretching around the Cornish peninsula.
From Boscastle, Crackington Haven and the cliffs between Duckpool and Sandymouth in the north, to the Dodman, Fowey and the Lizard; from Godrevy and the coast around St Ives to Pendeen, Penberth and Whitesand Bay, Neptune has helped create a chain of protected coastal landscapes.
Some acquisitions are relatively small. Others are enormous.
At Bosigran and Carn Galver, for instance, the Trust acquired more than 200 hectares stretching along the coast, while on the Lizard the holdings include substantial areas of farmland, cliffs and headland.
At St Eval, the Trust's land forms the wild backdrop to Bedruthan Steps.
Around Lansallos, Lantic Bay and Lantivet Bay, it protects another stretch of extraordinarily beautiful south Cornwall coast.
And on the far west coast, the holdings around Bollowall, Carn Gloose and Cot Valley include cliffs and farmland once intensively mined for tin.
These are not simply dots on a map.
Put them together and they form a great continuous story of Cornwall's coastline – one in which the sea, the landscape, wildlife, farming, mining history and tourism are all intertwined.

But what does owning the coast actually mean?
That was something I wanted to find out when, during my years as a Western Morning News feature writer, I was invited by the National Trust to visit one of its most famous coastal holdings.
We met at Godrevy.
I was there to talk to Nick Lawrence, then the Trust's assistant regional director, about what Neptune had achieved and what it might mean for the future.
Godrevy was a particularly good place to have that conversation because, in one relatively small coastal holding, the headland contains so many examples of the issues, opportunities and problems which come with owning and managing a great piece of the Cornish coast.
Within minutes of arriving it became clear just how live those issues could be.
It was a sunny but freezing weekday morning in February, yet the car park was already half full and the beach café was packed.
As we enjoyed a coffee and a chat before setting off for a walk, a fellow diner accosted Nick and demanded to know whether the Trust intended to purchase a wildlife-rich coastal property next door to Godrevy.
It was not for the first time that day that I realised just how important National Trust coastal ownership is to so many people.

Godrevy – a case study in looking after the coast
Nick explained that the early days of Neptune had been about acquiring more and more coastal holdings. But things had changed.
The Trust was still keen to save crucially important sections of shoreline when the opportunity arose, but with so many coastal properties already on its books it increasingly had to concentrate on looking after the landscapes it owned and managed.
And that meant dealing with people as well as nature.
“The original vision was clear: let's buy unspoilt coastline because we need to protect it,” Nick told me as we set out on our walk around Godrevy.
“They were very proactive at a time when the National Trust was growing quickly and over a short period of time, we were very successful.”
But, he said, Neptune had evolved. The acquisition of land was now only part of the equation. It was equally about involving people in what the Trust did and providing experiences along the coast which people loved.
That is a particularly important point in Cornwall, where the coast is not some remote wilderness visited by a handful of conservationists.
Millions of people come here.
They come to surf, swim, walk, picnic, watch wildlife, photograph the landscape and simply sit and stare at the sea.
The South West Coast Path runs through many of these protected landscapes, and the path itself has become an important part of Cornwall's tourism economy.
The cost of keeping the coast open
At Godrevy, Nick pointed to an area of eroded cliff where around 30 feet of steps leading down to the shore had disappeared during a single winter. The problem was not merely aesthetic.
The Trust had responsibilities for keeping access safe, while the road serving the farm, café and car parks was itself getting dangerously close to the eroding cliff.
“It is our job, but also our statutory responsibility, to make the beaches safe,” Nick told me.
Even then, the cost of dealing with one relatively small erosion problem could run into thousands of pounds.
And that was more than a decade ago. Today the problem is even more obvious.
The National Trust says that coastal erosion at Godrevy is now undermining the single access road to the headland and that surveys suggest the road could become unsafe within a relatively short timeframe. In June 2026 the Trust replaced an 80-metre boardwalk which had been installed in 2018 and had reached the end of its useful life after years of heavy use and exposure.
In other words, the things Nick and I were talking about all those years ago have not gone away. They have become more urgent.
The changing face of Neptune
“Mullion Cove is a classic example,” Nick told me during our conversation.
The Trust had inherited the harbour, but with little endowment to pay for its upkeep. Repairs were expensive and the opportunities to generate income from the harbour were limited.
Then there was the increasing storminess of the weather.
“The cost of looking after these places is increasing,” he said.
“We have to ask: how sustainable is this? What is the long term picture? What's going to happen?”
That is perhaps the great question facing the Neptune campaign today.
It is relatively easy to understand why a charity should want to buy a beautiful piece of unspoilt coastline before somebody builds on it.
It is considerably harder to explain how that charity will continue to pay for its maintenance for decades and centuries afterwards.
The Trust's answer has increasingly involved finding ways of generating income from the landscapes it looks after while trying not to damage the very qualities which make them special.
At Godrevy, for example, that can mean car parking and catering as well as encouraging people to understand why the landscape needs their support.
The Trust also has to balance farming with environmental concerns. Many of its coastal farms are tenanted, and asking farmers to manage land in more environmentally friendly ways can reduce the rental income the charity receives.
So the business of conservation is not simply about buying land. It is about making that land sustainable.
A coastline under pressure
When I visited Godrevy, one of the most interesting things Nick talked about was the way small acquisitions made over many years could eventually produce a much bigger environmental benefit.
The Lizard was his example. The Trust might have owned only a small area to begin with, but as more parcels of land were acquired, the cumulative impact became much greater.
New footpaths could be created. Power cables could be put underground. Larger areas could be managed together. Wildlife could benefit. And visitors could enjoy a more coherent landscape.
He mentioned the return of the chough to the Lizard as one example of the way conservation successes could develop, although he was careful to point out that this was not something the National Trust had achieved on its own. Wildlife organisations, councils, private landowners and others had all played their part.
That is another important lesson from Neptune.
Saving the coast is rarely the work of one organisation alone.
Why the Cornish coast belongs to all of us
There is something rather wonderful about the fact that so much of Britain's coastline remains open to ordinary people.
Here in the UK we can be very gleeful indeed when it comes to our universal love of beaches and coasts.
Most of the nation's shoreline is accessible to one and all. Private signs banning people from beaches are relatively unusual.
Compare that with some heavily developed Mediterranean coastlines and the difference becomes stark.
I remember making this comparison in my original article because it seemed so extraordinary that a peninsula like Cornwall could still have hundreds of miles of openly accessible seaside.
And a large proportion of that coast is owned and managed by a charity whose stated purpose is to protect it for future generations.
That is something easily taken for granted. Perhaps we shouldn't.
The future of Cornwall's beaches
When I wrote those original articles, the great challenge seemed to be protecting the coast from inappropriate development.
Today that challenge remains, but it has been joined by another one which is impossible to ignore: climate change and coastal erosion.
The National Trust's current work at Godrevy illustrates the point perfectly.
The headland is still hugely popular with visitors, but the Trust now says that rising sea levels and more extreme weather are accelerating coastal erosion. At the same time, large numbers of visitors bring their own pressures, particularly on fragile habitats and archaeological features.
The answer cannot simply be to keep rebuilding everything exactly where it has always stood. Sometimes paths will have to move. Sometimes access roads will have to change.
Sometimes buildings or coastal structures will become impossible to maintain in their present form.
And sometimes the best thing conservationists can do is allow the coastline to change naturally while finding new ways for people to experience it safely.
That is a very different sort of conservation from the one envisaged when Neptune began in 1965. Yet the underlying principle remains remarkably similar.
Keep the coast special. Keep it accessible. Look after its wildlife and landscape.
And make sure that future generations can experience the same sense of wonder that we have today.
Cornwall's coast – a national treasure
There are few things more reassuring than standing on a Cornish headland and looking out across the Atlantic.
The cliffs may be crumbling. The paths may need moving. The weather may be becoming more extreme. The cost of maintaining harbours, beaches, farms and footpaths may be rising rapidly.
But the great achievement of Neptune is that so much of this magnificent coastline remains in safe hands.
The campaign began with the straightforward idea that unspoilt coast should be protected from inappropriate development.
More than sixty years later, that principle has evolved into something much bigger.
It is about nature conservation.
It is about public access.
It is about farming and wildlife.
It is about tourism and local communities.
It is about the South West Coast Path and the millions of people who walk it.
The scale of that responsibility is extraordinary. The National Trust says it is guardian of more than 400 miles of coastline in the South West alone, including approximately 295 miles – almost a third – of the 630-mile South West Coast Path, which runs from Minehead to Poole Harbour.
And, increasingly, it is about working out how a coastline can be cared for when the sea itself is changing.
The costs have become enormous. The National Trust currently estimates that each mile of coastline costs around £3,000 a year to maintain. Multiply that across hundreds of miles and it becomes easier to understand why looking after the coast is such a financial as well as an environmental challenge.
When I stood at Godrevy with Nick Lawrence all those years ago, a section of cliff had already disappeared and the Trust was wrestling with the cost of keeping people safely connected with the coast.
Today, the erosion is still happening. Indeed, the problem has become considerably more serious. The National Trust now says that recent coastal erosion and geological surveys suggest the access road to Godrevy headland could become unsafe within the next five years. In June 2026 the Trust replaced the 80-metre boardwalk leading towards the headland, which had been installed in 2018 and had reached the end of its useful life after hundreds of thousands of visitors and years of exposure to the harsh coastal conditions.
And the National Trust is once again having to look ahead and ask what Godrevy will look like in the future.
Perhaps that is the real legacy of Neptune.
Not that Cornwall's coastline has been frozen in time – because it hasn't, and it never could be. But that generations of people have been given the chance to enjoy it, and that there is a continuing effort to make sure they can do so long into the future.
Millions of country lovers and seaside fans would agree that is something worth protecting.
