A new pedestrian route stretching around the whole shoreline of England is being officially inaugurated.
At 2,689 miles long, it has been declared the longest officially maintained coastal walking route in the world, per the public agency that established it.
Its official designation is quite a trek - King Charles III England Coast Path - but for the very first time, it creates a seamless trail, enabling hikers to explore England's shoreline mile by mile.
Throughout its length, it passes through some of the country's most spectacular and eclectic scenery, from salt marshes and sandy beaches to chalk faces, dunes and quaint seaside villages.
One standout feature is the famous white cliffs of the Seven Sisters in a southern county, which also constitutes a newly designated protected natural area.
Much of the new shoreline path was previously in place, but over 1,000 miles of additional routes have been created, and many other sections upgraded. Trails have been resurfaced, stiles removed, wooden walkways constructed and crossings erected.
The project was first proposed under a previous government, and it has taken almost twenty years and several governments to get to this stage.
Approximately 80% of the route is now open and the bulk of the rest is expected to be finished by the end of the year.
"It's truly wonderful - the best thing I will accomplish in my professional career," remarked the person who headed the project.
Forging the route required fresh laws as well as a long time of detailed strategy and extensive work along the shoreline to establish a obvious and uninterrupted trail.
In many places, new rights of access have granted entry to terrain that was previously inaccessible to the walkers - including coves, dunes and cliff-tops between the trail and the sea.
Ease of access for those with limited mobility has been upgraded so that a wider audience can enjoy parts of the trail.
Gaps in the existing network of public paths have been bridged with a priority on bringing the route closer to the shore and linking parts of coastline that had not yet been joined by a single route.
However in a handful of locations, walkers must for a short time step away from the path. In the north-western region, for example, a vessel across the Mersey is required to follow the route.
A particular section in south Devon is notably challenging. At the River Erme, there is not a crossing or boat, and the land inland is in private hands. Hikers must therefore roll up their trousers and wade across the river within an 60-minute period around low tide.
"That's all part of the adventure," notes the project lead.
The path has been designed with the heavier rains and rising seas that a warming planet is expected to create in mind.
For the initial occasion in the country's statutes, there is a mechanism for the trail to be shifted away from the coast – termed "retreated" – if the shore retreats or moves.
This permits the trail to adjust to the dynamic coast and is intended to ensure that the shoreline route remains unbroken and usable for future walkers.
Not long ago have illustrated how dynamic the trail can be. A large section of the path on the cliff tops outside a coastal town in Dorset was severed after substantial rainfall caused a collapse.
"The path was shut and a alternative route was put in place," said a official for that area. "The team promptly negotiated a 15-metre move with the property owner, and within a short time the path was open again."
A prominent walking charity has been advocating for enhanced access to England's shoreline for many years. A director labels the new path as "transformational".
"It creates a band of open land from the trail to the high water mark, so that implies you can leave the trail to go and roam the sands," they say. "You can picnic - and on an island nation you can truly appreciate our coast."
The route also suggests the possibility of a unbroken coastal walk around the whole British Isles.
The new English coast path links with the Welsh coastal trail - an long path following the coast of Wales. It was completed over a in the early 2010s and was the first path in the world to track an entire country's shore.
There is lacking an official managed shoreline path in Scotland, though a great deal of the coast is open to the public thanks to long-standing "access legislation. Figures of its mainland coastline vary but it is often put at five thousand five hundred miles.
Combined, a end-to-end coastal walk around Great Britain would therefore amount to some nine thousand miles. At an average pace of 15 miles a day, it would need {almost two years|n
