A new footpath winding around the entire shoreline of England is being formally opened.
With a length of 2,689 miles long, it is the most extensive officially maintained shoreline path in the globe, as stated by the government body that developed it.
The trail's title is a mouthful - King Charles III England Coast Path - but for the first time, it forms a continuous route, permitting ramblers to traverse England's seaside at their own pace.
Throughout its length, it meanders through some of the country's most picturesque and eclectic landscapes, from tidal wetlands and golden shores to cliffs, dunes and charming harbour settlements.
A key attraction is the renowned white cliffs of the a series of cliffs in a southern county, which also constitutes a recently announced National Nature Reserve.
A significant portion of the recently completed trail had been established, but over 1,000 miles of new paths have been forged, and countless stretches improved. Trails have been repaired, fences eliminated, boardwalks installed and footbridges erected.
The initiative was first proposed under a past leadership, and it has required 18 years and several governments to reach this milestone.
About 80% of the trail is now open and the majority of the remainder is scheduled to be finished by the end of the year.
"It is fantastic - the greatest achievement I will accomplish in my time in this role," remarked the person who headed the initiative.
Creating the route necessitated updated statutes as well as years of careful planning and extensive work along the shoreline to define a obvious and linked footpath.
In many places, fresh public access privileges have opened terrain that was formerly private to the general populace - including sandy shores, sand dunes and cliff edges between the trail and the ocean.
Accessibility for those with reduced mobility has been upgraded so that additional individuals can walk sections of the path.
Discontinuities in the established web of trails have been filled with a priority on bringing the route right alongside the sea and connecting sections of shoreline that had not yet been connected by a unified route.
But in a couple of spots, walkers must for a short time step away from the trail. In north-west England, for example, a vessel across the Mersey is needed to pursue the trail.
A particular section in a southwestern county is notably adventurous. At the River Erme, there is no bridge or ferry, and the terrain further upstream is not public. Walkers must therefore roll up their trousers and wade across the river within an hour either side of low tide.
"That's all part of the journey," comments the project lead.
The route has been designed with the heavier rains and higher sea levels that a warming planet is expected to bring as a consideration.
For the first time in national legislation, there is a mechanism for the route to be shifted away from the coast – called "retreated" – if the coastline retreats or changes.
This permits the trail to adjust to the changing coast and aims to ensure that the shoreline route remains accessible and usable for posterity.
The past month have shown how changeable the route can be. A large section of the trail on the cliff tops outside Charmouth in Dorset was lost after severe storms caused a collapse.
"The path was shut and a diversion was put in place," explains a manager for that region. "The team swiftly negotiated a 15-metre move with the property owner, and within a short time the path was accessible once more."
A leading walking charity has been lobbying for enhanced access to England's coastline for many years. A representative characterises the inaugurated route as "revolutionary".
"It creates a zone of public space from the trail to the tide line, so that means you can step off the trail to go and walk on the sands," they say. "It allows for picnics - and on an archipelago you can for the first time appreciate our coast."
The trail also opens up the possibility of a seamless shoreline hike around the entire UK coastline.
The freshly opened England trail connects to the Wales Coast Path - an extensive path following the coast of Wales. It was completed over a decade ago and was the initial trail in the globe to trace an entire national coastline.
There is not one unified designated route in the north, though a great deal of the shoreline is available thanks to established "access legislation. Estimates of its shore length differ but it is often put at several thousand miles.
When added up, a end-to-end coastal walk around the UK would therefore reach some nine thousand miles. At an average pace of 15 miles per day, it would require {almost two years|n
