About two metres of the Naze is lost to the sea each year
The walkway, which will double up as sea defences, will include five interpretation boards about the area, its wildlife and the Tower.
Michelle Nye-Brown, committee member of the
Naze Protection Society
and one of the owners of the Grade II-listed
told BBC Essex it was an important moment in their efforts to save the Naze from the North Sea.
"The Tower is the symbol of the town of Walton-on-the-Naze and it would be terrible to lose the iconic building that represents your town to the sea," she said.
"We've been campaigning for a really long time to get some sort of protection up there at the Naze, over 20 years of campaigning.
"It's a major local issue and also for people who like to visit. Obviously it's a real tourist area and people want to see the tower safe, and also some of the Naze as well."
"When [the tower] was built it was actually a quarter of a mile inland, now it only stands 50 metres from the edge," she added.
Naze Tower was built by Trinity House in 1721 as a marker for passing ships
"If we don't hurry up and build crag walk as soon as possible we are going to lose that building to the sea."
Michelle explained the Naze itself was of international importance, but was prone to falling into the sea.
"It's actually made up of fossils and the cliffs there are made up of fossils that are up to 50 million years old," said Michelle.
"There's things like sharks teeth and also shells and it's actually the shells and the section they come from which is called red crag, which is particularly important because they were dated back to the on-set of the last ice age in Europe.
