Plans for a zip wire at Honister Slate Mine have been resubmitted.
Two previous schemes to run a wire more than 1000m down the side of Fleetwith Pike have been turned down by Lake District planners but the latest is also needed to help recover tonnes of stone from the mine.
The Lake District National Park Authority has confirmed a third application has now been lodged.
A spokeswoman for the authority said: "We have received the application and it is just in the process with the planning team at the moment."
The application is yet to appear in the online portal but is soon due to be published.
Mine owner Jan Wilkinson has previously said the National Park has to strike a balance between providing conservation and sustainability for the area. The wire, she said, help recover tonnes of walling stone that is needed for construction across the national park and which is in short supply.
Permission for zip wire schemes at Honister was refused in 2011 and 2013.
Both were rejected on the grounds that the zip wire would harm the "remoteness, tranquility and wildness" of the area.
There were also concerns regarding the Honister Crag Site of Special Scientific Interest but in both cases it could not be proven whether or not the development would have an adverse effect on the designated site.
Jan has also told the News & Star the new application has an environmental aspect, taking people off the hillside opposed to them walking and therefore avoiding erosion.
It comes as a consultation on plans for a £1.8m activity hub at Thirlmere is due to end on Friday.
Treetop Trek, the firm behind the plans - for two zip lines and an 18km cycleway - insists the Lake District should be for everyone.
It says the development would attract an extra 127,000 visitors a year and create the equivalent of 28 full-times jobs.
Liberal democrat county councillor Will Clark thinks the cycleway would be a worthwhile standalone project but he said that Thirlmere was the wrong place for a zip wire development.
He said opposition from organisations including the National Trust, British Mountaineering Council, Open Spaces Society and Friends of The Lake District "speaks volumes."
“This project would lead to the tranquillity of the valley being shattered, a wild landscape being lost and I also have grave concerns about the safety of the project," said Mr Clark.
“The Lake District National Park Authority are proud to boast about the areas recent accreditation of World Heritage Status. Surely this means conserving and enhancing an area of natural beauty and not making it into a busy theme park."
