At the end of last year An Bord Pleanala granted planning permission which which would have seen a new visitor centre established as well as a new cable car to replace the existing system.
The new cable car would be capable of carrying 15 people onto the island but under the planning visitor numbers to the island would be restricted to 5,000 a month.
Friends of the Irish Environment are opposed to the €10 million plan which they say does not fit with the ecological sensitivity of the island and say the scale of the project is too vast.
Tony Lowes Friends of the Irish Environment told RedFM News that there is no management plan in place for the project.
"It's it's one of these mass tourism projects that's completely out of scale. For a remote place like there's the island. There's the problem of the birds which are protected and which had been declining because of the increasing number of tourists. And there's a problem with the capacity, they're planning to be able to move 650 people an hour on and off the island. And this is being done with no management plan and no, no structure to see how we could protect the art. You need your management plan first, and then your project, not the other way around."
Meanwhile, Cork County Council is being urged to rethink its planned upgrade works to Dursey Island's Cable Car to take the economically vital tourist season into consideration.
The current cable car system is set to close in April due to damage sustained during Storm Barra, and will not reopen until November.
Deputy Christopher O'Sullivan is urging the Council to examine hiring local boat operators to maintain the tourist presence during those crucial months.
