An Bord Pleanála has granted planning permission for a multi million euro upgrade of the cable car to Dursey Island on the Beara Peninsula.
It is the country's only cable car service.
Cork County Council has welcomed the Board's decision, saying it will now consult with its project partners, Fáilte Ireland, and following this a decision will be reached as to how best to fund and advance the project.
An estimated cost of €7 million was invested in the project in 2019 when plans were first submitted.
Local Fianna Fail TD Christopher O'Sullivan described the project as "a massive tourism win for west Cork", saying it will boost tourism in the region.
An Bord Pleanála, in granting planning permission to Cork County Council subject to six conditions, acknowledged that without the proper control of visitor numbers, the project could impact negatively on the local environment, and on the flora and fauna in the area.
With this in mind, it said it was granting permission subject to a cap on visitor numbers at 5,000 visitors during July and August.
