An ambitious plan, The Dunoon Project, based on a community buyout of the Corlarach forest above the town, could see it become a centre for outdoor activities.
A cable car would be installed to take passengers up the Kilbride Hill which rises above Dunoon to a cafe and observation spot at the top, according to the proposals.
Going down the hill to a base station, there would be the option of a zip-slide ride down the hill over a distance of four kilometres or a trip in an “alpine coaster” – a type of rollercoaster which follows the contours of the land.
Keith Holdt,who prepared the feasibility study, added: “The beauty of Dunoon is that it is right in the path of people coming over to Argyll and Bute.
“There’s lots of people coming through, but there is currently no reason for them to hang around. But this gives them a reason to stay and spend money in the area.”
It is hoped The Dunoon Project would create jobs and bring investment to the area, with asset manager Gresham House expressing an interest.
Backers are now waiting in the wings, ready to invest the millions needed to make the project a reality.
Tony Dalwood, CEO of Gresham House said: “Dunoon is an exciting project.
