A small Scottish island has been put up for sale for £2.5m. Tanera Mor is the largest and only inhabited island in the Summer Isles archipelago, 1.5 miles off the north-west coast of Scotland.

The 800-acre island is currently managed by Lizzie and Richard Williams, who took it on from Mrs Williams's family, the Wilders. The Wilders bought the island in 1996 after selling their dairy farm in Wiltshire.

Lizzie Williams said it is time to give someone else the "privilege of looking after the amazing place".

Talks with the local community over a buyout were held but it has now been put on the open market after the Coigach Community Development Company decided not to pursue the sale.

"After many happy years of calling Tanera home, it is time for someone else to have the privilege of looking after this amazing place," Lizzie Williams said.

"We greatly appreciate the effort made by the local Coigach community to consider the opportunity of taking on Tanera and we fully understand their reasons for deciding not to. We hope that whoever owns the island in the future will enjoy the same warm and co-operative relationship with the community that we have for the past 17 years."

Estate agents CKD Galbraith is handling the sale and said the community group welcomed the opportunity to buy the island but is currently working on renewable energy projects.

CKD described Tanera Mor as a "flourishing tourist enterprise and superb family residence", with a guide price of £2.5m. It has nine residential properties, a cafe, post office and three jetties.

John Bound of CKD Galbraith said: "The chance to own your own Scottish island is extremely rare and with Tanera Mor's thriving tourist enterprise coupled with being a truly spectacular place to live, we expect to receive a lot of interest as it goes on the open market.

"With ongoing support and commitment from the local Coigach community, Tanera Mor offers a truly fantastic prospect for interested parties who will very much have the island's heritage and sustainability at heart as well as a fantastic life style."

The island inspired the book Island Farm by Frank Fraser Darling, who lived in Tanera Mor in the late 1930s and studied the habitat of its bird colonies.
