Skye's Cuillin Hills and Durinish have been named among 42 Wild Land Areas of Scotland published by Scottish Natural Heritage (SNH).
The areas have been identified as having "high wildness" and include islands, mountain ranges, moorlands and blanket bogs, said the agency.
Among the sites are parts of Jura and also Hoy in Orkney, Breadalbane-Schiehallion in Perth and Kinross and Lochnagar as well as the Skye areas
Peter Hutchinson, SNH's planning and renewables manager, said: "Our Wild Land Areas have a distinct and special character.
"They are part of Scotland's identity and bring broad and significant benefits. For example, they attract many thousands of visitors each year and provide important havens for Scotland's wildlife."
Now public comments are being sought on draft guidance on protecting the areas with consultation running through until April 7.
According to SNH the descriptions were based on extensive field study work and illustrated with photographs and maps.
Landscape conservation charity, the John Muir Trust, has welcomed the publication of the descriptions and draft guidance.
Stuart Brooks, the trust's chief executive, said: "We would applaud the work that SNH has carried out to create vivid and detailed descriptions of each individual wild land area, which examine landscape, ecology, geology, archaeology and current human activity.
"They will help bring to life Scotland's most beautiful, wild and remote places - turning lines on maps into real places."
