Proposals for a 31-turbine wind farm and another with 17 turbines face opposition from Highland Council.
Eurus Energy UK is planning the largest of the projects at Balnespick Estate and Forestry Commission Scotland land, near Tomatin.
Nan Clach Limited - a consortium between Cawdor Estates and Infinery - also has plans for a site near Tomatin.
Council officers have recommended that councillors oppose the projects because they would impact on the landscape.
The surrounding area includes Dava Moor and Lochindorb where there is a ruined castle on an island on a loch.
Also nearby are the Findhorn Terraces, the highest set of river terraces in Scotland.
Officers also said the proposals go against the council's Highland Structure Plan.
Members of Nairn, Badenoch and Strathspey planning applications committee will visit the proposed sites on Monday.
