The trust has filed a petition to the Court of Session, urging for a judicial review of Scotland Energy Minister Fergus Ewing’s decision to approve the project.
In June 2014, the Scottish government approved SSE Renewables’ plans to build the Stronelairg wind farm near Fort Augustus in the Great Glen.
Planned to be built on Garrogie Estate in the Highland Council area, the wind farm will feature 67 turbines with the potential to power about 114,000 homes in the area.
The John Muir Trust chairman John Hutchison said: "Over the past year, the Scottish Government has made ground-breaking progress by adopting the new Wild Land Areas map of Scotland, and, for the first time, recognising wild land as an important national asset.
"However, we believe the decision by the Energy Minister to give the go-ahead to Stronelairg without a Public Local Inquiry is not consistent with Scottish Government measures to protect the best areas of wild land from industrialisation."
If built, the Stronelairg wind farm is expected to deliver up to £30m of community benefits to the Highlands region over the 25-year lifetime of the project.
SSE had originally planned an 83-turbine project at the site but the government reduced the proposal by 16 units in order to minimise landscape and visual impacts.
