Hi,
Google “least cost path”.  You should find something.

I also have a DEM that I could use if that was possible.  Is there a plugin available to assist with this?  Accuracy isn’t all that important as it’s for a potential road in a forestry block, but Id like a shp file produced that I could then load into my drone to fly the route before more precise planning took place.
