Just found this thread while researching Ponyville Geography. it seems the Everfree forest is to the east in show maps while a some fanmade ones seem to place it to the West. This is a map from the official show
And here it is in the West
After cross referencing and looking at multiple sources it seems most likely that the main part of the everfree where fluttershy's cottage is to the East but it reaches back up to the west like a horse shoe if you will. This also makes part of the Everfree close to Sweet Apple Acres.
