Although termed a forest the area has very few trees. It is in fact a deer forest; an area maintained by the owners primarily for deer stalking. Three estates cover the principal area of the forest. Dundonnell Estate (134 km2) covers the northwest part of the forest, including the northwestern flanks of An Teallach, whilst Eilean Darach estate covers 262 km2 in the northeast, including the northeast flank of An Teallach. The majority of the area, including all the southern and central sections, forms the 323 km2Letterewe estate.
