The Long Mountain Ridge is along ridge of land that runs from Ballymoney in the north to Randalstown in the south. It was created by the erosion of weaker bands of basalt located on either side of the feature. Due to this action, Long Mountain now forms quite a unique feature in comparison to the surrounding landscape. The land is quite fertile due to the weathering of Antrim Lavas.
A variation in slope, especially on the sides of the feature, greatly influences the size of field. However on top of the feature where the land is much flatter, field size is much bigger. There also is a mixture of hedges, shelterbelts, moorland scrub and Craigs Wood Conifer Plantation as well as the presence of archaeological features.
