Benglenisky is the lowest of the core Twelve Bens, and only meets the mountain classification of an Arderin. Its relative positioning at the southern end of the range, jutting out on its own ridge, means that it often appears as a scenic backdrop to Ballynahinch Castle and the Ballynahinch Lake, however, it is still overshadowed by its more dramatic neighbour, Benlettery, with its striking pyramidal profile.
