Slieve Binnian

Slieve Binnian is a mountain in County Down, Northern Ireland, reaching about 747 meters with a broad flat summit. Distinctive granite formations called North and South Tors mark its ridge line and define the peak from many angles.

The Mourne Wall, built in the 19th century to contain sheep grazing lands, runs across the mountain slopes and passes through the summit. This stone wall remains a visible feature of the landscape today.

The name comes from Irish 'Sliabh Binneáin', meaning mountain of the little peaks, reflecting the area's connection to Irish language and tradition.

A circular walk of about 11 kilometers starts from Carrick Little car park, passing through varied terrain with stony paths and mountain tracks. Sturdy footwear is recommended, and be prepared for changing weather conditions.

Beneath the mountain lies a 4-kilometer tunnel system built with remarkable precision. The two construction teams digging from opposite sides met with an alignment error of only 5 centimeters.
