Rising majestically above the lush Antrim landscape, Slemish Mountain is a natural and historical marvel steeped in legend. Located just 1 mile east of the charming village of Broughshane, Slemish captivates visitors with its dramatic presence and fascinating backstory.

Standing at approximately 1,500 feet (437 metres), Slemish is the remnants of a volcanic plug, the hardened core of an ancient volcano that erupted millions of years ago. Over time, wind and rain eroded the surrounding softer rock, leaving behind the rugged peak that dominates the skyline today. Its geological history spans millennia, making it a natural monument to the forces that shaped this landscape.

A Spiritual Connection: Saint Patrick’s Journey

Slemish holds a unique place in Irish culture due to its ties to Saint Patrick, Ireland’s patron saint. According to legend, Patrick was brought to Ireland as a young slave around AD 390 and worked as a shepherd on Slemish Mountain for six years. During his time on the mountain, Patrick found solace in prayer and contemplation amidst the isolation and harsh weather.

It is said that this period of reflection and spiritual awakening shaped his faith, ultimately leading him to escape, return home, and later become a priest. Patrick’s experiences on Slemish deeply influenced his mission to bring Christianity to Ireland, including the establishment of churches across the North, one of which is thought to have been at nearby Skerry Churchyard, a site still visitable today.

Visiting Slemish: A Hiker’s Delight

Slemish is open year-round, attracting walkers, nature lovers, and history enthusiasts alike. The 1.5-kilometre loop walk to the summit and back offers a manageable yet invigorating challenge, taking approximately one hour in good weather. The path, though short, is steep and rocky, requiring sturdy footwear and care, particularly in wet conditions.

Reaching the summit rewards hikers with spectacular panoramic views: the Antrim and Scottish coasts to the east, Lough Neagh and the Sperrin Mountains to the west, and the Bann Valley to the north. Wildlife enthusiasts may spot buzzards, ravens, wheatears, and even the elusive Irish hare.
