Slieve Gallion Walk — Sperrins

Embark on the Slieve Gallion Walk, a moderate hike spanning 10.2 miles (16.5 km) with a significant elevation gain of 1591 feet (485 metres), typically taking around 4 hours and 51 minutes to complete. You will journey through the atmospheric Iniscarn Forest, featuring ancient oak and coniferous woodlands, before ascending steep mountainsides and open moorland. From the two distinct summits, you can enjoy sweeping panoramic views across Lough Neagh, the Mourne Mountains, and the wider Sperrin Mountains on a clear day.

This route is suitable for those with good fitness, as it involves a considerable ascent and sections of steep, uneven ground. Sturdy walking boots with good ankle support are highly recommended to navigate the varied terrain, which includes rocky paths and areas of blanket bog. Prepare for a rewarding challenge that offers diverse landscapes and expansive vistas throughout your journey.

Slieve Gallion is a site of geological significance, formed as a volcanic plug, and holds the distinction of being the easternmost peak of the Sperrin Mountains. The area is also home to unique ancient peat deposits, some dating back 10,000 years, making it a site of scientific interest. Local folklore adds to its mystique, with a cairn on the basalt mountaintop believed to be the burial place of King Colla Uaís.
