The terrain is quite varied and can be rugged. You'll encounter intermittent stretches of forest, leading to a climb up a boggy mountainside. The path becomes steeper as you ascend, traversing areas of peaty and rocky ground. Some sections involve minor roads and forest tracks, while the ascent to the summit often involves a steep mountain path. The descent can also be steep, with slippery rocks in wet weather.
No, this running loop is generally considered a challenging or hard run. It requires good to very good fitness due to steep ascents and descents, as well as rocky and muddy sections. It's not recommended for beginners.
The loop typically starts and finishes within the Slieve Gullion Forest Park, where ample parking is available. This provides convenient access to the trailhead and facilities.
The route offers breathtaking scenery and several points of interest. You'll pass through tranquil woodland trails, and as you gain elevation, you'll be treated to panoramic views of the Ring of Gullion, the Mourne Mountains, Carlingford Lough, and the Cooley Peninsula. Highlights include the Book of Fairy Tales Sculpture, the Slieve Gullion Summit with its Neolithic South Cairn Passage Grave, Calliagh Beara Lough, and the Killevy Churches Ruins.
The summer months are particularly beautiful, as the heather-covered hills turn a glorious purple, contrasting with the yellow of dwarf gorse. However, the trail can be enjoyed in spring and autumn for cooler temperatures and vibrant foliage. Always check weather conditions before heading out, as wet weather can make rocky sections slippery.
Yes, dogs are generally allowed on the trails within Slieve Gullion Forest Park. However, it's always best to keep them on a leash, especially in areas with livestock or wildlife, and to follow the 'leave no trace' principles by cleaning up after your pet.
The Slieve Gullion running loop is located within the Ring of Gullion Area of Outstanding Natural Beauty (AONB). There are typically no permits required for general access to the trails, and entrance to Slieve Gullion Forest Park usually involves a small parking fee, not a per-person entrance fee for the trails themselves.
Yes, Slieve Gullion Forest Park, where the loop typically begins, offers facilities such as restrooms. There may also be a cafe or visitor center within the park, providing refreshments and amenities.
Yes, this route incorporates sections of the official Ring of Gullion Way and also briefly passes through parts of The Giant's Lair trail, offering a diverse experience of the area's established routes.
Slieve Gullion is the centerpiece of the Ring of Gullion AONB, known as the most famous ring dyke in the world, formed by a circular volcano over 50 million years ago. Historically, the summit hosts the Neolithic South Cairn Passage Grave, the highest surviving passage tomb in Ireland, and the area is rich in myths, including the legend of Calliagh Berra's Lough.
Given the challenging and varied terrain, it's advisable to bring appropriate trail running shoes with good grip, layers of clothing suitable for changing weather conditions, waterproof gear, sufficient water and snacks, and a map or GPS device. Trekking poles can also be helpful for steep or slippery sections.
