Slieve Gullion Forest Loop is a spectacular 28km circular forest trail that showcases the natural beauty of South Armagh. The route winds through ancient woodland with stunning views of Slieve Gullion mountain, featuring a mix of well-maintained gravel tracks and gentle forest roads. Terrain is predominantly rolling with moderate gradients, making it accessible yet engaging. Highlights include panoramic vistas from elevated sections, peaceful forest glades, and proximity to the iconic mountain summit. Surface quality is excellent throughout with minimal technical sections. Best visited April to October when weather and visibility are optimal.

Ebike Suitability
This loop is ideally suited for e-bikes thanks to its mixed terrain and rolling gradients that benefit from pedal assistance.

The beauty of e-bikes here is how they enable riders to maintain steady pace through rolling sections while enjoying the forest ambiance, and tackle occasional steeper climbs without excessive fatigue. Assistance particularly shines on the longer forest climbs toward Slieve Gullion viewpoints.
