Additionally, the wider Gwydir Forest Park offers numerous other circular walks, including those around nearby Llyn Parc.

A prominent feature is the remnants of old disused lead mines, particularly the High Hafna Mine, which was a bustling industrial site between 1850 and 1919. These include old engine-houses, waste tips, and reservoirs, now integrated into the landscape. There's also a viewpoint atop a cliff edge offering scenic vistas.
