If you’re heading in the direction of Killuvullen, from the south (Cork), you’ll drive past a parking area with a sign marking the Glanagear Woods at the foot of the Nagel Mountains. The trail is part of a bigger network and can be followed all the way to Ballyhooly! It could take up to five hours to complete the 18km linear walk. We weren’t prepared to do the trail in its entirety so just had a little walk (plus my foot was hurting from an injury).
