The Axe Hut is a small hut located in the north of the Wilderness. A lockpick and level 23 Thieving are required to enter the hut. It is infested with aggressive magic axes and also contains three chests which may be looted.
A portal to the Spirit Realm can be found just outside it, accessible only during and after completing the Spirit of Summer quest with Jennica's ring. Entering the portal for the first time grants 11,250 Attack experience. Ghostly warriors are found inside.
