Bone Yard map

The Bone Yard on the world map.

The Bone yard is a location in Wilderness, which is known for huge amounts of Big bones and bones respawns. It's considered one of the best places for training the prayer skill in the free-to-play version of RuneScape, but lots of PKers along with skeletons can be found there, so not many people choose this place for training prayer. It's also impossible to teleport out of there, because the Bone yard is located in level 32 Wilderness, and you must be in level 20 (30 with glory) or below to teleport. It is recommended to only take replaceable armour and weapons because of the level 25 skeletons there.
