An Oak tree is a tree that can be cut with a hatchet to obtain oak logs. Cutting an oak log requires level 15 woodcutting and gives 37.5 woodcutting experience. Multiple logs can be cut from a single tree before it turns into a tree stump.
Oak trees are found in many areas that have normal trees. They are commonly cut east of Draynor Village.
Note: Any kind of trees you build in your house will not be able to be cut down.
