A tree step having an integral angle bracket with an obtuse angle forming a foot-supporting portion and a projecting tree-engaging leg with a projecting supporting arm connected pivotally and lockably to the angle bracket intermediate its ends with the free end of the projecting supporting arm having a tree-securing means thereon at the free end. The free end of the projecting tree-engaging leg of the angle bracket forms the hypotenuse of a right triangle when the tree step supporting arm is secured to a tree trunk with the tree trunk and the projecting tree-engaging leg forming the legs of a right triangle. The foot-supporting portion of the bracket projects outwardly from the supporting arm and upwardly from the tree-engaging leg.
