A climbing tree stand includes upper and lower support assemblies for aiding an operator in climbing a tree and for supporting the operator in the tree. The upper and lower assemblies are attached to the trunk of the tree by straps that wrap around the trunk, and by cleats that are pressed into the trunk by the cantilevered weight of the assemblies. The upper assembly provides upper and lower seating positions for the operator. In both seating positions, the operator's weight is suspended below where the cleat engages the trunk of the tree. The upper seating position, which positions the operator's seat well above a railing provided by the upper assembly, is most advantageous for bow hunting. The lower seating position puts the operator's seat below the railing, allowing the operator to rest a gun on the railing when gun hunting. The stand has wheels attached to the lower assembly, and may be converted into a game cart by attaching the upper and lower assemblies together.
