Abstract: A convertible wheeled backpacking accessory attaches to a backpack to carry the backpack over both rugged terrain and rolling terrain efficiently. The convertible wheeled backpacking accessory includes a cradle that has a cradle frame covered in part by a cradle material wherein the cradle can support the backpack. Frame pegs are attached to the cradle frame which pierce the cradle material and can accommodate wheels when the backpack is being carried over the rugged terrain. A frame axel is attached to the cradle frame and extending outside the cradle material. The frame axel can accommodate the wheels when the backpack is being carried over rolling terrain.
