Abstract: A climbing stick system includes the first climbing stick and a second climbing stick. The first climbing stick includes a first step support having a cavity and a mouth leading to the cavity and first steps coupled to the first step support. The second climbing stick includes a second step support, second steps coupled to the second step support and a locking member having a head. One of the mouth and the locking member is rotatable between a locked position in which the head is locked within the cavity to retain the first climbing stick with respect to the second climbing stick and an unlocked position to facilitate separation of the first climbing stick and the second climbing stick.
