A ladder tree stand comprises a ladder, a platform carriage multi-pivotably coupled to the ladder, and a platform movably coupled to the platform carriage. A hinge comprises a first post and a male hinge node extending therefrom, and a second post and a female hinge node extending therefrom. The male hinge node and the female hinge node are configured to mate together and to cooperate to pivot relative to each other about a first axis, prevent substantial rotation of the first post relative to the second post about a second axis, and limit a pivotal range of motion between the first post and the second post. A foldable ladder comprises a first runged section, a second runged section, and a hinge pivotally coupling the first runged section to the second runged section.
