A climbing tree stand platform includes a platform member having a back member and a front member separated by a first side member and a second side member, a first arm and a second arm that each extend angularly upward from the platform toward the back member, and a securing member connected between the first arm and the second arm. A first elasticized member having a first end is connected to the platform member toward the first side member and a second elasticized member having a first end is connected to the platform member toward the second side member. The back member of the platform member may selectively engage an upright support or tree while the securing member selectively surrounds it, thereby providing cantilevered support for the platform member. The first elasticized member and the second elasticized member are operatively attachable to a second platform member. A climbing tree stand system is also provided.
