A detachable footstep for stake pockets on a trailer allows passengers to board and dismount the trailer. The detachable footstep includes a frame, a footstep, a slip-guard, and a connector-locking mechanism. The footstep and the connector-locking mechanism are mounted on opposite ends of the frame. The connector-locking mechanism is a mechanical lock that attaches the frame to the stake pocket. The footstep is a sturdy rigid member capable supporting the passenger's weight as the passenger boards the trailer. The slip-guard is made of high-grip materials to help the passenger gain a secure foothold on the footstep.
