Abstract: The present disclosure provides a swimming pool ladder with a barrier. The ladder includes two ladder sections. A top platform for supporting is connected between the upper portions of the two ladder sections and disposed above the swimming pool. The two ladder sections are respectively positioned inside and outside the swimming pool. The ladder section includes two parallel-disposed rails and a plurality of steps. The plurality of steps are mounted at intervals along the two rails from top to bottom. A barrier is provided that is perpendicular to the inner side face of the first ladder section. The barrier has a triangle shape, one edge of which is adjacent the inner side face of the first ladder section and fixed on at least two steps through at least two connectors and another edge is adjacent the inner sidewall of the swimming pool. The top end of the barrier is spaced from the top platform by a distance and the bottom end is adjacent the floor of the swimming pool.
