Play facility that lets play participants experience visual stimulation, and with which a decorative effect can be attained. The play facility includes a frame, partition members attached to the frame and forming a play space, a gas-filled transparent tubular member that is arranged within the play space at the bottom of the facility, an air-filled air mat that is enclosed by the tubular member, a pressurizing device for filling the inside of the tubular member and the air mat with air to increase their internal pressures, an air-flow generation device for causing air within the tubular member to flow in one direction, and balloons accommodated within the tubular member and caused to flow and circulate within the tubular member by the airflow generated by the airflow generation device. Play participants can step onto the tubular member or the air-mat and feel their elasticity, and by seeing the balloons flowing and circulating inside the tubular member, they can experience visual stimulation.
