A kid play tunnel comprises an elastic frame, a flexible tube coat, and sliding pipes. The elastic frame is in a spiral shape and comprises head sections and connecting sections connected with the head sections. Each head section of the elastic frame overlaps a respective portion of a corresponding connecting section of the elastic frame to form a frame ring. Each frame ring is closed and comprises a spiral end. The flexible tube coat is arranged on a whole section of the elastic frame. Two ends of the flexible tube coat are annular flexible sleeves. Each annular flexible sleeve is sleeved on a respective frame ring. The sliding pipes limit a circumferential sliding of the head sections with respect to the connecting section of the elastic frame. A diameter of each frame ring is reduced by a corresponding sliding pipe when the kid play tunnel is folded.
