An outdoor swimming pool with clear turquoise water is shown from an elevated perspective. Several children, primarily young, are engaged in swimming activities. In the foreground, a group of five children are congregated near the shallow end of the pool and a set of pool steps. Two children, one in a pink swim cap and light blue swimwear, and another in a white swim cap and patterned swimsuit, are floating on their backs. A third child in a dark swimsuit and white cap is holding onto the pool steps, while another child in a pink cap appears to be submerging. An adult, mostly out of frame on the right, stands by the pool edge, seemingly supervising or instructing the children. Further down the swimming lanes, other children are actively swimming, creating splashes in the water. The pool features visible lane lines. The surrounding area includes tiled paving around the pool and some distant greenery and structures under what appears to be an overcast or bright daytime sky. No discernible text is visible within the frame. The scene suggests a swimming lesson or recreational activity at a public or private pool in Nha Trang.
