The image shows a group of people swimming in a river. The river is surrounded by a rocky cliff with trees and bushes on either side. The sky is blue and clear. In the foreground, there are several people in the water, some of them are holding surfboards and others are standing in the shallow water. The cliff appears to be old and weathered, with patches of greenery growing on it. The water is calm and there are no people visible in the image. The overall scene is peaceful and serene.
