The image shows a group of four people walking on a wooden bridge over a stream in a forest. The bridge is made of concrete and is supported by two wooden planks. The person in the front is wearing a gray jacket, blue pants, and a cap, and is holding a pair of trekking poles. He is walking on the left side of the bridge, while the others are walking behind him. All four people are wearing backpacks and carrying backpacks. The background is filled with trees and bushes, and the sky is blue. The stream below the bridge is small and muddy, and there are rocks and plants scattered around.
