river rafting trip through a densely vegetated, tropical area

river rafting trip through a densely vegetated, tropical area. The water is brown and appears swift-moving. The river banks are covered with lush green vegetation, clinging to what seems to be a wall or cliff. A red and yellow paddle is visible in the foreground, indicating that the video is taken from the perspective of someone in the raft. The sky is overcast, suggesting it may be raining.
