Most people see this famous hot spring (one of the world's largest) only from ground level. However, a short but steep hike up a neighboring hill gives you a panoramic view. I like the range of colors (from the foreground, the spring itself, and the forested background), and the way in which the pedestrian boardwalk at the bottom-right leads your eye towards the spring.
