Yep....#1 is better. The wide-angle juxtaposition of the large boulder and the bridge makes for an interesting focus. Also, the shape of the bridge, boulder and the river rocks makes a circle which helps keep attention to the main objects.
The second photo might have a better chance if the upper right area weren't so bright and distracting. As it is, my eye keeps wanting to go up there rather than staying on the stream and bridge.
