This small park sits right on top of the bridge, with a privillege view of the river, the bridge and the mountains in the background. Worth taking a break to sit in one of the benches just to enjoy the view.

It depends on the time of year if the geese are migrating. We did not see geese in the field, but at least five different groups of dozens in each in the sky maneuvering around each other. It took one flock that seemed to know where they were going to head south and lead the others in the right direction.
