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.

Mmmm... The view. Worth a 5-minute pause for a drink of water and to catch your breath after the climb up the hill (both ways).

It's amazing how peaceful and close to nature this little park is - we even saw a beaver swimming in the lake, not to mention lots of birds and rabbits.
