On our way home from Long Beach, we visited the Willapa National Wildlife Refuge at 3888 State Route 101, Ilwaco, WA 98624.  It was really a treat! There is a small display room in the ranger’s work area and of course a delightful ranger. There is a short, level boardwalk area with plenty of interesting art. The boardwalk goes next to a pond, which was full of newts! For the more ambitious walkers, there is a trail that is relatively steep and has nature facts along the way. It is a lovely and challenging walk and at the end is a meditative labyrinth.
