As we drove around the area, we came upon an unexpected delight. Thousands of snow geese were resting in the crop fields which were part of their migration route. We were told they visit there almost every April. They aren't too exciting when they're on the ground but when thousands of them flew over our heads, it was magical.
If you decide to visit Skagit Valley in the spring, I suggest you plan to go during the third or fourth week of April; and bring a warm coat.
