Inspired by our wonderful visit with Grandma to one of Cape Cod's Audubon Sanctuaries, we looked up our closest location and found out it's right in Cold Spring! It turned out to be quite a hike, walking along bumpy trails with tree roots, rocks, and drop-offs to the water, then climbing up and down rock covered hills. The trail follows along the water at the edge of the woods. At the end is a giant boardwalk into Constitution Marsh. You can see it here: satellite map
We are so happy to have found this gem! It is absolutely beautiful and we had a great time. We didn't see any birds in the marsh (although we found water chestnut seeds, cattails, spiders, water bugs, and lots more), but in the woods we saw a bright red cardinal, woodpeckers, tufted titmice, and warblers. Millie really wants to take her Daddy there soon. I tried to get her to say that she is a "nature baby", but she just kept correcting me, "no Mama, beach baby."
