We just so enjoyed our one day at Cape Cod. It was one of the rare days on this trip that it was not raining. Actually a perfect day just cool enough to be comfortable. We were able to do five hikes - all short - this one on the bay side was the longest at about three miles but we did not get to explore everything we wanted to do even on this one trail. We were both impressed with the scope of the park and the dunes in two areas were really fun.
