I went here a few weeks ago. We decided to go back as Holly had not been there. We went to Cliff Trail and Giant Steps which I went to before and Schiller Coastal Studies Center which was a new one. This was very nice with 3 miles of trails on different sides of a point and some fields and woods. There are still Preserves (trails) in Harpswell that we haven't explored. For reference this is the last visit:
