- Fort Foster — A stunning old military site, with beaches and great seaside trails.
- Fort McClary — There isn’t much walking to be had here, but it’s a great spot to visit. I saw lots of Northern flickers when I visited.
- Norton Preserve — Woods and wetlands and about 3 miles of trails.
- Town Forest — This used to be the poor farm; there’s lots of interesting history in this pretty forested preserve.
- Remick Preserve — A quiet 1.6 mile or so walk in a forest.
- Brave Boat Headwaters Preserve — A roughly 1-mile walk in a wooded preserve.
- Rachel Carson National Wildlife Refuge at Cutts Island — Another lovely walk on the national refuge lane, with views of wetlands.
- Fairchild — A teensy preserve with a .1-mile long trail.
- Rogers Park — A 23-acre preserve with an old oak forest and views of a tidal creek.
- Seapoint — Two beaches are joined by a grassy bluff at this 4.5-acre preserve (limited parking, closed to non-Kittery residents during the summer).
- Eagle Point — An unmarked but well-used and short trail at the end of Philbrick Avenue brings you to lovely views of Spruce Creek from rocky ledge.
- Nooney Farm — A ~0.2-mile trail brings you through the farm, across a small meadow, and over a wetland boardwalk to a 0.4-mile loop through a woodland.
