Pick a day for a drive along the Kangamangus Highway. There are numerous stops along the way that provide short hikes and little discoveries that offer some great photo ops. This would include Swift River bathing, Sabaday Falls and many others. You can start from either end (Lincoln or Conway) and find a great restaurant in either town to refresh and re-energize.
Another little side trip is a visit to Diana's Baths off West Side Road in North Conway. This relatively short and flat hike will take you to some small waterfalls and more photo ops. Unfortunately for me, Diana has never been around when I show up.
