The city of Rockland has made an effort to regulate rampant seasonal Airbnb rentals, but you won’t want for options on that or other online rental platforms, and there are deals to be had.
If you’re looking for an active summer destination with the family in these parts, the summer camp/retreat known as Medomak (tel. 207/845-6001) offers an interesting lakeside set of options—as it has been doing since 1904—from archery and tennis to yoga and beer or cheese tastings. You sleep in pine cabins, and the emphasis is on the idea of living lightly on the earth—the director has a background in environmental education, and there are regular programs and workshops. Only catch? This is a half-hour inland from the prime coastal towns such as Camden, Rockland, and Rockport. Also bear in mind that the camp season only runs from late June through mid-August.
