Prior to enjoying your Maine beaches vacation, be sure to check out town websites for festivals and other special occasions. Many of these events are free and family friendly. In addition, town common concerts -- a mainstay of summer activities -- often feature undiscovered, high level talent to be enjoyed. Also be sure to check out the Prescott Park Arts Festival, located in nearby Portsmouth, NH, for free or very affordable summer outdoor concerts and theater productions that are popular with all ages.
In the meantime, welcome to Portland and the Southern Maine Beaches - and enjoy!
