Celebrate the summer solstice in Oak Bluffs at the annual Harbor Festival. The party rocks from 10 a.m. to 8 p.m., ranging from Washington Park to the waterfront and up and down Circuit avenue. Over 40 vendors from near and far will be in attendance as well as artists, craftsmen, antiques, music, food and faeries.

Washington Park will be the site of the midsummer faerie festival, beginning at noon. Special guest performers include Gypsy and the Punk, Everett Hoag and Enchanted Earth and Celtic singer storyteller Pat O’Brien. There will also be a costume contest with cash prizes in four categories: Wee Faerie, Light Faerie, Dark Faerie and Furry Pet Faerie.
