After nearly three decades, the annual Cambridge Carnival International is still going strong, yet again taking over the streets in and around Central Square for its 29th year on September 10 from 11 a.m.–5 p.m. Modeled after the vibrant celebrations of the Caribbean, this lively and free spectacle features a colorful, one-mile parade beginning at 12:30 p.m. that goes from River Street up Massachusetts Avenue and on to the main festival area along Sidney Street across from University Park Commons. Witness dancing to rhythmic music as well as dazzling, feather-adorned costumes inspired by the islands. The grand revelry also features a main stage near Auburn Street that hosts a variety of Caribbean-tinged musical and dance acts as well as a stage along Green Street and a KidsFest section at the park that lies near a host of arts and crafts vendors. And don’t forget to partake the delicious food that can be found all along Sidney Street while you witness performers stomping their feet and playing steel drums, calypso, reggae and more at this unique cultural extravaganza.
