Saturday Sunday the 13th marks the return of the 17th Cambridge Carnival International festival and parade, a "colorful and festive celebration that is rooted in African traditions," and annually attracts 150,000 celebrants.
Most of the carnival itself will be centered at Kendall Square, but the enlarged, 1.3 mile parade route runs right through C-port, starting at Blackstone Street and River Street at 1pm, continuing up River Street to Mass Ave. From Central Square, it continues down Mass Avenue to Main Street into Kendall Square.
A bit more from the organizers:
Cambridge Carnival is the most unique event in the City of Cambridge. It is planned entirely by the community for the community. The organizing committee works hard year-round to plan an event that is inclusive, engaging, and reflective of the City’s diversity. The event is organized by a non-profit volunteer community organization made up of a diverse group of individuals who live and work in Cambridge as well as local businesses who desire to promote, preserve and share the history and culture of the Caribbean and Carnival traditions based on the models of Trinidad and Tobago and Brazil. The festival is a vehicle to bring together Cambridge's diverse community for a spectacular annual costume parade and celebration.
The Cambridge Carnival has come a long way since 1992 from a small street fair at University Park, to now one of the most spectacular events in the Greater Boston area. Today, Cambridge Carnival is one of the largest outdoor multicultural festivals in New England. After twelve years of growth, in 2004, Cambridge Carnival, which takes place in August every year, outgrew its Central Square location and found a home in Kendall Square. Cambridge Carnival is one of twenty-four North American Caribbeanstyle carnivals that combine wire-bending, costumes, masks, music, steel pan, street-parades, dancing, and food and craft exhibits, to display the diverse cultures of all the countries and Caribbean islands.
