Grosse Pointe's Greatest Block Party is a late-summer community celebration that features food and refreshments, music, art, a pooch parade, children's activities and fun for the entire family! This great event takes the time-honored tradition of the neighborhood block party and brings it right into the heart of Downtown Grosse Pointe! The Block Party covers two entire blocks of Kercheval Avenue from St. Clair to Cadieux in The Village, Downtown Grosse Pointe.
