The Virginia Aquarium Chalk the Walk ARTsplosion is where hundreds of artists and “wanna-be artists” gather to turn the boardwalk into an impromptu canvas of color! Artist registration takes place on the boardwalk at 17th Street, and chalk art is displayed for two blocks. At Chalk the Walk, participants draw four by four foot chalk drawings. A theme guides artists each year. All Chalk the Walk participants are encouraged to incorporate the theme in their work!
