Scottsdale ArtWalk is much like a large, easy-going open house for the Scottsdale Arts District located primarily along Main Street and Marshall Way in Scottsdale Downtown. “America’s Original ArtWalk,” this weekly gathering takes place every Thursday evening (year-round, except Thanksgiving) between 7 and 9 pm. That’s when all member galleries belonging to the Scottsdale Gallery Association (SGA) open their doors to the public and show off the work of the Southwest’s outstanding artists.
