The HOPE Outdoor Gallery is a somewhat raggedy, yet quite unique slice of "weird" Austin tucked away off North Lamar near the Whole Foods flagship downtown. An occasionally difficult to navigate lot of dirt with patches of over and under grown grass and concrete walls on Castle Hill, what may appear on the outset as random street art, this is actually a (mostly) official gallery of street art. The land, originally meant for new construction, for awhile attracted street artists and a few years ago became part Shepard Fairey's Helping Other People Everywhere campaign. While it does seem that some unofficial tagging is still present, a stop by the gallery to see so many pieces of impressive street art in one location is nevertheless quite rewarding. One word of advice, though -- it's a bit of a steep climb from one level to the next, so don't wear footwear that you wouldn't walk in.
