irt World in Richmond, California is one of the most unique urban BMX and pump track spots in the Bay Area. Built by the community on an old stretch of the Richmond Greenway, this place mixes real graffiti walls, asphalt lines, dirt jumps, and pump tracks all in one location. In this full tour we ride the entire park — the BMX track, the pump lines, the jump lines, and everything in between. Whether you’re local or just rolling through the East Bay, Dirt World is worth the stop.
