Located in downtown's Arts District, just off the Sixth Street Bridge, L.A. Boulders has become a top destination for bouldering — otherwise known as rock-climbing without ropes. The gym opened in January in a vast warehouse next door to a shooting range in the up-and-coming neighborhood. Inside are three massive walls — “the Barrel,” “the Alcove” and “the Wave Wall” — which together offer more “problems” to solve than any other gym in the city. L.A. Boulders also has weights and exercise machines, a good enough assortment that some customers use it as their primary gym. Business is so brisk that the owners expect to open locations in Culver City, Pasadena and Hollywood next year. —Gene Maddaus
