Hangar 18 Mission Viejo, Mission Viejo

The bulk of TruHold's indoor facility pops with colorful holds peppering a looming rock wall. Arranged by levels clearly marked "0" through "5," the grips skirt along the face of a specially designed, angular climbing wall that shifts from a steep 50 degrees to a beginner-friendly 10 degrees. Built for the bouldering style—ascending diverse terrain quickly without ropes or harnesses while dodging boulders hurled by an angry cyclops—the wall juts out over a lushly padded crash mat that cushions climbers. Experienced and professional bouldering climbers offer clinics, classes, gear rental, and open-climb times at their 4,200-square-foot indoor facility, all in the pursuit of welcoming uninitiated climbers into the fold.
