Crowned by sandstone outcroppings, Topanga Canyon Boulevard off the 118 is the most beautiful freeway exit in L.A. and home to an American rock climbing landmark. Chatsworth’s Stoney Point Park has long been the proving ground for an illustrious group of Southern California-raised rock stars: Royal Robbins, Patagonia founder Yvon Chouinard, and the late John Bachar, considered the greatest free climber of his generation. There’s no shortage of graffiti or nearby traffic. But L.A. climbers are as loyal to Stoney Point as surfers are to their local break. View map.
