This relatively new east–west road heads toward Laguna San Rafael, but stops short at a water crossing. Gorgeous but rough, it is still a worthy driving or biking detour, crowded with glaciers and overgrown nalca plants. Keep an eye out for the Glaciar Exploradores Overlook (CH$4000 trail fee) at Km52. Day-trippers to Glaciar San Rafael usually meet their outfitters at the end of the road.
