One of Northwest Argentina's most spectacular days in the saddle. Provincial Route 33 climbs from Salta's subtropical Lerma Valley through cloud forest to the 3,348m Piedra del Molino summit, then descends into Los Cardones National Park — a high-altitude desert filled with giant cardón cacti. The final RN40 leg to Cachi runs on legendary gravel through the Calchaquí Valley, framed by the Sierra del Apacheta. Surface alternates paved and graded gravel; altitude can cause headaches.
