Don't underestimate this climb. People call it the world's most beautiful mountain, but the ice faces are brutal. If you aren't an experienced climber, stick to the six-day Santa Cruz trek for the views without the technical vertical wall. Spring for a guided ascent if you want to actually survive the summit. Skip the budget gear rentals in Huaraz—your life depends on your harness and ropes. Spend at least two weeks acclimating to the altitude first.
