Yosemite Decimal System - YDS Grade

YDS Grade

The YDS grade system involves an optional Roman numeral grade that indicates the length and seriousness of the route. The grades are:

  • Grade I: One to two hours of climbing.
  • Grade II: Less than half a day.
  • Grade III: Half a day climb.
  • Grade IV: Full day climb.
  • Grade V: Two day climb.
  • Grade VI: Multi-day climb.
  • Grade VII: A climb lasting a week or longer.

The Grade is more relevant to mountaineering and big wall climbing, and often not stated when talking about short rock climbs.

    Ideas are like pizza dough, made to be tossed around, and nearly every book represents what my son’s third grade teacher refers to as a “teachable moment.”
