The different classes used in the Yosemite Decimal System

Here I go, bringing class into it again...

• Class 1 - Easy hiking.
• Class 2 - Hiking with some altitude gain and loss.
• Class 3 - Boulder hopping, occasionally using the hands.
• Class 4 - Climbing, using the hands, but without the need for a belay (Aka Scrambling).
• Class 5 - Technical climbing with a belay (Aka free climbing)
• Class 6 - Aid climbing
