Climbing is the activity of using one's hands, feet, or other parts of
the body to ascend a steep topographical object that can range from the
world's tallest mountains to small boulders. There are many different
types of climbing, such as Sport Climbing, Traditional Climbing,
Bouldering and more. My favourite type of climbing is Lead Climbing,
which is a type of Sport Climbing where I clip into pre-drilled
permanent bolts while ascending the route. Sometimes, I boulder.
Bouldering does not require clipping into bolts, nor does it require a
harness.
