Instruction:
What are the different kinds of rock climbing?

Response:
The most popular types of climbing are:

- Bouldering: climbing low hanging challenges, likely with crash pads to fall on.
- Sport climbing (or indoor climbing): Climbing a route with fixed anchors
- Traditional climbing: Climbing with gear that is inserted and removed without fixed anchors

Once climbers gain experience, they are able to begin climbing more extreme outdoor terrain however many climbers may stick to bouldering or sport climbing.
