You don't need any special prerequisites as long as you have a normal level of fitness. However, you should bring functional clothing, technical material and sun protection.
The technical material usually includes:
- touring skis or splitboard with touring binding and touring boots
- telescopic poles
- crampons
- skins
- avalanche transceiver, shovel, probe
However, the organizer of your avalanche course will tell you exactly what you need to bring or can borrow.
