In the ski resort it is quite easy to find a suitable instructor for skiing, as there are two ski schools. To understand the basics of skiing you can buy a one-time pass, which will cost 40 EUR. If you want to get a higher quality of alpine skiing you should buy a five-day pass that costs 175 EUR.
Besides that there is a possibility for group skiing which is considerably cheaper and costs 10 EUR per hour. In Courmayeur there are also instructors who give skiing lessons for children.
If you already know how to ski well enough and want to learn all kinds of extreme tricks or to master another type of skiing, experienced instructors will help you to achieve this goal as well.
