You should have as much fun as possible, therefore it is absolutely necessary that you gage your ability correctly. Freeriding is much more demanding and exhausting then skiing/boarding on the piste. You should not overestimate.
Guess your correct level, then you can really enjoy the powder.
Level 1: You can handle all pistes without problems and want to try powder ski/boarding for the first time.
Level 2: You have already skied/boarded in powder and want to learn more technique.
Level 3: You are familiar with off piste skiing/boarding but want to learn more control in all types of freeriding terrain.
Level 4: You can surf all slopes and make the perfect line. Steep passages do not bother you. Your expert vision is focused on getting the best from the mountains.
