Snowboarding has a steeper start than skiing. The first day involves a fair bit of sitting down in the snow, usually faster than you intended. Stick with it, because once the basics click the progression is quick, and linking your first proper turns is hard to beat.
Lessons are the shortcut. A good instructor gets you sliding, turning and stopping safely, and saves you days of guessing. Beginners spend time on gentle slopes learning toe and heel edges before heading anywhere steeper.
The instructors on adventuro run lessons and guided days for every level, from never-strapped-in to riding the whole mountain. Wrist guards and a helmet are well worth it, and so is a sense of humour.
