For families with small children, there are certainly ski areas that are more suitable. There are two children's areas and at Furtschellas also the one or other blue slope, but the rest of the ski area consists mainly of red slopes. If the children are already a bit older and are already reasonably confident on skis, these are also doable.
For small children and beginners, the Cristins ski lift at the base station of the Corvatsch cable car in Surlej is recommended. Here at the practice slope and in Snowli's Kinderland they can practice undisturbed. If you only want to use the practice area, you can also buy a ticket for the Cristins ski lift only. For families, there are also offers for discounted ski passes at the Snow-Deal.
