East of Geneva, the Abondance ski area has nine lifts accessing 12 pistes with a maximum vertical drop of 770m. This ski area is known to be family friendly, especially the Ludoffaz play area near the village centre.
Keep in mind that Abondance is pretty low elevation and may have variable snow conditions.
The Abondance Ski Area is part of the Portes du Soleil ski domain, but does not directly connect with it. The Portes du Soleil ski domain is one of the largest in the world linking 14 villages on both sides of the Swiss-French border southeast Geneva. The very family-friendly Portes du Soleil encompasses 206 lifts serving 283 pistes totalling 650km over 400 hectares of terrain. The pistes are classified as 41 green, 104 blue, 110 red and 28 black. From a snowboarders perspective, the classifications at Portes du Soleil can be translated as green means walking, blue means occasional walking, red means intermediate and black means difficult. In addition to the groomed pistes, there is plenty of off-piste terrain to explore under craggy peaks and down steep couloirs. Keep in mind that there are plenty of t-bars and Poma platter lifts spread throughout the region, along with flat or rolling traverses between ski areas. Overall, you are not going to find many snowboarders here, maybe 15%, except up at Avoriaz. By the way, Avoriaz makes for a great central and high elevation base to explore the entire Portes du Soleil region and it has exceptional terrain in every direction. Since the region tends to be lower in elevation, snow depth can be a problem throughout. If the quoted minimum depth is less than 60cm (24 inches), the off-piste routes are pretty sketchy to explore and you will be stuck on the icy groomed pistes. There can be some inconsistencies in published snow reports, such as centimeters reported as inches, so make sure to check several snow report sources before coming.
Overall, Abondance is the 19th most popular snowboard & freeride destination of all 42 snowboarding resorts in France.
