Ski this huge and underrated area, with its massive easy-skiing area at the base. If you take the gondola’s second stage, confident youngsters love the bumpy, sometimes narrow blue back down. Wide pistes head off in varying directions, with interesting runs down to the villages of Vaujany and Oz.
Head up and there’s the big glacier where you can do the Sarenne, the longest run in the Alps (16km), and a black at that. Only the top section is demanding, but many children do tackle it, enjoying the seemingly endless sweep, uninterrupted by other runs, down through a long ravine. Meanwhile, if the kids are in ski school, expert parents can try the serious off-piste and steep, bumpy blacks down from the glacier. To the other side of the resort is the Signal area, or take a lift across the ravine and there’s Signal de l’Homme, with pleasing (if sometimes slushy) runs down to the village of Auris.
Take advantage of the fact that a 6/15-day Alpe d'Huez lift-pass allows you two days in Les Deux Alpes and a day each in the resorts of the Grande Galaxie (Serre Chevalier, Puy Saint Vincent, Montgenèvre and the Italian Milky Way), as well as covering the indoor/outdoor pool (with sauna and Jacuzzi), outdoor skating rink (open year-round) and one activity at the sports centre.
In summer, try everything from archery, tennis and squash to mountain-biking, canyoning, via ferrata and glacier-walking. With younger kids, there's summer luge, horse-riding and gentle rambles or hikes along 230km of lovely marked trails, some alongside lakes where you can swim. Also in summer (June/July), you might catch part of the Tour de France – a stage finish of the classic bike race generally takes place here, with riders ascending those 21 hairpin bends!
