All the gear, no idea
For the beginner skier or snowboarder it might seem expensive to lay out for the right apparel before you arrive, and there are few places that rent clothing in resort, so borrow what you can, check out the sales and online discounts. At the bare minimum make sure in addition to your trousers and jacket, that you've got a helmet, some goggles, gloves, and technical ski socks. Plus a lightweight back pack is always handy for carrying water, snacks/lunch, sunscreen and an extra layer.
Get on the bus
Plan your route from your accommodation to the beginner slopes, and use the resort's free shuttle bus ('navette') to get around until you get the knack of carrying skis and poles like the pros.
The beginner slopes
Les Deux Alpes has a great selection of beginner areas along the ‘Snowfront’ – the area at the foot of the pistes where the snow meets the town. The best to start on are by the Petit Viking lift at the Venosc end of town and the Petit Bosquet lift at the Mont de Lans end. Both these lifts are free, as are the two Coolidge lifts. There is also a good beginner area further up the mountain at the Les Crêtes area, most easily accessed via the White Eggs gondola lift.
The fun zones
For beginners, the Family Cross (a super easy ski / boarder cross that is not much more than a narrow piste with lots of hairpins) and Easy Park run alongside each other, close enough that you can easily hop from one to the other. The big red Hollywood style Les 2 Alpes sign is also in this area so you can take advantage of a few photo opportunities.
Explore
Beyond the nursery slopes, Les Crêtes is the best place for your first longer runs. The Petites Crêtes and Bellecombes 1 green runs are the ones to look for, accessed using the Cretes chairlift. Down in the resort, the snappily named ‘Access Vallée Blanche’ piste is a pleasant green piste which winds through the chalets of the Petit Plan area. At the bottom, the Petite Aiguille chairlift lets you return to the resort centre via the tail end of the Demoiselles piste. The whole Demoiselles run starting from Les Crêtes is not recommended, despite being green. It is long, narrow and very, very tiring.
Once you are comfortable on the green pistes and venturing onto blues, the runs on the glacier are well worth a visit. Not everybody will reach this stage in one week, but when you get there the views are stupendous. From 3,500m you can see across the Alpes to Mont Blanc and into Italy.
