Pros: Expansive ski area covering 250km of runs, excellent lift system connecting 4 ski areas, good nightlife
Cons: Town is south facing (can get slushy at the end of the season)
ADH is great resort no matter what your ability. The slopes closer to town are mostly blues and greens and for the slightly more adventurous the reds will lead you nicely back to the resort - you can get a great variety without travelling too far. The 250km of slopes comprises 4 separate areas, each are a resrot in themselves and cater for differing needs (quite and secluded or full-on nightlife explosion). The area boasts the longest black in Europe (16km) The Sarenne and one of the most difficult black runs The Tunnel, both accessed via the Pic Blanc glacier.
The lift systems are excellent - with very very few button or drag lifts (the boarders rejoice). In extremes of weather in particular on the glacier the opening of the lifts can be a little hit and miss at the top as the lift stations can take time to clear.
The is also a substantial cross country skiing area and the lift passes can be purchased just for those.
Off the beaten track you will find a great deal of off piste and back country skiing ... take a piste map and you can generally find your way to a lift station to get you back home again.
Excellent night life in both the new and old areas of ADH itself, the old town being quaint with very nice restaurants Ie Genepi, Au Blé Noir and Edelweiss - and newer part of the town ie Le Sporting and Pomme de Pin.
Bars to be recommended include: Etalon, Freeride, O'Sharkeys, Smithy's and Igloo.
With over 300 days of sunshine on average per year, the south facing slopes can be a bit slushy at the end of the season. But the summer season is just as much fun as the area attracts thousands of road and mountain bikers. The infamous 21 bends of the Alpe d'Huez make for a great and strenuous challenge.
