Altitude is:1300m - 3600m
A great resort, great skiing up on the glacier, ski hire staff in Hotel Aalborg are brilliant and our hotel Serre Palas was fab. The food and bars in town are a bit Sammy, with the exception of Le Cellier which is brilliant. It can be expensive to eat and drink but when your captive in the resort you don't really have a choice. Overall a great location.
Les 2 Alpes is known for party ski resort, but with that altitude and that amount of tracks for different skilled skiers i think it is good for skiing and party people
Nassfeld Austrian ski resort,

Ski resort has 110 km of tracks, which are mostly for advanced skiers, but on the bottom are track for beginners.
Snow is always in good condition, they are repairing tracks every day, even the tracks which are not commonly used.
On the end of the sky day everyone goes to the track which leads to the end of the mountain.
One track has cameras and speed sensors so you can film yourself and measure your speed, when you come home on the internet is video online.
