You can buy for the whole Zillertal one card so you have the possibility to ski in all the different ski areas from the valley. But every area in Zillertal is exciting enough to spend time over there without getting bored. One very fabulous area is Gerlos. It was elected to one of the best skiing areas of the world. The slopes are very nice. They are very wide and you have all steps of difficulty. The area also offers many opportunities for freeriding, touring, bobsleighing and skating. So there are opportunities for everyone from the beginners to the experts. The area is huge so it takes quite a long time to get to know all the area. 3 different towns are connected to the area so you will probably see a different opportunity to stay in another hotel for the next year,
Zillertal is also famous for its close living to the nature therefore you will also get very good local food. Also the town is very nice and also in the evenings you won´t get bored. A very good area what is not so famous like St. Anton or Sölden but it does not has to hide from these areas. I think his area is a really very good choice for making skiing holidays.
