I have fond memories of Mayrhofen from working as a ski-guide there 14 years ago. Mainly that the off-piste was out of this world and I learned how to ski powder properly and that I was young enough to handle the late nights downing dangerous quantities of Jagermeister and schnapps - mainly in the Scotland Yard bar and the Arena night club.
The Zillertal valley is an enormous ski range and since I worked there it has had numerous chairlifts installed making the links so much quicker.
The two main ski areas from the town are the Penkan and the Ahorn mountains. The Penkan, accessed by a fast gondola system next to the Sport Hotel Strass, is the larger of the two with 49 lifts and over 150km of runs. It can get annoyingly busy though so I found it a lot better to hit the Ahorn mountain in peak season times. It now boasts the biggest Austrian cable car able to take 160 people at a time so you shouldn’t have to wait around too long to get up to the top. I found the Ahorn an ideal place to learn boarding too as it has a fantastic blue run as soon as you get there and less people around to watch you getting angry and frustrated.
There’s so much exploring to be done on the various mountains covered on the ski-pass, and accessed by frequent trains, including the massive Hintertux glacier and, if its fast, long pistes you crave then check out Zell am Ziller. For me though, the powder runs in Hochfugen are good enough to make the Rocky Mountains blush.
