This ski area extends along the Ziller Valley from Fugen right up to Hintertux and includes, effectively, Fugen, Hochfugen, Kaltenbach, Zell-am-Ziller, Gerlos, Mayrhofen, Lanersbach and Hintertux.
Mayrhofen is, perhaps, the best known of these resorts and is probably the best place to stay for its lively nightlife and its easy access to the Hintertux glacier.
Kaltenbach is now linked to Hochfugen and has deceptively extensive skiing, with some interesting, long runs and some accessible off-piste.
Zell-am-Ziller is linked to Gerlos, a nice place to stay, with some lovely hotels. The skiing here is largely intermediate and there are several long red runs.
The efficient bus and rail services-free on your lift pass-allow you to ski several of the valley resorts in a week. Zell am Ziller is well worth a visit.
For apres ski, try Scotland Yard or Win-Win. Mo's is good for burgers and cocktails and the Cafe Tirol serves good food at reasonable prices. Manni''s serves some traditional dishes and several of the hotels have excellent restaurants. The Strass Hotel is the most convenient place to stay. The Neuhaus serves a super meat fondue. Neilson's Chalethotel Ferienhof is a nice place to stay if you prefer a bit of peace and quiet and is handy for several bus routes.
The ice bar at the foot of the Penken Gondola is a must for wilder spirits immediately after skiing but leave before throwing out time.
Two activities not to be missed are the hour long tour under the Hintertux Glacier and a ride or two on the Arena Coaster at Zell am Ziller. The latter can be done after a bit of apres ski at the gondola base station. Both are good for non skiers.
