South of Jenbach at the southern head of the Zillertal valley, the town of Mayrhofen provides direct access to two ski areas on either side of the valley. The Penkenbahn in the center of town heads up to the larger ski area; most people also use this gondola for downloading at the end of the day. The Ahornbahn on the south edge of town heads up to a smaller, more gentle ski area perfect for families. Overall, both areas are ideal for beginners and intermediates, but expect to find long lift lines.
Mayrhofen is typically not known for it's advanced terrain except the super steep Harakiri piste or the lines off the Tux150 lift down the Penken face. But, luckily, it is part of the Zillertal Arena so you'll have access to the ski areas up at Hintertux (bus) and down at Zell Am Ziller (train). In a big snow year at Mayrhofen, try the ski route from Rast Kogel down to Eggalm. By the way, the main snowpark is the Burton Park which has three lines of kickers and rails to challenge yourself.
After a morning of shredding, head up the Schneekar lift to the top of Horberg and check out the Schneekar hutte for lunch.
The best apres ski action can be found at the Ice Bar near the Penken Gondola base or the Speak Easy Arena at Hotel Strass. For some late nightlife, try the Schlusselalm Disco and Scotland Yard Pub (aka Scotties). Whether at apres or later, stop by the Bruck’n Stadl at the Ahorn base.
If you are looking for a traditional Austrian meal, try the Wirtshaus Zum Griena which is a 400+ year old farmhouse.
To reach the snowboarding in Mayrhofen, take the train from Innsbruck or Munich to Jenbach. Then, transfer to the Zillertalbahn to head up the valley to Mayrhofen.
Overall, Mayrhofen is the 27th most popular snowboard & freeride destination of all 52 snowboarding resorts in Austria.
