Piste map - Zermatt Matterhorn - Zermatt Tourism
Zermatt is open all year. Top cairlift is at 3899m. The scenery is phantastic with all the glaciers view at the Monte Rosa Dufourspitze with 4636m and from most slopes you see the Matterhorn 4478m. Worth a weekendtrip. Last year mid April we even had fresh pow (lot of sidecountry at Rothorn and Stockhorn)
I was looking at Zermatt as well but it seems like a bit far (6 hour drive). I'll still see if I can visit, but Hintertux seems very doable. It's so close that I can possibly do a day trip.
I live in Prague, a friend of mine has a place in Kitzbuhel and I met up with him there back in January to do some skiing. I took the bus to Munich, which was a pain but then the train from Munich to Kitz was great. I'm not sure if you can get a train from Munich all the way to Hintertux but I'm sure theres a way. Just keep in mind, depending on the day you choose your trip, it'll either be easier or more difficult with transfers. I got lucky and only had to transfer to another train in Worgl but if I went a day earlier or a different time I'd have to change trains like 3 or 4 times so you end up pin balling back and forth. Check the DB website bahn.com and book your ticket on there as well.
Renting a car would definitely be quicker especially for a day trip, if you can afford it then go for it. Never skied or snowboarded on a glacier so I couldn't tell ya. I'm supposed to go to Hintertux end of this month, so if I do go I'll let ya know how it is.
Is boarding on a glacier much different than piste riding?
Rather hardpack, flat blues. I try to avoid the glacier runs if I'm in Zermatt. The same on glacier in Saas Fee. Guess, it's common that glacier slopes are flat cause on steeps you'd have crevasses... (?)
