A skiing area that is part of the Oberstdorf / Kleinwalsertal resort. It's not huge in size, but there are some very nice and well-maintained pistes, mostly quite high up. We visited in February '12, and as in most of the Alps there was loads of snow - so much that for a couple of days all the upper lifts were closed due to avalanche risk.
The skiing area straddles the German / Austrian border and most of the skiing is just on the German side. There are two ways of starting skiing here: one way from Oberstdorf is drive up the Kleinwalsertal road into Austria to Riezlern and catch the long gondola (signs for Kanzelwandbahn) to the top. There is a long (about 4.5Km) red piste that comes to the bottom there with a small fun park. At the top you can then link to the Fellhorn area in Germany which has a similar length but to my mind slightly steeper piste down to the German valley. To start skiing from the German side (there's slightly more parking) head for the signs to Fellhorn or Skiflugschanze. This will take you past the cross country skiing area and the huge ski flying stadium (not the ski-jumping Erdinger arena on the other side of town). It's about the same distance either way.
Up the mountain the uplift is fairly standard, mostly chairs. There are some unpisted "Skirouten" which demand some technique and some nice cruisy reds and blues. One or two bits are labelled black but aren't very long or too demanding. There is a largish fun park (Almdudler sponsored, so follow those signs). There are nice huts - I liked the one just down the Austrian side for its stunning views.
There are some good webcams and livecams on das-hoechste.de which also provides latest piste status and info.
All in all, I liked it here. Good family skiing.
