Seefeld is a classic winter holiday resort, well designed in traditional Tirolean style, with a large pedestrian-only centre and lots of upmarket hotels (including three 5-stars).
There are two main downhill sectors on the outskirts - Gschwandtkopf and Rosshütte - the latter served mostly by fast lifts. Both areas have intermediate runs of decent vertical; Rosshütte is more extensive, with a cable car across to the separate peak of Härmelekopf, and some worthwhile challenges for experts. There's a good long red run back to village level and a gentle nursery area too. The ski area is well suited to beginners and early intermediate, though overall the terrain is too limited to keep most folk entertained for a week's stay. Lots of people come here to enjoy the superb cross-country trails and off-slope activities rather than the downhill skiing.
You can always make excursions to Innsbruck, not far away and easily reached by train, or to the Stubai and Zugspitze glaciers. The proximity to Innsbruck - just 30 minutes, makes transfers a delight as well.
