Southwest of Innsbruck and southeast of Landeck, the Pitztaler Gletscher ski area is a snowboarders paradise with 16 pistes spread over 185 acres that are served by 6 lifts accesing a maximum vertical descent of 690m. It is very popular with both families and intermediate riders, and is usually good for a couple days. It is not well known for its freeriding scene, so you can find pow in the sidecountry for days after a dump. One of the better pistes to explore is Black #37 or the ski route Variante Mittagskogel from the mid-station down to the Mittelberg base station.
