Alpine skiing: a place to learn. A great kids race program. Nordic (cross country skiing) They groom a nice loop behind the restaurant that has good trail to stride and skate ski. They also groom more trail heading toward the downhill area and up a long forest service road, for those wanting a more extensive workout. You have to take skis off and walk across the road at one point (unless the road is snow covered). The easy loop behind the lodge is suitable for beginning tour skiers. The spur to the left off that loop is for more advanced to intermediate skiers. Food: great happy hour from late afternoon 'til 6 pm with nice menu and $4 brews: worth a stop on the way down from Mt Hood Meadows ski area. More extensive menu in adjoining restaurant.
