Mt. Hood is home to (amongst other things) five ski areas (three of them major) and boasts North America's longest ski season thanks to a dependable snow pack that lasts through summer months.
Timberline Lodge Ski Area is noted not only for its 3,690 vertical feet and national historic landmark lodge but also for the fact that you'll find all lifts up and running through Labor Day, with a serious fall season on Palmer Snowfield.
Mt. Hood Skibowl is only 52 miles east of Portland (the closest of the bunch) and is popular for its selection of black diamond lighted runs, the perfect ski fix for those with regular nine-to-five jobs.
Mt. Hood Meadows gets an average snowfall of around 430 inches, so you can expect to find here (in addition to panoramic views from the lift-served heights) plenty of fresh powder to pad your descent. This is also the more protected of the three ski areas and sits on the sunny southeast side of the mountain; look for 11 operational lifts and 15km of groomed Nordic Trail.
Cooper Spur, on Mt. Hood's northeastern shoulder, is accessible from the town of Hood River, a family-friendly option that has enough gentle runs to suit even novice skiers; there's one rambling lift here, a rope tow and some good cross-country trails. Summit Ski Area is similarly suited towards beginning skiers but also has some great sledding slopes to its credit.
