Oregon’s Mt. Hood has North America’s ski season that never ends. Winter melds into spring, which shifts into summer — all with skiing on the slopes of Mt. Hood.

Timberline Lodge runs the longest ski and snowboard season in North America. The resort runs lifts daily through Labor Day. During spring, operations transition off the lower mountain and up to Magic Mile and Palmer chairlifts. Palmer Chairlift tops out at 8,540 feet on Mt. Hood, far above tree line. Usually by Memorial Day, only those two lifts remain open to access the slopes.

Starting June 1, skiers and snowboarders can usually get access to two chairlifts every day. Snow conditions and weather dictate which chairs operate. On most days, skiers can lap the Magic Mile and Palmer Chairlifts. Terrain park features are usually installed on Magic Mile. As summer progresses, the Palmer Snowfield offers the place the ski and ride with a thin ribbon of snow descending to the parking lots.

Palmer Snowfield is recommended for skiers and riders with upper intermediate or advanced skills. Summer skiing and riding on Palmer usually runs through August.

The terrain available for the public in summer is limited due to the number of ski camps that train in lanes groomed onto the slope. At least one lane is reserved for the public. Summer lift tickets cost $60.

Timberline also runs camps during the summer season. The three- to six-day camps target performance, masters, families, and freestyle. Most are scheduled mid-June through July. Some, such as the family camps, are designed to include kids.

Mt. Hood Meadows runs the second-longest season on Mt. Hood. The resort plans to operate daily through April 28. The number and selection of lifts vary depending on weather and visitation. After the first week of April, the number of lifts often reduces midweek.

During April, Mt. Hood Meadows is running the April Vertical Challenge, a competition among passholders. The resort will give 10 season passes for 2013-14 to passholders that tally up the most vertical in April. Two passes will be given for each age category. In addition, one more pass will be given out in a grand prize draw.

Mt. Hood Meadows runs lesson clinics through April. It also celebrates the final weekend of the ski season with the Sno-Kona Pond Skimming on April 27.

Mt. Hood Skibowl has scheduled April 14 for its last day of the season. It re-opens for summer with scenic chair rides, mountain biking, alpine slides, ziplines, horseback riding, and 15 more activities.
