Mount Hood is a potentially active stratovolcano with eleven named glaciers, about 50 miles east-southeast of Portland, monitored by the USGS. Its standard South Side route from Timberline Lodge is short and non-technical by alpine standards, which draws thousands of climbers a year, from first-timers to those training for bigger peaks. This page owns the current picture, the permit, the timing, and the honest hazards. For the full South Side route, the Pearly Gates and Old Chute variations, gear, and guide companies, see our Mount Hood climb guide.

Mount Hood is climbed year-round, but the prime window is roughly May to early July, with early May to late June the best for solid snow and ice. It is a spring mountain: by mid-summer the snow melts back, rockfall picks up, and the summit chutes can turn to bare ice or loose rock. The mountain is open and busy through the season, with the main current change being the year-round climbing permit now required above 9,500 feet. Whatever the month, conditions on the upper mountain shift from year to year, so current information matters more than any fixed description.

Few big mountains are as easy to reach as Mount Hood. A paved road runs to Timberline Lodge at 6,000 feet, the standard route is under three miles to the summit, and the peak sits an hour from a major city, so it draws thousands of climbers a year and a reputation as a walk-up. The reputation is misleading. Above the Hogsback the route steepens into snow and ice chutes of 35 to 45 degrees with serious exposure, past a crevasse and active fumaroles, and the weather can turn from clear to whiteout in an hour. Hood has a long accident and fatality record, and most of it comes down to climbers treating an accessible mountain as an easy one.

Mount Hood used to be a free self-registration. It is not anymore. A Mount Hood Climbing Permit is now required year-round for all travel above 9,500 feet, bought on Recreation.gov, and on the South Side route the three-day permit doubles as the required wilderness permit. There is also a new free uphill travel pass for moving within the Timberline ski area. It is a small cost, but an easy one to overlook, and rangers do check.

The single most important tactic on Mount Hood is the early start, closer to midnight than to dawn. The mountain grows more dangerous as it warms: the sun loosens rock in the chutes above the Hogsback, softens the snow, and weakens the snow bridges over the Bergschrund. A midnight or 1am departure lets a party climb and descend the hazardous upper sections while everything is still frozen, and the standard advice is to be clear of the rockfall zones by around 10am. Climbing late, or lingering on the summit into a warm afternoon, is how people get hurt.

Mount Hood is often a climber’s first glaciated summit, and it is a good one for it: short, accessible, and a real introduction to steep snow, crampon work, and glacier hazards. But it belongs in the same conversation as Mount Baker and Mount Rainier, not below them, because its hazards are real and its accident record is long. Many climbers use it alongside Mount Baker to build glacier skills before the bigger commitment of Mount Rainier. Test your base against our fitness standards, and brush up on glacier travel and avalanche awareness before you go.

Mount Hood builds cloud and storm quickly, and whiteouts on the featureless upper snowfields have led climbers astray on descent, a factor in some of its worst accidents. A settled, clear forecast and a hard turnaround time matter as much as fitness. The live map below shows current conditions; rely on a mountain forecast and current route reports for the summit-day call.
