With a ski lift on the summit, Mout Hyak is one of the most visited highpoints in Washington. Mount Hyak is well known for the ski resort Snoqualmie East, formerly known as the Hyak Ski area, or even Pacific West Ski Area. It is the lowest of the 4 resorts around Snoqualmie Pass and the least used. Access to the peak is best after the resort closes but it is possible to snowshoe up while open if you stay out of the way at the resort edge. There are many cross country ski and snowshoe trails just west of the resort. There are some occasional good views reported but you won't see them in this trip report.

Just go up the face of Mount Hyak. The route is ovious as all the trees are removed to the summit ridge.
Walk up the road a short distance, taking a right staying on Snoqualmie Drive. Stay on Snoqualmie Drive at the next Y, soon reaching a sharp switchback. Here at this switchback is the start of the Hyak Lake Snowshoe Trail. Often a snowshoe trail exists already as it traverses over toward Hyak Creek for a route up to Hyak Lake, following blue diamonds on trees. Take this route to avoid any contact with the lower slopes of the ski resort. For a more direct route, continue further up the road, taking a right on Innsbruck Drive at the next Y. Then keep an eye out for a snowshoe trail to the right between some cabins. Following this will take you up one switchback before hitting the most western ski run of Hyak Ski Area. Snowshoers are often found climbing the ski slopes at the ski boundary/forest edge all the way to near the summit ridge at 3,400 feet. From there, another showshoe trail may cut right going to Hyak Lake. In the flats a bit further up are the groomed cross country ski trails that make easy shoeing east over to the base of the final 600 foot climb up Mount Hyak. Ski runs are everywhere at this point and the going is straightforward.
