Mount Si should be experienced at least once by every hiker. In fact, a significant number of Puget Sound residents do just one hike per year, and these annual hikers almost invariably turn to Mount Si every time. In the early spring, mountain-loving backpackers and climbers use the trail as a tune-up for the coming season. Others come because the trail is one of few that becomes snow-free early in the year. And Si's payoff is incredible: views of the Upper Snoqualmie Valley, the Puget Sound basin, and far beyond.
