A very steep trail - 3,700 vertical in four miles. The majority of the hike is heavily wooded and doesn't present many views. Near the top there are a few vistas and the view from the summit is great. Many people use this hill for strength and endurance training for other steep climbs.

Head east on Interstate 90 and get off on Exit 31 (to North Bend), then drive east on North Bend Way and in less than a mile turn left onto Mount Si Road. Cross the Middle Fork Snoqualmie River bridge at 0.3 miles and drive two miles to the trailhead parking lot (there's room for 200 cars). Parking is free as of 10/31/07.
