Driving Directions: Drive I-90 to the town of North Bend and take exit 31 into town. Continue east on the main drag, North Bend Way. Just east of town turn north on Mount Si Road (432nd SE). Turn right at the next intersection and drive 2.5 miles more to the huge parking lot. The lot is designed to hold 175 cars and includes a state-of-the-art outhouse and a picnic area.
Trail notes: The size of the parking lot should be your first clue as to the popularity of this trail. This trail is always crowded. Even on a rainy day in the middle of winter during you'll find people here. If you don't like people don't go to this trail. If you are one of those people who likes to follow the rules and expects others to follow the rules don't go here. If you don't like seeing trash on the trails, dogs-off-leashes, people cutting switchbacks, people running down the trail, people yelling, boys throwing rocks at their little sister, or "movers and shakers" talking on their cell phones, don't go here. None-the-less, Mount Si is one of the first and most prominent peaks you see as you drive east on I-90 and anyone who has lived in the I-5 corridor for more than an hour has heard of it and knows someone who has climbed it, is climbing it now, or will be climbing it next weekend. If you haven't climbed it yet, you will eventually be over-come by the immense social pressures to do so.
The trail begins as part of an accessible trail, but quickly turns into a true hiking experience as soon as you leave the short stretch maintained for wheelchairs and strollers. The trail is fairly steep gaining 3100 feet in 4 miles. The area is managed by Washington State Department of Natural Resources and in the past had been cut-over before becoming a popular recreation area (now known as the Mount Si Preservation Area) so don't expect to encounter many ancient trees with draw-dropping girths; this hike offers second-growth hemlock and cedar only with patches of alder. At about mp 1.0 is a nice view point, a good turn around spot for those starting to feel faint. Climb further to "Snag flat". Here find a short spur with a boardwalk and interpretive signs describing the natural history of the area. The summit is still 2.25 miles ahead. Climb higher and higher through small trees with few views until you pass though a rocky area and onto a large flat below the summit.
Directions. We will meet on the ground floor of the new Issaquah transit center to carpool to the trail head.
Please note:: We are meeting at 7.00 AM . This would help us to avoid little bit crowd at the trail.
