12/22/2015 When today’s hike was originally planned, we were going to go up the Mt Si Road Trail and cut across and down Mt. Si. Then the snow came. We left the TH a little before 8am and decided to see how far we could get up the road trail. There was intermittent snow and slush until the turn off for the falls but it wasn’t long after that we donned our snow shoes. We were the first ones on the trail so we took turns blazing the trail until we got to where the snow was waist high. This was my first time up this trail but folks in the group figured we were past most of the switchbacks before it goes flat towards the west and Si. My watch said about 3700ft elevation. While we were standing there, another hiker came up (who had benefited from our postholing) and tried to continue on. In the 15 minutes we were standing there eating snack, he had made it another 30ft.
We turned around and made our way down (much easier!), then turned and headed up towards the falls about noon. It was clear there were hikers ahead of us but when we got past where the trail passes close to the creek, the tracks stopped and we were postholing again towards the falls, maybe about a foot or so of snow. Lunch at the falls was beautiful, as well as the views of the I90 corridor. We wore our microspikes down from the falls, the trail was a sea of slush and mud most of the way back to the cars.
Directions: From I-90, take exit 32 (436th Avenue SE). Turn left (north) over the freeway and drive 0.5 miles to SE North Bend Way. Turn left (west), and in 0.25 mile turn right (north) on SE Mt Si Road. In approximately 3.5 miles (past the Little Si and Mt Si trailheads), you will reach a small parking area on the left (directly across from 480th Ave). A Discover Pass is required to park here. Be careful not to park in the school bus zone. You will be towed.
