The hike starts at the parking lot and the trail head is clearly marked, in a couple hundred yards you will begin your ascent to the top of Mount Si. The trail is well-maintained and dog-friendly, but be aware that there have been reports of bear spottings on the trail (although not very often). Most of the hike is under the shade of the trees which makes it a good hike even in the heat of summer. The trail ends on a rocky surface known as the Haystack, which can be very slippery when wet. You'll need some climbing experience if you plan to get to the top of the haystack. Discover Pass required.

Solid climb and nice views, but the soundscape is dominated by I-90 nearly the entire way.

I got engaged on Mount Si! Great day to go for a hike. Very clear and the trail was well maintained. There is a small spot where a tree has fallen over the trail and people have made a trail through it, but coming back down it’s hard to tell where it is. All over perfect day.

The rain has arrived. Trail was not really muddy or slippery, though the top was shrouded in clouds with zero views. Good exercise as usual. Tip for getting some view under such weather: at the UPPER talus loop trail junction take a detour onto talus loop trail. In about five minutes you will arrive at the talus pile. This is low enough that it can be below the clouds, but high enough to have a descent view.

Hiked it with my dog on 10/27. I am super out of shape but I pushed myself and made it up and down! I am proud of myself- as this hike is an ass kicker. It was beautiful. My dog had no issues, he’s in much better shape than me haha!!

Butt kicker, but a nice view at the top of the rocks. Only real downside is the number of people and an overall lack of trail etiquette

Great view at the top. Nice shade along the trails. Overall not too much litter for as many people that visit this trail.

Wooded hike until the very end where the view opens. Moderate hike if you’re in shape. Great view from the top.

The trail was in great shape and the weather today was perfect. The views from the top were excellent. I would rate this hike a moderate. (Excluding the Haystack)

Very difficult. I meant to do an adjacent trail, but I got the names mixed up and ended up doing this one on accident. Definitely not for beginners, but the view at the top is amazing if you can stick with it.

Difficult due to elevation. Beautiful at sunset but gets dark fast!

Solid hike with an amazing view from the top. Highly recommend going all the way and climbing up the side to the tip top. The only downside is going back down really took a toll on my knees. nonetheless I shall return for round 2.

Really great and challenging trail. Fairly steady incline and the scramble up Haystack is a nice way to cap off the summit hike!

Hard, steep but the view is worth it. The incline is almost throughout the whole trail. There are benches to sit at 2-3 places along the trail.

Solid- gorgeous forest hike. 3300 feet of gain is no joke, so plan accordingly. Bring Lots of water/food. Route finding in the rocky section is patchy, stick to the trails on the edges of the rocks. Haystack access trail is a bit hard to find, but just head to the right from the face and you’ll find it. Haystack scramble is a solid class 3, with patches of class 4 depending on your route. On busy days (Saturday’s) a helmet might be a good idea to mitigate possible rocks from above. Gorgeous views from the top. Downhill is a bit rough on the legs, but not too bad. Good stuff!
