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.

Great trail - started out @ 9:30am. The parking lot was mostly full. The trail is very clean and nice. Got back down @ 12:45. The whole trail round trip took around 3 hours. Much shade and very fun trail. 9/10 recommend!!!

Great trail for a workout. Holy switchbacks Batman. Went on the Fourth around 10a and not as bad traffic as expected. About 4.5 hours round trip.

The trail was great! I still followed my GPS after a few times of following the wrong trail. The switchbacks were definitely a hike but I felt like the old mailbox trail was much steeper than this one. Overall, great hike. Finished in 3.5 hours. I got there at 1:30 and lots of spots left. But it was foggy too.

This was my first hike in almost 3 years and I still managed to do it in under 4 hours. Reached the parking lot at 11 am and it was almost full. It's mostly steep so be ready for a leg burnout. Overall a great experience especially at the summit. The view is great!

Covered trail until the very top. Definitely not for faint of heart, but worth the leg work out with the incline. Heavily trafficked up and back, so definitely bring a mask!

Hard trail, took me about 4 hours (about 8 miles round trip)to complete. keep in mind you’ll need a discovery pass (day pass $10) which can be purchased from local gas stations or online and printed ahead of time to put on your dashboard.

The parking lot has several potholes, so be mindful when driving through. I arrived at 8:30am on Saturday. Parking lot was about 1/8 full. The weather was overcast with a light drizzle at the summit. The trail itself has coverage from the foliage up top. The trail was well-maintained.. saw a tidbits of garbage here and there nearer to the top where the rocks are, because there's where people tend to sit and eat their lunch. The last 1/3 of the ascent is a real ass-kicker with a lot of steep steps and overall incline, but reaching the top is worth the effort. The rocks at the summit were not slippery (follow the trail, you'll be fine). Per Governor Jay Inslee's most recent statewide order, we are supposed to wear face masks when out and about. In my estimation, 3 out of 10 people I saw on Saturday morning to afternoon were wearing the masks. I think it's a safe bet to at least keep it on your chin and pull it up when passing by people, and especially at the top. Just my last 2 cents.
