We got to the trailhead at 9:30, after driving past it once since the road isn't marked. There was one other car at the trailhead. Follow the forest service road up and at the first major fork turn right, despite what it looks like on caltopo. From then on you stay on the main road and ignore any roads off to the side. The next time you come to a major fork in the road you turn right again. The trail is well marked and obvious from then on. On the way down we encountered a lot of people and when we got down to the trailhead, at two, there were 9 other cars. We heard and saw a few dirt bikes and other motorized vehicles.

Great choice for 360 views and vitamin D. A sunny and clear east of the pass today. Parked on highway 1/4 mile up road from TH. Arrived 930 - 5 cars on highway, another 6 or so at TH. Trail dry, snow free, and in good condition. Saw just a few people on way up. Four or five parties at summit. Over a dozen parties on way down. Did not feel especially crowded. About 20 cars when we got back at 2 ish. Trail is on forest roads and ridge with low brush and not much shade so plenty of room to pass people safely. Bring lots of water.

Quick and easy hike that gets you up to an amazing 360° view! Wildflowers are blooming, two small patches of snow on the trail that can easily be avoided. Was a cloudy day and we just missed getting rained on, however the clouds were high enough that we could see for miles. Could pick out Mt Stuart and Dragontail to the North and see all the way to the wind farm near Thorp to the East.

No one else was on the trail. Parked just up the forest road below the gate. Heard some dirt bikes on the way back down but didn't see them.

What a beautiful day outside. Lots of flowers are blooming. We used the app seek to identify as many as possible. 
There is no snow at all on this trail🎉

I’ve only done this trail as a snowshoe so I wanted to check it out to avoid the crowds - yes, there are more trails in this state than just Mount Si and Mailbox Peak. We arrived at the parking area around 10:30, there were 15 other cars in the parking area. The first half of the trail routes you up through a forest road, there are several points where there are multiple ways you can go and nothing is marked so a GPS app like AllTrails is really helpful. Once you hit the Hex Mountain trail sign it gets steeper and routes you up through remains from a past forest fire. There are a couple small patches of snow but you can consider it snow free all the way up to the top. Awesome 360 views, especially of Rainier. Almost the whole trail is exposed to sun so bring plenty of water.

Watch out for dirt bikes, there were four bikers heading up behind us right below the summit and tearing up the trail. Kind of a bummer.
