Fun hike up to Catherine, amazing weather and views on top! The road is open and snow free, but rough. There is still intermittent snow on the trail but its melting out fast. A few points left where you might lose the trail in the upper section due to snow and one area where you'll traverse a snow field where a slip could mean a long fall - see pic. That said, I did it with just non-GTX hiking shoes, didn't use my poles. Gaia stats: 2.7 miles, 1100' ascent, 5052' elevation, 1:24 total time, 0:12 stopped time. 

Road and TH Conditions: You'll need to travel on gravel road for 5 miles or so from Snoqualmie Pass. The first section of the road is actually the worst, with large potholes that are unavoidable. Then the road is pretty good for a couple miles. The final mile has these 2 ruts that run parallel to the road, but they can be straddled. TH is just a pullout for 2-3 cars, no facilities. 

Had the trail to ourselves until halfway down when we passed one hiker. Significant snow about halfway up and needed gps to keep on trail. Faint footprints were hard to follow, so glad to have gps. Used trekking poles to help on snow. No need for micro spikes. Great views from top and loved the solitude this trail provided!

Road up was clear from snow- small amount of snow right at the TH.

Snow started right at the beginning of the TH but was pretty intermittent the entire way. If you haven't hiked this before,  I would recommend having the trail saved to your phone or using GPS, some areas would seem a bit confusing to navigate with the snow. 

My son (8yo) and i used poles, which helped a bunch, however my husband made it up fine without.  

I'm guessing this heatwave will take care of the last bits of snow. No cables at the top yet but we made it up fine.  

Beautiful and quiet hike,  definitely a favorite. 

We started the day heading to Margaret Lake but the road to trailhead was impassable due to snow on the road.
The road to Mt Catherine was rough with pot holes and ruts but passable. We were in an all wheel Lexus SUV. The trail wasn't well marked due to snow cover. There is a trail post. To begin the hike you will cross a snowfield that is well tracked. A few blow down trees on the trail but easy to navigate. We had poles but not spikes or treads and did fine. But certainly appreciated the poles. About half the trail is free of snow, the middle. Be sure to pay attention to the tracks to follow. Can easily veer off course of the trail. The last half mile up to the summit is snow covered, soft and melting. Look for the tracks. The summit was breath taking. 360° views. Mt. Rainier was big and glorious. A few small biting black flies annoyed us while we snacked. Be careful on the trek down...the snow is slick.

Arrived at trailhead about 10. Rod was clear up to 100m from the trailhead. Trail was snow covered about 75% though route findings was straight forward and we made it with just boots - no poles, spikes, or crampons. A great little jaunt!
