We stayed at The Yurt: 12/1-12/2/2018
A friend planned ahead and reserved the overnight spots through the Mt Tahoma Trails Association website.
Saturday morning, we got to the upper snopark trailhead around 9:30-10 AM and there were 2 other cars parked there. There was no snow on the drive up to the upper lot. (Note: there's no pit toilet in the upper lot, only lower lot) We took the road from the lot all the way to The Yurt. You hit a dusting of snow about .5-1 mile in. There was not enough snow to need snowshoes. We all brought microspikes but none of us used them for this trip.
The signs to The Yurt are easy to follow. On Saturday we only saw 4 other people on trail and they were staying at Bruni's Snow Bowl and decided to day hike over to The Yurt. We left the trailhead around 10:15 AM and got to The Yurt around 12:45 PM.
The Yurt is super cozy inside! The gas stove works, the oven does not work. They had plenty of water on reserve in the yurt as well. We were a group of 6 and all spent the night. The Yurt has 2 single bunk beds, 1 two person futon, and another futon that pulls apart and sleeps 2 separately. There was also heat.
Not much snow right now, I'd give it a couple more weeks for the area to get a good snow dump before you are able to snowshoe/ski the area!
