So this one can be done as a snowshoe from the Mt Tahoma Copper Creek Hut. If you want to stay in any of the huts, make reservations early. I think it might even be lottery now. We did it in summer so that required bushwhacking between a couple of road systems and passing a gate that said No Trespassing. The views were nice from up there of Rainier, but it was a smoky day so likely better when it's not smoky. The mileage and elevation will vary depending on the route.
