I was there last weekend. A few days after snowfall. Trails were quite snowy, but it was a sunny day.

If you do any intense hiking (steep), you won't need as many layers as you think, as you will SWEAT!

Been sunny this week though, so perhaps most of the snow has melted by now. Still, I certainly would recommend carrying shoe spikes and walking sticks to help your balance. I didn't have either, and while I did make it up a mountain, I mostly had to sit down and slide to come back down, else I risk slipping and hitting my head.
