I love this hike during the summer. I went March 11 and there was a lot of snow. Too much to see the actual trail for Stewart Falls. I would do this only if you are comfortable with where the normal trail would be.
Even if you don't do the hike, we still had a great time walking around on top of all the snow. You can even see where an avalanche happened and knocked over a bunch of trees. Powerful stuff!
Just a head's up: the trail is closed in the winter if you are starting at the Aspen parking lot. You can only get as far as Sundance's groomed trail before you have to turn back.
If you want to go up to Stewart Fall's buy a pass at Sundance and use their snowshoes trail.

very difficult and steep trail with cool view from the top. I recommend staying on the trail
