We backpacked this trail during the first week of June 2016. The high lakes basin of the Eagle Cap Wilderness was still snowed in but this trail was open. The first couple of miles were brushy but then it opened out into rock fields, Old Growth forest and meadows. There was a forest fire in the first two miles which is partly why its brushy. We only saw two other parties, from a distance, for the three days we were there. A friendly doe followed us for a bit. The wildflowers were fantastic!
