I know this is a random reply, but I have! I've been up there twice in different trips. One from the backside out of gold creek, and one from south lotus creek. If I were to do it again, I would do the gold creek route up, then south lotus down. The gold creek route is really unvisited and is super duper pretty. The south lotus route isn't particularly pretty until the last 1.5 miles. Not a ton of large wildlife up there, but we did see a turkey and several smaller animals. Henry lake is fantastic for fishing and camping, and we saw some type of four-legged footprint (fox or more likely just of dog).
