Wonderful trail, in April you might be lucky to see snow along 80% of the way with some slippery sections. It starts nicely from the campground/lodge parking and gradually increases in difficulty and elevation until the waterfall. I’d say this is mostly easy, but the end is slightly demanding, take your time and enjoy the view.
The trail is mostly covered and you should not suffer from exposure until the very last section between the rocks. You need full ankle mobility for this trail as the end is slightly more technical.
It ends up with a rewarding view of the waterfalls and the valley as a backdrop. I saw a yellow bellied marmot sleeping on a rock, good reminder this is a wild place.
