It was totally amazing experience to be there with seeing only 2 other people in several hours. We ended up taking a trail that starts from Ohanapecosh campground.
The trail is called Silver Falls Trail. Make sure you go to the end of the trail because the views are amazing.
Ohanapecosh campground is known for its hot springs. I can't say I was impressed. You could smell a little bit sulphur there but it's most warm muddy moss that you can see on the photo below.
