Lots and lots of dispersed spots off this highway. Clearance needed to reach some of them, but are great clean gorgeous spots. Highly recommended.
Dirt road access off of the Mirror Lake Scenic Byway just past Sulpher Creek campground. Got pretty cold at night and there was a number of other tents and RVs taking up most of the spots – we got there around 6:30 on a Friday evening and were one of the last ones to get a spot. There's plenty of dispersed sites along that highway though. Camped in the meadow and watched a mom and baby moose grazing while we set up camp.
