Hiked from Thunder Creek Trailhead--12.6 miles total. Nice hike with a consistent uphill climb, peek-a-boo views of the glaciers at the top, it was pretty cloudy when we were up there. When you hit the Fourth of July campground, keep going about half a mile and you'll see a flat rock with a nice view to enjoy your lunch on.
About 11.2 miles and 2,400-foot elevation gain. The Thunder Arm was closed due to fire activity, so we hiked to Panther Potholes. There are a lot of switchbacks, and only peek-a-boo views. It's very scenic near the lake and creek.
