Standard Campground, but Excellent Hiking
Brainard Lake Recreation Area has some really great hikes to alpine lakes, and Pawnee campground is the place to stay if you want to be the first person on the trail. Overall it is your standard large campground - the sites have grills, fire grates, picnic tables, bear boxes, and are fairly close to one another. The campground also has clean restrooms and you can book your site online.
There are a lot of moose in the area! I have been here twice and I have seen moose both times. Once was just along the road, and the other time I saw 2 moose while I was hiking to Lake Isabelle. Also, the Lake Isabelle hike is one of my favorites - I recommend coming here just to do this hike. It is helpful to stay at the campground the night before because the trailhead parking lots fill up quickly.
