Site-A is where it's at for group camping (8-24 people) Site-6 is off on its own on the north eastern side which is nice. I'd say site A, 1, 6. Site 3 is okay to. All others are close to ranger station.
Bring head nets and long clothes june-july for bugs.
Long hike to get to The Overlook. Bring a sandwich and water. Hike light.
