I didn't stay at the campground because I prefer to camp alone. There are lots of dispersed camping along the first road 295 (which leads up to Knoll Lake). Coconino National Forest allows camping up to 300ft from the road. According to the rangers, bears are active in the area so it's important to follow the safety protocols. Spent the day on the lake which is well worth the extra drive to avoid the crowds at Woods Canyon. Found one spot with cell service where you turn off fr300 towards Knoll Lake.
