Circle Campground is the largest of Emily Provincial Park's four campgrounds, offering 97 electrical and 34 non-electrical sites.

Its distinctive layout features a series of pie-shaped loops arranged within a circular formation — giving it the look of a Trivial Pursuit playing piece — with electrical sites concentrated in the inner loops and non-electrical sites around the perimeter.

Sites are generally well-treed and private, lending a sense of remoteness despite the park's proximity to Peterborough and the surrounding Kawartha Lakes region.

The campground includes its own comfort station and connects to other areas of the park via short woodland pathways. Access to the Pigeon River, part of the Trent–Severn Waterway, is available within the broader park, supporting fishing, paddling, and boating.
