For cyclists and hikers … Canyon campground does have a hiker/biker campsite, and one thing that marks this out from other Hiker/Biker sites is just how quiet it is. There are lots of pitches, with food storage, picnic tables and fire pits. The staff at reception said that they had never turned a hiker or biker away. No charging facilities, but I discreetly charged a power pack at night in the toilet block. Recommend staying 2 nights and touring all the Yellowstone Canyon viewpoints.
