Bison Paddock Loop Road is for vehicles. Parks Canada does not allow walking, cycling or motorcycles on the loop, and asks visitors to stay inside their vehicles near bison. The road is unpaved, so take it slowly. If you would rather avoid a rough drive, the overlook is a separate way to see the place.
The route is seasonal. The herd spends winter in a smaller paddock, then moves to the larger summer area in late spring and stays there through fall; exact opening dates vary. Binoculars or a telephoto lens help when the animals are across the enclosure.
