For the parking area just southwest of campground:
Lots of room to park and plenty of space to accommodate those pulling trailers with snowmobiles, etc. Can start to fill up on weekends during peak hours, but less of a concern if you don't have a trailer.
Important: You must pay for parking online, in advance, print out the permit, and leave it on vehicle dash. Lot is patrolled and tickets are ~$65. If you forget, pullouts along the highway are free to park.
