The sites are nice and fairly big. Lake Hasty campground is the main area. No sites have water or sewer, but there is water available to fill before parking and a dump site on the way out. Not ideal, but better than nothing.
No 3 day rule on reservations. Went online 2 hours before arriving and went straight to camp site with no interaction with park hosts. Level site and Lake Hasty for fishing. No water or sewer hook ups.
The campsites where clean , we had electric hook up there weren't many people, it was quiet. Since we were in the offseason the bathrooms weren't open the first night but by the second night we had easily accessible bathrooms. Showers you have to pay for
