My friends and I stayed at Pine Springs Halloween weekend, first come first serve basis for reserving. We arrived around 10am and there were still 10 or so spots left, we ended up at spot 19. Even with 30+ campsites, our site was tucked away and it felt secluded. The campground is right next to the visitor center and next to some major trailheads. Bathrooms are close as well. Be sure to bring cash for your campsite deposit! :)
