This is the best campground choice in North Yellowstone if you're looking for something in the action. It is right by the Mammoth Hot Springs, which was one of our favorite stops in Yellowstone. Additionally, elk congregate in the area, which was very fun to see. The bathrooms were kept very clean, and running water is always a luxury when camping. The spots themselves are on the small side and don't offer much privacy, but it didn't matter. Also, you are surrounded by the main road on both sides, but the road gets so quiet at night you don't even notice it. Really a great base for exploring the northern section of the park. We arrived on Sunday, September 24th, around 5 PM and got one of the last two spots! On a Friday or Saturday you would likely have to get there early to secure a spot.
