If you want to see wildlife during you Yellowstone adventure then Slough Creek Campground is the way to go. During our visit we got to see Bison on our drive coming in, deer feeding at the edge of the campground and watched a black bear for 30 minutes just a mile down the hiking trail. But to get a campsite you have to be prepared, prepared as in get here in the early morning so you can grab a sight as soon as one become available, this campground is often full by 8am if not earlier. You can leave the RV crowd behind here, most campers are tent camping or just have a small camper, the bigger on won't fit here. A nice quiet campground with Slough Creek running right next to most of the sights made for a good nights sleep. All sites have picnic tables and a metal fire ring. This is bear territory and you need to lock up those food items in your car/truck or in one of the bear proof lockers located through out the campground, just be ready to share with other campers. Site has some of the cleanest vault toilets around. Trash and recycling is available as well. Water is from a hand pump and the water is top notch. If you like to star gaze then you can't do any better than here, no light pollution lets you see everything our night sky has to offer.
