This little campground is amazing. Very limited capacity (12 sites), and away from any busy or thru roads. Bathroom is a single, unisex, and was clean and well-kept. Crossing Box Creek to get to the campground just adds to the uniqueness of this little gem. We rolled in late, got spot #8 as it was the only one available. This site has next to no trees for shade (which makes tent camping hot) nor does #6, but the rest do. But the perk of our site was the huge wildflower field we had as a yard to the east, probably 200 yards from the forest tree line….my dog was in heaven. Saw a Momma Moose there and one calf. The mountain view of Box Peak is amazing too as the sun comes up over the east ridge. Made for great sunrises. Highly advise serious tent and small trailers/campers, to check this place out! It does welcome motor homes and big trailers too, but the dirt road to the campground is already narrow as is for medium sized campers and quickly becomes a one lane road - so be forewarned. For $10 a night, right between Teton and Yellowstone National Parks is a STEAL! No reservations needed either. First come, first serve. 11 AM is when sites open from those leaving. Good time to find the best spot is 11 to 2 or 3 (early afternoon). Good luck and leave no trace!
Noise complaints are common. It is one of just a few campgrounds with facilities in the Casper area, so parties do happen often. My advice, avoid weekends if possible, and go in the Spring and Fall, avoid summer. Less people, less bugs, and just overall much more enjoyable. Bathrooms are always clean and kept up. Sites are great for pull trailers, RVs, and tent-campers equally. Lots of room to run around if you have kids and/or pets. Beartrap Meadow is a beautiful place. Please keep it clean, leave no trace.
