We stayed 4 nights in the B loop FHU area. The sites there are large, and spaced out pretty well. Bathrooms were clean, park staff was great. The golf course here is really nice, hiking trails good as well. 

If you stay in the B loop, you're about a two mile hike to the hiking trails fyi. The A loop is much closer to that. 

Town of Wynne not too far away for groceries, supplies. We really liked this place and will return someday ( in warmer weather).
