This is an amazing find in northern AL. This is the MWR RV park on Redstone Arsenal proper, not to be confused with MWR Easter Posey CG on the Tennessee River. That CG is no hookups and not designed for big rigs. This RV park consists of 70 sites (with more under construction) that are approx 25'x65' pull-through concrete pads with 50A FHU. Only sites 8-14 are back in. Check in is easy: enter through Gate 8 on Goss Rd, find your site, park, and you're done. There are 2 hosts that go around and mark all reserved sites each day. No need to check in at an office. The commissary, exchange and gas station (no diesel) are all less than a mile away. The FBI, BATF, and NASA have major facilities on base along with several major Army commands. No active duty units on the base according to the host.
There is a paved walking/bike trail very near the campground that you can take all the way around the base (12.2 miles). The nearby NASA Visitor Center for the Marshall Space Flight Center costs $25, but has plenty to do for kids and adults.
