They are great and really plentiful here in Texas. They are our park of choice, half price with the senior pass. always clean and well maintained, most have covered tables at each site, all have power and water, and some have sewer for a couple of extra bucks (Copperas Creek on Proctor Lake for example). In Texas there is at least one, and sometimes several COE parks on most lakes. Recreation.gov is their web site and I always carry the book "Camping with the Corps of Engineers" available from Amazon. com for a few bucks. It is a concise guide, by state, to all the parks and lists all of the amenities. We have never been disappointed. As said earlier, in the winter months some parks are closed and in others parts of the parks are closed. Also some of normally reservable sites become FIFS in the winter. It is best to check the prospective park on line before going there unless you are familar with them. I don't think I have ever paid more than 12 bucks a night . . . and they are always on a body of water and normally have boat ramps and fishing docks. Enjoy!
