So I am currently looking at going to Louisiana next month I was wondering if there some good civil war battlefields or sites.
There's Pleasant Hill, which is privately owned... However the "Friends of Pleasant Hill" that run the reenactment and who've been hard at work restoring a dogtrot house on the battlefield could probably help see the battlefield. Highway runs right through it so you'll see it anyway even if you don't get to walk it. The old VFW Hall that's been closed down and the "Friends" I've always heard was built right on the spot where Texas troops broke through the line if I remember right. There's no interpretive markers for the most part, but still a good out of the way place of importance CW wise.
(One of their close higher up officers of the reenactment was completely aghast at the notion I proposed to him of tearing that danged VFW building down now that they own it and restoring that part of the battlefield to its 1864 appearance for the reenactment and improve the event with more land to reenact on instead of the exact same scenario in the exact same narrow stretch of land. I might as well have been speaking Martian...)

There's also Harrisonburg, Louisiana, where Fort Beauregard was and its remains can still be seen, (I'm hoping to make the reenactment there in late February). Three Months in Southern States offers a good picture of that site right after it was attacked, as Arthur Fremantle stopped by and examined the fort:

I could personally think of many other sites not mentioned, a couple I desperately want to see, but politically correct politicians playing politics with budgets have axed them from existence, (Mansfield almost suffered this fate I think last year or the year before), and other good places have mentioned.
Here's some stuff to get you excited, even though more than a few of the Parks are gone, (mostly forts), from public access. Dang politicians....
