We spent Christmas Day exploring Palmetto Island State Park. It's a fairly new park south of Abbeville and it's great. Beautiful swampy areas for canoeing, nice paths for wandering, super clean bathrooms, and interesting Louisiana wildlife. We saw several alligators, turtles, and hawks.
In addition to the trails, the park also has a campground and some new cabins that can sleep up to 8 people. My sister and her husband stayed in one of the cabins a few months ago and kept raving about it. I am thinking we might try to do that on a future trip home, perhaps in the summer months when the splash park is open. Did I mention there is also a cool looking splash park? To be honest, I was kind of shocked by how nice this park is. It really is a special little spot in South Louisiana and it turned out to be a perfect Christmas Day outing.
