Mississippi River State Park is in Marianna, AR and was built in 2008 in the St. Francis National Forest. The park office and convention center are beautiful and have several learning stations and activities for kids and families. There is also a simple paved walking trail with identification points for local trees, birds, wildlife, etc.
The campground has only a few sites. I don’t remember exactly but I believe it’s only 18 but all have lake views. All sites are level with electricity, water, and tent pad. Some sites have tiered tent pads that might not be great for kids or “old knees”. If you bring your own kayak, canoe, or boat, you can launch directly from your camp site without any issue. Our kids just wanted to through rocks 😂. There aren’t many hikes but there is a 1.5 mile trail (video included) which was fun. We saw a few snakes but they were just king snakes.
MS River SP is a short drive from Memphis and is a great quick weekend getaway. There isn’t much for small kids to do when the swim beach and swim area are closed but most families will love the serenity and peace that MS River SP offers.
