We were a bit confused by the names of the trails on this app. It might have just been me or maybe they swapped colors on the map. The length of the trails didn't match the colors on the map they had available.
Either way it was BEAUTIFUL. We just loves it. My kids had a great time and saw a lot of neat thins. Another thing I thought is mentioned is the facility itself. The bathrooms were nice and clean and there were stations inside displayed the many different parts of wildlife in and around the Red River. It was fun and educational!
The orange trail is great for a super-easy afternoon hike. My dog and I often take this route, especially this time of year when the yellow trail gets a little muddy. There's a really neat chickasaw plum forest-of-sorts through the middle of it, where the ground is sandy. There are (quickly decaying) signposts marking various types of trees. It's almost perfectly flat, and grassy parts are mowed regularly, though you should keep an eye out for snakes since it's so close to the river.
Red River National Wildlife Refuge is my go-to hiking location in the Shreveport/Bossier area. My dog and I often head over there for an afternoon hike, and we always have a good time. The trails are very clearly marked, and grassy parts are mowed regularly. The route is crystal clear. The yellow trail gets a little muddy sometimes, but it's never been so bad that I've gotten my feet wet. There are two options: one through a sort of field, and the other along the trees by the river. The yellow trail joins the orange trail in a huge area filled with chickasaw plums and loops back to the interpretive building.
