Sam Rayburn is known for world class bass fishing. They have big tournaments there on a regular basis. I have never been to the lake until 3 weeks ago and I live just 95 miles away. We had a camp elsewhere so I'd never been. The lake is huge and there are tons of parks and campgrounds all around it.
Ebenezer is the only equestrian park. Has a terrific brand new bath house. Bathrooms on one side, individual private showers on the other. Ten camp sites with corrals, covered tables, fire rings, electricity (woo hoo

) and a poop spreader! It is not very expensive either! There are tons of trails all over the place. I image one could ride for days on different parts and never see the same thing. I did see a deer and her half grown fawn - they were gorgeous. The forest is gorgeous there, tons of flowers, ferns, berries, lots of hardwoods and evergreens. The trails are marked too, which is nice. I am going to look up the place you are talking about - I want to go ride in other places next year and need to get a game plan going!
