Come for the hiking trails and access to local communities like Palestine, TX and 4C Trail.
You will get to know your neighbors at this state park if you choose to camp here.
Our party was spread out between the main campground and the Day Use area sites. We enjoyed the site we had, but our friends were camping in the main camping loop which was very crowded and cramped mid-week. Personally our site was B near the playground and the ADA trailheads. Site B is kinda magical and if you like people watching than you are in luck, there is no shortage of foot traffic near your campsite. For us it was nice and hikers, passersby were very respectful.
Bundled FIrewood (donations accepted, however it is free to use)
WIFI at the visitors center is sub-dial-up speed
Bathhouse is stall type so it is not a fully private room.
Staff if friendly and helpful
Sites are all on hillside, if you have an RV/camper I would rec the pull through sites. The back in sites really only work for tent camping. For Tents, the pad sizes vary so be sure to check your tent dimensions. We saw a few sites our 4 person tent wouldn't have fit onto. (Saw the same at Lake Ratcliff)
Personally I would recommend the campgrounds at Lake Ratcliff if you are looking for spacious camping loops. Also Lake Ratcliff's bathhouse was much nicer and more ADA friendly. Mission Tejas's high quality trails are only a 20min drive from Lake Ratcliff.
Would've given this park a 4 star if campground hadn't been so cramped. Maybe my expectations need curbing. I will return for some winter camping later this year, possible even early spring as well. It is a great park, but if it is full, it feels crowded.
