Double Lake Recreation Area is run by the national park service. It is a campground and day use area within the Sam Houston National Forest. There is a large camping loop with partial hookup sites on the lake and full hook up sites a short walk from the lake. There is a 2 mile long trail/ boardwalk around the lake, a building for events, really nice group camping areas, a smaller camping area not good for big rvs but super for tents, a day use area with a swimming area, and what looked like a long mountain bike trail. This park is very close to the town of Coldspring which has some pretty good restaurants and places to shop. The courthouse square is really nice to spend time at and they have monthly farmer's markets. This is a nice place to just camp and hang out. We will be back.
