I spent about 5 days in Sam Houston National Forest. The campsite was pretty good in my opinion. Yes, there is plenty of sites here as this is a big National forest. I came here with my boyfriend and friend and there was plenty of room. The only downside was that it was really difficult to find dry firewood. At night it was really chilly with a breeze blowing across. The neighboring site were very respectful in talking with a low voice especially because they had a big group. The sites were quite close with only bushes dividing up the camps with a 5 second walk. We were able to visit Huntsville state park on the east side of Sam Houston National forest the next week
