Can accommodate any size RV, even a big rig pulling a boat or toys. The campground is on a loop and we had no problem driving the one-way road with our 22-ft travel trailer which is 11'6" to the top of the AC.  But it is narrow with over-hanging trees.  If you have a huge big rig go in the "Exit" on the right when you get to the "Y". The campground is just inside this part of the loop, the road is wide, and there aren't any low branches. We witnessed a few locals go this way to get to the trailhead. 

Camping is on huge grassy areas with a good mix of sun and shade trees. You can pull in anywhere you wish on your site. There is a bolted-down picnic table, a bare patch on the ground for fires, and a trash can at each site. A vault toilet is located a good walk away at the trailhead/picnic site. There is also a horse corral at each site (a horse is not required). One of our neighbors used their corral for their kids. 

We had a bad first night with someone pulling into the trailhead at 00:45am and blasting their speakers for about 3 hours. We called FWC but don't think anyone responded. This repeated again the second night.  And on that night, some tent campers arrived to find someone squatting in their site.  They set up camp a short distance away and the squatter disappeared the next morning.  I saw a Sheriff car drive through the third day, and he gave me his card with a phone number in case it happened again. 

The trash cans were overflowing when we arrived and were finally emptied on the third day. The vault toilet could use some attention. There was a bit of trash strewn about at our site, which we picked up. 

On the good side, the camping is close to lots of rivers and springs, and there are several hiking and biking trails in the area.  The sites are huge and fairly level.  If this area were patrolled to keep out the partiers it would be an awesome place to spend a few days exploring everything the area has to offer.
