Coming in off of Dripping Springs Rd, you pass a large flat parking area with small sites you can pull off into, and this area is easy for any rig to access. But if you keep going all the way to the trail head and turn left, you can access more dispersed and remote camp sites just around the bend. You will need a high clearance 4x4 to get to these sites, or you can park in one of the sites in the beginning lot and hike in.  There are several large flat spots that are great for camping.  There are small rock fire rings and hiking trails throughout.  Good Verizon and AT&T reception.
