Since this campground hasn't been reviewed in a while, I thought we'd add our two cents. Sites are mostly level and private. A big 5th wheel might be able to maneuver, but not a big motorhome. Detected no noise from I-35 during our stay. Dust is a big issue, though. Road goes from asphalt to gravel/dirt almost immediately after leaving the office and it's a half mile in to the campground. Most sites seem to have full sun, we were fortunate to get one that is mostly shaded (34E). There is a $7 fee for online reservations plus the $5 per day vehicle fee (waived for tow car). Very nice little exhibit about agate in the office/visitor center. We camped here in a Motorhome.
