This State Natural Area has recently opened to overnight tent campers on Fridays and Saturdays only. With multiple mountain biking trails of varying difficulty to ride, GCSNA offers the right location no matter your biking skill.
What was lacking was better planning for the camping area. While the spaces themselves were nice and laid out well, the choice of ground cover for the tent pads left a lot to be desired. Choosing such a coarse crushed rock as the base for the tent pads was less than comfortable. Maybe this isn't an issue for those that travel with the kitchen sink and an air mattress, but those rocks killed my back and knees.
Bring a thick blanket and an air mattress and you'll enjoy your sleeping conditions as much as the riding conditions.
