The gate might be closed when you arrive but it’s probably unlocked! We drove past the initial site listed in Dyrt because of this, then were told by a local when we pulled over on the next one to go across the highway. Not sure if this was the correct spot either as there were no established camping spots and we got a long look from a hunter early in the morning. All in all though it was very pretty and quiet, great space for stargazing. Just make sure you read the signs correctly!
