It was a nice cave to visit and very easy. The roads are being repaired. You need to arrive 30 minutes before the scheduled ticket time. Drop off your party way past the parking lot at the visitors center. Google may route to the gate entrance, it's 6 miles past this to the parking lot
It's pitifully small compared to caves back east. Mostly a local attraction.
They have a nice trail continuing in a loop up the mountain with some small canes after you are done with the tour.
