I don't think I saw caverns and the Natural Bridge posted yet. (Maybe I missed it). There are the Luray and Shenandoah and Endless Caverns - all really beautiful. And there is the Natural Bridge which is a nice little easy hike and the scenery under and around the Natural Bridge is quite nice.
I also love all the country roads through the Shenandoah Valley, and the George Washington Forest has endless trails for jeeps, motorcycles and mountain bikes.
There is also the Eastern Shore with quaint fishing villages and nice places to camp or ride or drive.
I am disappointed this thread hasn't been posted for a few days! Virginia is beautiful and of course, who can forget, VIRGINIA IS FOR LOVERS ... it's a romantic state
