Located in Front Royal, Virginia, Skyline Caverns is the closest natural wonder to the Nation's Capital. As one of the only places on Earth where rare Anthodites are displayed, the guided tour is as impressive as it is educational, including three running streams and an abundance of cavern formations. Whether it's your first time underground, or you're an expert, you can't miss this great opportunity to see one of God's marvelous creations!

(Editor's Note:  Consider extending your trip and heading to Charlottesville for a stay at the Inn at Sugar Hollow Farm.  The next day you can visit Monticello and James Monroe's house!)
