Upper Whitewater Falls in Nantahala National Forest, NC. Transylvania County, North Carolina is known as “Land of Waterfalls” for good reason, as there are 250 unique cascades within a short drive of each other. Upper Whitewater Falls on the Whitewater River south of Sapphire is perhaps the most spectacular. There are two distinct overlooks of the 411 foot plunge taken by the river on its path to Lake Jocassee. Nantahala National Forest has developed a small park with family amenities.
