What are the seven natural wonders of the world?

Here is one list. The seven natural wonders are about halfway down the page.

The Great Barrier Reef
Aurora
Mount Everest
Harbor of Rio de Janeiro
Victoria Falls
Grand Canyon
Parícutin Volcano

The classical list was different:

“The Seven Wonders of the Ancient World (from left to right, top to bottom): Great Pyramid of Giza, Hanging Gardens of Babylon, Temple of Artemis at Ephesus, Statue of Zeus at Olympia, Mausoleum at Halicarnassus (also known as the Mausoleum of Mausolus), Colossus of Rhodes, and the Lighthouse of Alexandria as depicted by 16th-century Dutch artist Maarten van Heemskerck.”

@marinelife Your list is the Seven Wonders of the World. The OP is asking for the Seven Natural Wonders of the world. These are separate things, for obvious reasons. Both fascinating, though.

This link explains it all quite well.

I would have Mt. St. Helens on that list, too. Just Sayin’.
