My daughter and I were extremely privileged to be guided on a tour inside the Great pyramid of Cheops in 1998 by Zahi Hawas himself. It was amazing and eye-opening just as was our later tour through the 'bowels' ( storage areas) of the Cairo Museum.

Niagara Falls keeps me mindful of earth energies and Tesla. ...Giza pyramids have my interest in going especially to see more mummified CATS than there are human mummies but as long as criminal theocrat muslims run Egypt I don't feel safe anywhere near Palestine with the Nazi IDF terrorizing the poor Arabs in shrinking ghettos

Empire State Building, Grand Canyon, and, if it still counts, Niagara Falls.

Have done the Great Barrier Reef quite a few times, it is great, but I limit my visits to about a week, it gets a little boring. Than after 12 months I want to go back again for another week.

I have been to the Golden Gate Bridge and Niagra Falls.

I went to most with Google...does that count? XD

I don't know how the Empire State Building made the list. To me, it just feels like home. I never lived in the city, but I lived close enough to see it often.

I think that at 60 million years old the Giant's Causeway is the oldest of the great natural wonders of the world.

Yuss I have been to the Great Pyramids of Giza, lighthouse of Alex, and Colossus of Rhodes and the Golden gate bridge.

I still want to get to Rio, the Northern lights and the Empire State building.

You mentioned the Panama canal, though what about the Suez canal Egypt? i have been there, well under there and beside there but you cannot visit there.

Also the Parthenon Acropolis in Athens Greece, that I have been too.

Taj Mahal in India. I have not been to but would love to go to.

Just to add, in New Zealand we get the southern lights, same as the northern lights.. just southern So I have seen those

I've been to the Pyramids (shame the city and golf course are so close). We're obviously a bit limited with the rest as they no longer exist, and in the case of the Hanging Gardens may never have existed, so i'm going to propose that Stonehenge and the Avebury stone circle are added - been to both many times.

The only one of the Modern Wonders I've been to (and definitely the only one I've traveled through on a train) is the Channel Tunnel). I reckon the Millau Viaduct should be on there too, but I haven't been there either.

I haven't seen any of the Natural Wonders but I'd like to see them all, especially the Northern Lights.

It seems to me that you left one out.
