After years of travelling the world filming wildlife, it's hard to believe there's anywhere Sir David Attenborough hasn't been.
But the veteran broadcaster has revealed there's one place left that he'd really like to visit - the Gobi Desert.
He made the revelation when he joined staff at ZSL London Zoo to mark the official renaming of a Komodo dragon enclosure in his honour.

According to the Irish News, he said: "I've not been to the middle of the Gobi Desert.
"There are no animals there at all which is why I've never been but I'd still quite like to go. There are some good fossils there."
The middle of the Gobi Desert spans between northern China and southern Mongolia.
ZSL London Zoo's Komodo dragon enclosure was renamed 'The Attenborough Komodo Dragon House' at an official ceremony in celebration of Sir David Attenborough's 90th birthday.
As well as marking the internationally-renowned wildlife expert's milestone birthday, the newly named exhibit celebrates his long-standing history with ZSL London Zoo and Komodo dragons.
Never intending to be in front of the camera, Sir David's career was launched with the first series of Zoo Quest, when he stepped in as presenter in the place of ZSL London Zoo's then curator of reptiles, Jack Lester, who had unfortunately fallen ill.
With the veteran wildlife expert in attendance at the event at ZSL London Zoo, The Attenborough Komodo Dragon House was renamed in front of a group of staff and special guests, with Sir David unveiling a plaque to officially retitle the enclosure.
The zoo's resident Komodo dragon, Ganas, was treated to a special scent-trail of blood and scents, laid out for him by Sir David, before posing for some pictures behind the world-famous wildlife enthusiast.
The Zoological Society of London's Director General Ralph Armond said: "Sir David Attenborough has had a profound impact on all of us here at the Zoological Society of London, as well as inspiring millions of animal lovers around the world.
"Sir David's rich history with ZSL is something we're incredibly proud of, from his ground-breaking TV series filmed at our Zoos to becoming an honorary Fellow of the Society, and we wanted to celebrate his 90th year with a meaningful acknowledgment.
"Komodo dragons were first introduced to the British public by Sir David 60 years ago, on BBC's iconic series 'Zoo Quest for a Dragon', so we felt it was a perfectly fitting tribute to name this exhibit in his honour."
The Attenborough Komodo Dragon House is open to the public, with visitors able to follow in Sir David's footsteps. Visit www.zsl.org to find out more.
