The documentary series taking us on a journey to the islands of Cuba, Fiji, Cyprus, Zanzibar, Iceland and the Galapagos.
Six Welsh celebrities take us to these islands. Cerys Matthews, former rugby international Gareth Davies, broadcaster Beti George, journalist Dylan Iorwerth, writer Catrin Dafydd and Wedi 7 reporter Gerallt Pennant meet the people who make these islands special.
Wedi 7 presenter Gerallt Pennant is on the South American islands made famous by the expeditions of the 19th century naturalist Charles Darwin.
Gerallt is known and respected for his knowledge and passion for nature and the countryside. Naturally, the opportunuty to visit the islands, famous for its their rich range of species, was a dream fulfilled for Gerallt.
It's these islands that inspired Charles Darwin to develop his theories of Natural Selection and Evolution.
"I felt so fortunate to have the opportunity to go to the Galapagos," says Gerallt Pennant. "I'd always thought of the islands as one of the very few places on earth which you could describe as an unspoilt paradise."
Some one thousand kilometres from mainland Ecuador, the Galapagos are home to some of the planet's rarest species and creatures.
The story of survival here sums up the very essence of nature - and it has helped to build man's understanding of the world. That's why the Galapagos is a World Heritage Site.
Until recently, only a handful of people lived there, but now it is home to 22,000 inhabitants. And man's presence is threatening the islands' future.
Gerallt Pennant will ask - is it too late to save the Galapagos or can humans and widlife learn to live together?
