The town of Marathon in the Florida Keys is home to a unique hospital dedicated solely to caring for sea turtles. Marine biologist Bette Zirkelbach tells us about the dangers that sea turtles face in the wild. A lifesaving operation takes place, and a turtle is treated for a mysterious viral infection.

The only coral barrier reef in the United States surrounds the Florida Keys archipelago, and has been badly damaged by environmental pressures including ocean warming. The Coral Restoration Foundation is dedicated to its salvation, and in underwater nurseries, new coral is being grown to replenish the reef.

We head northward into the great swampy wilderness of the Florida Everglades. Airboat Captain Jesse Kennon knows his way around these marshes and where to find their most well-known and well-feared inhabitant: the alligator!

Jesse Kennon’s family are the only permanent residents of Coopertown, and he takes on responsibilities as town mayor. A short way further up the coast lies Miami, once another small town, which underwent an almost miraculous growth to become the vibrant tourism, relaxation, and business hub we know today.

By the beaches of South Florida the lifestyle is relaxed, with plenty of time for outdoor activities. We meet Sean Reyngoudt, whose life changed when he lost a leg in an accident as a teenager. But that didn’t stop him becoming a wakeboarding champion and enjoying life to the fullest.

As well as attracting the rich and famous to its golden beaches, Florida’s great climate is also perfect for growing fruit, making the sunshine state one of the biggest producers of oranges in the world. We meet a citrus farmer who shows us some of the harvesting process.

Leaving behind the orange groves and retirement settlements of southern Florida, we travel on northwards, passing Pelican Island, America’s first ever nature reserve, and the historic rocket launch site at Cape Canaveral. Then we come to Daytona, which is popular with partying students and motorsport fanatics alike.

Daytona resident Gary Rosier has had a passion for automobiles for as long as he can remember, and meets every week with fellow enthusiasts to cruise to car shows in their classic cars. In Daytona, you can even drive your car onto the beach!

Rosie and Julian are in Hawaii discovering land formed from red-hot molten lava that erupted from the center of the earth. With the help of friendly volcano expert Ken and his friend Terri, they learn about a volcano that is taller than Mount Everest, and about Pele, the goddess of fire.

The travel kids visit a town almost completely covered by volcanic rock some twenty years before. There’s not a great deal left of it for them to see! They walk out onto the glassy and slippery surface of the lava flow, where volcano expert Ken takes a sample of some liquid rock to measure the temperature. It’s super hot, and Julian makes the excellent decision to keep his hands well clear!

Maggie has just landed in Mexico, and heads straight for Tulum, a once crucial trading post for the Mayan civilization, with spectacular clifftop ruins.

Annette welcomes us aboard her narrowboat home for a taste of a uniquely peaceful lifestyle that consists of navigating canals in the heart of the beautiful English countryside.

Isaac travels by van through North America with his wife and his dog. Today he stops off in Quebec, Canada to tell us a little about the culture, cuisine, and most famous landmarks of this old city.

Isaac visits one of America’s most well-loved settings for outdoor adventure, Yosemite National Park, which is famous for its iconic granite peaks, waterfalls, and roaming bears!

Isaac hikes to visit a waterfall in Canada’s Fundy National Park. The wooded and rocky park is at the end of the Appalachian mountain range and has a shoreline on the Bay of Fundy, which has some of the most dramatic tides in the world.
