Killary Harbour, nestled between counties Mayo and Galway, is one of three glacial fjords that exist in Ireland today. Navigate the rugged and dramatic landscape of Connemara, with its blanket bogs and dazzling beaches, by walking on the so-called Green Road, which runs alongside the fjiord.

Situated on the southern tip of Florida, the Everglades is a vast wetland preserve spanning 1.5 million acres. It is the only subtropical wetland in North America and the only place in the world where alligators and crocodiles live side by side. This expansive ecosystem is home to many endangered species, including the leatherback turtle, Florida panther, and West Indian manatee. As there is no public transportation to the park, renting a car or joining an organized boat or bus tour is the best way to get to this wildlife experience.
