Visiting the Grand Canyon is like gazing into the abyss of time; the world's biggest canyon is a geological marvel that has been carved by the Colorado River over millions of years.

Look a gorilla in the eye in the Bwindi Impenetrable Forest; walk with a family of endangered Rothschild’s giraffes in Lake Mburo National Park; see the world’s weirdest bird, the shoebill stork, and hear its machine-gun call, ak-ak-ak-ak-ak, in the Mabamba wetlands ...

I had no idea just how beautiful Edinburgh is. And how old.

But first, let’s take a quick trip around the city’s outskirts. Edinburgh (like Rome) is built on seven hills that surround the city. Holyrood Park is situated to the east of the city centre, not far from the historic Royal Mile, and is dominated by the distinctive shape of the 251m-high Arthur’s Seat, an ancient volcanic peak that broods over the city. Some say it was once the site of Camelot, King Arthur’s fabled court.
