Some of the most scenic vistas in Vietnam can be admired from a bird’s eye view aboard a plane that takes off from the capital city of Hanoi. Flying over the green landscape of northeastern Vietnam, this aeroplane tour is possibly the best way of seeing the limestone karst formations of Ha Long Bay. Hai Au Aviation offers this service, and although somewhat pricey, the sights you can see from the plane are absolutely astonishing. This is most likely one of the best ways there is to see the natural wonders of the bay.

Hop across the border for an excursion to the oldest German town of Trier, which contains some beautiful examples of well-preserved Roman architecture, including the UNESCO-listed city gate of Porta Nigra (Latin for 'black gate'), remains of Roman baths and an amphitheatre.

When exploring the historic city of Rimini, Piazza Cavour makes for an excellent starting point for your walk. This square, once a bustling marketplace, has evolved into one of the city's vibrant social hubs. You'll find an array of bars and shops adorning its periphery. Along one side of the square, you'll encounter some remarkable historical buildings, including Palazzo Garampi, Palazzo Arengo, and Palazzo Podestà. At the heart of it all stands the Fontana della Pigna, which, in its current form, serves as a testament to the enduring history of this place, as it dates back to Roman times.
