1. Potosí, Bolivia
The Bolivian city of Potosí is reportedly the highest city in the world, sitting at 4,090 m (13,420 ft) above sea level. The peak of Cerro de Potosí, or Cerro Rico – Rich Mountain, dominates the city’s skyline, and towers a further 800 m above the rooftops.
2. Quito, Ecuador
Sitting at 2,850 m above sea level and around 22 km from the equator is the Ecuadorian city of Quito. It is flanked either side by the Andes, and on a clear day it’s possible to see the snow-capped volcano, Cotopaxi in the distance.
Close to the Tibetan border, 12,630 ft high above sea level is the small secluded town of Laya. It is one of the most remote towns in Bhutan, so remote that routes to the area are often closed or impassable over the winter months.
4. Assekrem, Sahara
It’s hard to believe the area around the towering peaks of the Atakor Mountains are populated; the area is so dry and desolate. But even here life goes on, in a city located around 2,728 m above sea level, called Assekrem. The city lies on one of the oldest trade routes through the Sahara.
5. La Paz, Bolivia
La Paz, also in Bolivia like #1, is a sprawling city 3,500 m above sea level and home to just under one million people. It’s in a great position for those who want to spend some time visiting a number of sights at altitude – the old ruins of Tiahuanacu are nearby (much older than Machu Picchu), as is Lake Titicaca.
The tiny Principality of Andorra is a small landlocked country nestled in the Pyrenees mountain range, between Spain and France. The whole country is no bigger than 470 sq km (181 sq m) and the highest of the peaks – Coma Pedrosa – is 2,946 m (9,665 ft) above sea level. It’s also one of Europe’s most popular ski destinations.
7. Machu Picchu, Peru
No list about cities in the clouds could be complete without the ancient city of Machu Picchu, high in the Andes. Thought to be built between 1460 and 1470 AD, the city sits at 2,430 m above sea-level and is often covered in cloud. The UNESCO World Heritage Site is popular with trekkers, some would say almost too popular.
