What is the biggest city, other than its capital, in Andorra?

The biggest city in Andorra, other than its capital, is Escaldes-Engordany.
Escaldes-Engordany is the second most populated parish in Andorra. Those who wish to live in Escaldes-Engordany opt for a booming and modern living environment. The existence of the hot springs has led this parish to make major investments in the spa tourism sector. Located in a large, sweeping valley, Escaldes-Engordany affords its residents the ideal combination of modern life, peace and quiet; with all the services they need, just steps away.

The climate is Mediterranean, yet with the noted influence of the high mountains. This can generate extreme conditions during the winter, with cold and snow, making it is common to see sub-zero temperatures. Living in Escaldes-Engordany during the summer is frankly wonderful, as the temperatures are mild and seldom exceed 30 degrees Celsius.
