El Pas de la Casa is a ski resort (part of the Grandvalira resort), town, and mountain pass in the Encamp parish of Andorra, lying on the border with France.
One of these card was bought by me in Andorra a few years ago and the other two were sent by Heidi and Carla.
Its name literally translates as "the pass of the house" and refers to the fact that until the early twentieth century there was only a single shepherd's hut overlooking the pass. The pass marks the watershed of the Pyrenees, being the only point in Andorra where water drains into the Atlantic Ocean, and is the source of the Ariège river.
At an elevation of 2,408 metres (7,900 ft) it is one of the highest points on the European road network.
The two main sources of wealth are trade, which generates a border tourism, especially people from France through its warehouses without taxes and winter sports, with the ski slopes of Grandvalira.
The ski resort of Pas de la Casa sits below the pass on the side closest to France, and below the Pic d'Envalira (2,827 metres (9,275 ft)). Its first ski lift was opened in 1957 and it now has 31 lifts, 100 kilometres (62 mi) of pistes and 6.26 square kilometres (2 sq mi) of skiable terrain.
