Andorra is a tiny principality nestled between France and Spain. Is is also the gateway to the Pyrenees and a good place to buy cheap diesel. It is a strange tax-haven and duty free place with a population of just 77,000 people. It has the highest cigarette consumption in the world at 6,400 cigarettes per person each year. However, it may be that not all of these are for personal consumption as Andorra also has the highest life expectancy in the world at 81 years. Brexit fans will be pleased to know that Andorra is not part of the EU but will be disturbed that Andorra adopted the Euro as its official currency. Andorra declared war on Germany in WW1 but did not actually take part so was not included in the Treaty of Versailles. Technically, Andorra was still at war until 1958. 10 million annual visitors means over 1,000 tourists per resident each year. Andorra is unusual in that its airport is in another country (Spain) and so it its nearest train station (France).
Pas de la Casa 
Andorra is very short on places to park for the night. Everything is squished into two valleys giving a general sense of the country and being very steep and crowded. We stopped on top of the hill above Pas de la Casa just after entering Andorra so that the next day we could drive the rest of the way through and escape to Spain before nightfall. It is not so far to drive but the traffic and border queues can be massively time consuming. It all worked out well. Fantastic sunset and the next day, fully stocked on diesel and duty free, we emerged into Spain and started working our way west along the Pyrenees.
