The Pyrenees are among Europe's highest mountain ranges, separating Spain and the rest of Iberia from France and the rest of Europe. Sections of this mountain range have been designated as UNESCO World Heritage Sites.
The Pyrenees are highly accessible thanks to numerous airports the length of the chain. On the French side at the Atlantic end, Biarritz/Bayonne is the closest airport to the mountains although Bordeaux airport is only a couple of hours away. Further East, Pau and then Tarbes/Lourdes airports are in the central foothills whilst Toulouse is the major hub serving the central Pyrenees. Carcassonne and Perpignan airports serve the Mediterranean end of the chain.
There are numerous crossing points which take the traveller from the French to the Spanish side of the mountains. In the centre of the chain, a road runs alongside the River Garonne from Saint Beat along the Aran Valley and into Spain. Further West, the Bielsa tunnel up from Saint-Lary-Soulan is a well frequented crossing point as is the Puymorens tunnel which is on the main Toulouse to Barcelona route.
