Port d’Envalira (el. 2408 m.) is a mountain pass in the Pyrenees in Andorra, that connects El Pas de la Casa with the rest of the country. It is the highest paved road in the Pyrenees. The climb has been featured several times at the Tour de France and Vuelta a Espana cycling races. The construction of a toll tunnel to avoid the mountain pass started in 1999 and opened to traffic in 2002. The tunnel is located at an altitude of about 2000 meters and is nearly 3 kilometers long. This ride covers the last 12 kilometers of the climb. You could argue that the climb starts in the Spanish town of La Seu d’Urgell at 700m, which would make it a climb of around 47 kilometers and 1800 hm! Until the turnoff for the tunnel it is quite a busy road, but after that you can enjoy the nature and switchbacks on the highest pass of the Pyrenees!
