If you are driving from Perpignan, you would come through Montlouis, Puigcerda to then arrive in Pas de la Casa, that is the only available route, and however it is not hazardous you will have to drive carefully. It should take you around 2.30 to 3 hours.
I hope you find this information useful.
Have a nice trip!

Hi. We are coming to Soldeu in the 2nd week of Easter. I've hired a car from Perpignan airport and I'm looking for advice on the best route.....I'm keen to avoid any hazardous mountain roads. Any advice appreciated! Many thanks. Kevin
