Does anyone know any hidden gems between Santander and Faro??
Yes, before you get to Madrid take a detour to “Segovia”. I do know a good Hotel there if you are interested. It is a fascinating town and a “must see”. Driving south you should head for Cordoba. As it is on your route I would make that your second stop. Once there you are about 3 – 4 hours from Faro. You could even consider making it three nights and staying one night in the most beautiful city in Andalucia, Sevilla which is less than two hours from Faro.
